What a Sleep Specialist Does and Why It Matters for Long-Term Health

A sleep specialist diagnoses and manages conditions that disrupt the architecture of your sleep, from obstructive sleep apnea and central sleep apnea to insomnia, restless legs syndrome, REM sleep behavior disorder, and periodic limb movement disorder. Sleep medicine is a recognized medical subspecialty. Physicians earn DABSM (Diplomate of the American Board of Sleep Medicine) certification after completing a fellowship and passing board examinations.

Sleep medicine is a subspecialty that intersects with pulmonology, neurology, psychiatry, otolaryngology, and cardiology. A sleep physician evaluates brain waves, heart activity, oxygen level fluctuations, airway patency, and respiratory effort during sleep to build a complete diagnostic picture. This matters because fragmented or disordered sleep does not just cause daytime fatigue. According to the National Heart, Lung, and Blood Institute, chronic sleep disruption is linked to elevated cardiovascular risk, metabolic dysfunction, and immune impairment.

What most patients do not realize is that the downstream effects of untreated sleep disorders show up in blood biomarkers long before symptoms become severe. Markers like hs-CRP (a measure of systemic inflammation), HbA1c (a gauge of blood sugar regulation), cortisol, and ApoB (a cardiovascular risk marker) can all shift measurably in people with chronic sleep disruption. This is why programs like Dumbo Health's sleep longevity membership now pair clinical sleep care with biomarker testing, using a metric called SleepLongevityAge to track how sleep is influencing your biological age over time.

DID YOU KNOW: The National Institute on Aging notes that biological age can diverge significantly from chronological age, meaning two 50-year-olds can have very different aging trajectories depending on sleep quality, inflammation levels, and metabolic health.

KEY TAKEAWAY: A sleep specialist does more than treat snoring; they diagnose conditions that accelerate biological aging, which is why connecting sleep diagnostics to biomarker data gives you a more complete picture of your health.

Understanding the types of sleep disorders a specialist treats is the first step toward knowing which diagnostic pathway is right for you.

Common Sleep Disorders Diagnosed in Philadelphia

The most frequently diagnosed sleep disorders in Philadelphia and across Pennsylvania include obstructive sleep apnea, central sleep apnea, complex sleep apnea syndrome, insomnia, restless legs syndrome, REM sleep behavior disorder, periodic limb movement disorder, and circadian rhythm disorders. Each condition affects sleep architecture differently and carries distinct health risks.

Obstructive Sleep Apnea

Obstructive sleep apnea is the most common form of sleep apnea. It occurs when the muscles at the back of the airway collapse repeatedly during sleep, causing partial or complete blockages that reduce oxygen level and fragment sleep cycles. These events are measured as apneas (complete cessation of airflow for 10 seconds or more) and hypopneas (partial reductions in airflow). According to the American Academy of Sleep Medicine, obstructive sleep apnea affects roughly 12 percent of the adult population, with prevalence increasing with age, BMI, and male sex.

Untreated obstructive sleep apnea is associated with elevated cardiovascular risk, hypertension, stroke, type 2 diabetes, and cognitive decline. Snoring is the most recognized symptom, but many people with obstructive sleep apnea report restless sleep, morning headaches, and excessive daytime sleepiness without realizing the underlying cause.

Central Sleep Apnea and Complex Sleep Apnea Syndrome

Central sleep apnea differs from the obstructive form because the airway is not physically blocked. Instead, the brain intermittently fails to send the correct signals to the muscles that control breathing. Cheyne-Stokes respiration, a pattern of gradually increasing and decreasing breathing effort, is a hallmark of central sleep apnea often seen in patients with heart failure. Complex sleep apnea syndrome, sometimes called treatment-emergent central sleep apnea, occurs when a patient has both obstructive and central components. This distinction matters because treatment approaches differ. CPAP therapy may resolve obstructive events but can sometimes unmask or worsen central apneas, requiring adaptive servo-ventilation or BiPAP with a backup rate.

Insomnia, Restless Legs Syndrome, and Movement Disorders

Insomnia is characterized by difficulty initiating or maintaining sleep despite adequate opportunity, with daytime consequences such as fatigue, poor concentration, and mood disturbance. Restless legs syndrome causes an uncomfortable urge to move the legs, typically worse at rest and in the evening, which disrupts sleep onset. Periodic limb movement disorder involves repetitive limb movements during sleep that cause arousals. REM sleep behavior disorder is a condition where normal muscle paralysis during REM sleep is absent, leading to physical acting out of dreams.

Hormonal Shifts, Perimenopause, and Sleep Disruptions

Sleep disruptions often intensify during hormonal shifts, including perimenopause. Fluctuations in estrogen and progesterone can worsen insomnia, increase the frequency of sleep-disordered breathing events, and alter circadian rhythm timing. According to the Sleep Foundation,women going through perimenopause are significantly more likely to develop or notice symptoms of obstructive sleep apnea. These hormonal changes also affect biomarkers like cortisol and DHEA-S, which Dumbo Health tracks as part of its sleep longevity biomarker panels.

Sleep Disorders and Comorbid Conditions

Chronic Obstructive Pulmonary Disease (COPD) frequently coexists with sleep apnea, a combination sometimes called overlap syndrome, which amplifies oxygen desaturation during sleep and increases cardiovascular strain. Patients with overlap syndrome require careful titration studies to balance positive airway pressure settings. Heart activity monitoring during sleep evaluations can reveal arrhythmias that are missed during daytime testing.

KEY TAKEAWAY: Philadelphia sleep specialists diagnose a wide spectrum of conditions beyond snoring, and the specific disorder you have determines the right diagnostic test, treatment, and whether biomarker monitoring could reveal hidden health risks.

Once you understand which conditions exist, the next question is how they are diagnosed.

How Sleep Testing Works: In-Lab Studies, Home Sleep Tests, and At-Home Options

Sleep testing is the diagnostic process that confirms or rules out a sleep disorder. The two primary approaches are in-lab polysomnography and home sleep testing. Each method captures different data, and the right choice depends on your suspected condition, medical history, and access to testing facilities.

Polysomnography: The In-Lab Sleep Study

Polysomnography is an overnight sleep study conducted in a sleep center or sleep lab under the supervision of a polysomnographic technologist or a registered polysomnography sleep technician. The study records brain waves using electroencephalography, eye movements, chin and leg muscle activity, heart activity via electrocardiogram, oxygen level through pulse oximetry, nasal and oral airflow, chest and abdominal respiratory effort, and body position. Philadelphia has multiple accredited sleep centers, including Penn Sleep Centers within the University of Pennsylvania Health System, as well as community-based facilities in Horsham, PA, Lancaster, and other clinic locations across Pennsylvania.

An in-lab study is typically required when the clinician suspects central sleep apnea, periodic limb movement disorder, REM sleep behavior disorder, complex sleep apnea syndrome, or when the clinical picture is complicated by conditions like COPD or heart failure. Titration studies, where positive airway pressure is adjusted during a second overnight study, are also performed in-lab.

Home Sleep Testing: A Practical Alternative

A home sleep test is a simplified diagnostic system that you use in your own bed. Devices like the ApneaLink and the WatchPAT record airflow, respiratory effort, oxygen level, and sometimes heart rate variability and body position. Home sleep testing is clinically validated for diagnosing obstructive sleep apnea in adults without significant comorbidities. The American Academy of Sleep Medicine supports home sleep testing when pre-test probability for obstructive sleep apnea is moderate to high and when there are no complicating conditions.

Home testing is more convenient, less expensive, and often produces results faster than in-lab polysomnography. Programs like the Sleep Disorder Associates Home Sleep Testing Program in the Philadelphia area use disposable device technology and cloud technology to transmit sleep data to physicians remotely. Patients in Pennsylvania, New Jersey, and beyond can access at-home sleep testing without visiting a clinic.

Dumbo Health offers an FDA-cleared at-home sleep apnea test for $149, with physician diagnosis typically within days. Available in Florida, Texas, Virginia, and Maryland. The test is one-time, all-inclusive, requires no insurance or prior authorization, and ships directly to you. For people exploring whether sleep apnea is affecting their biological aging, this test can serve as an entry point into the broader sleep longevity program, where results are paired with biomarker data and tracked through the SleepLongevityAge metric.

How to Get Tested: Step-by-Step Process

1. Evaluate your symptoms. Note whether you experience loud snoring, witnessed breathing pauses, restless sleep, daytime fatigue, or morning headaches.
2. Consult a sleep physician or your primary care provider. A referral is often needed for an in-lab study. For home sleep testing, many programs and Dumbo Health allow direct ordering without a referral in most states.
3. Choose your testing method. If you are an adult with a moderate to high likelihood of obstructive sleep apnea and no significant comorbidities, a home sleep test is usually appropriate. If central sleep apnea, a movement disorder, or complex medical history is suspected, an in-lab polysomnography is recommended.
4. Complete the test. For home testing, follow the device instructions, sleep with the sensors attached for one or two nights, and return or upload the data. For in-lab testing, check in at the sleep center and spend the night under technician supervision.
5. Receive your results. Home test results are typically available within days to one week. In-lab studies may take one to two weeks, depending on the facility. Dumbo Health provides physician-reviewed results within days for its at-home test.
6. Review your diagnosis and treatment plan with your physician, who will recommend next steps based on the severity and type of sleep disorder identified.

After completing testing, you will have a clear diagnosis and can move into the treatment phase.

DID YOU KNOW: According to the American Academy of Sleep Medicine, approximately 80 percent of moderate to severe obstructive sleep apnea cases remain undiagnosed, making accessible home testing a critical tool for closing the diagnostic gap.

KEY TAKEAWAY: Home sleep testing is a validated, convenient, and lower-cost alternative to in-lab polysomnography for most adults suspected of having obstructive sleep apnea, and programs like Dumbo Health deliver results within days for $149 with no insurance required.

With a diagnosis in hand, the next decision is which treatment approach fits your specific condition and lifestyle.

Sleep Apnea Treatments: CPAP, BiPAP, Oral Appliance Therapy, and Beyond

CPAP therapy is the first-line treatment for moderate to severe obstructive sleep apnea, but it is not the only option. Treatment choice depends on the type and severity of your sleep disorder, your anatomy, your tolerance for different devices, and your long-term goals.

CPAP Therapy

A CPAP machine delivers continuous positive airway pressure through a mask worn during sleep. The air pressure acts as a pneumatic splint, keeping the airway open and preventing the collapses that cause apneas and hypopneas. According to the American Academy of Sleep Medicine, CPAP therapy reduces the apnea-hypopnea index (AHI), improves oxygen saturation, lowers blood pressure, and reduces daytime sleepiness when used consistently.

Adherence is the most important factor in CPAP therapy success. The clinical benchmark is at least 4 hours per night on at least 70 percent of nights. Many insurance providers use this threshold to determine continued coverage. Equipment education, proper mask fitting, and ongoing support improve compliance. Manufacturers like ResMed produce a range of devices, including the Dreamstation AutoCPAPs and the AirSense series, with auto-titrating features that adjust pressure in real time. Facilities in the Philadelphia area, including Penn Sleep Centers, offer structured CPAP Programs with equipment education and follow-up.

Dumbo Health includes CPAP prescription, equipment, and ongoing resupply as part of its active clinical care for members diagnosed with sleep apnea through the platform. Telehealth clinical support is currently available in Florida, Texas, Virginia, and Maryland, the same four states the at-home sleep apnea test ships to. For Philadelphia residents, this means you can complete the diagnostic process through Dumbo Health and receive CPAP equipment with physician oversight, while also tracking how CPAP therapy changes your sleep-related biomarkers over time through the sleep longevity membership.

BiPAP and Adaptive Ventilation

BiPAP (bilevel positive airway pressure) delivers two different pressure levels: higher pressure during inhalation and lower pressure during exhalation. BiPAP is prescribed when CPAP alone is not tolerated, when high pressures are needed, or for patients with central sleep apnea, Cheyne-Stokes respiration, or overlap syndrome with Chronic Obstructive Pulmonary Disease. Astral ventilators and adaptive servo-ventilation devices represent more advanced breathing devices used in the Sleep Ventilation Program for patients with complex respiratory and sleep-disordered breathing.

Oral Appliance Therapy

Oral appliance therapy uses a custom-fitted device made by a sleep dentist to reposition the lower jaw forward during sleep, widening the airway. It is recommended for mild to moderate obstructive sleep apnea or for patients who cannot tolerate CPAP. The American Academy of Sleep Medicine recommends oral appliances as a first-line option for mild obstructive sleep apnea and as an alternative for moderate to severe cases when CPAP is not feasible.

Positional Therapies and Surgical Options

Positional therapies address supine-predominant obstructive sleep apnea by encouraging side sleeping. These range from wearable devices to specialized pillows. Sleep Surgery, including procedures performed at Penn Sleep Surgery within the University of Pennsylvania Health System, may be considered for patients with anatomical airway obstruction who do not respond to conservative treatments. Surgical options include uvulopalatopharyngoplasty, maxillomandibular advancement, hypoglossal nerve stimulation, and, in cases of obesity-related sleep apnea, bariatric procedures offered through programs like the Temple Bariatric Program.

Comparing Treatment Options

Here is how the primary treatment approaches compare across key factors:

Effectiveness for Moderate to Severe OSA

• CPAP Therapy: Gold standard, reduces AHI by 80 percent or more with consistent use
• BiPAP: Comparable to CPAP for obstructive events, preferred for central or complex apnea
• Oral Appliance Therapy: Effective for mild to moderate OSA, less effective for severe cases

Convenience

• CPAP Therapy: Requires nightly mask wear, machine, and power source
• BiPAP: Same logistics as CPAP with additional settings complexity
• Oral Appliance Therapy: Small, portable custom-fitted device with no power needed

Cost

• CPAP Therapy: Typically $250 to $1,000 for the machine plus ongoing resupply; Dumbo Health includes equipment and resupply in active clinical care. These are offered in Florida, Texas, Virginia, and Maryland.
• BiPAP: Typically $1,500 to $3,500 depending on features
• Oral Appliance Therapy: Typically $1,500 to $3,000 for fabrication and fitting by a sleep dentist

Best For

• CPAP Therapy: Moderate to severe obstructive sleep apnea with consistent nightly use
• BiPAP: Central sleep apnea, complex sleep apnea syndrome, or CPAP intolerance
• Oral Appliance Therapy: Mild to moderate obstructive sleep apnea or CPAP-intolerant patients

For most adults with moderate to severe obstructive sleep apnea, CPAP therapy remains the recommended first-line treatment due to its established effectiveness and the volume of supporting evidence.

KEY TAKEAWAY: CPAP therapy is the most effective treatment for moderate to severe obstructive sleep apnea, but oral appliance therapy, BiPAP, positional therapies, and surgery provide viable alternatives depending on severity, anatomy, and patient preference.

Knowing your treatment options is important, but choosing the right sleep specialist or clinic in Philadelphia determines the quality of care you receive.

Finding a Sleep Specialist in Philadelphia: Where to Start and What to Look For

The right sleep specialist in Philadelphia will be fellowship-trained in sleep medicine, credentialed at an accredited sleep center, and equipped to offer both diagnostic testing and ongoing treatment management. Philadelphia and the surrounding Pennsylvania region have several respected sleep medicine programs, ranging from academic medical centers to community practices.

Major Sleep Centers and Practices in the Philadelphia Area

Penn Sleep Centers, part of the University of Pennsylvania Health System, operate multiple clinic locations across the Philadelphia region and offer comprehensive sleep evaluations, in-lab polysomnography, home sleep testing, CPAP therapy, BiPAP, oral appliance therapy coordination, and sleep surgery consultations through Penn Sleep Surgery. The sleep team at Penn includes fellowship-trained physicians like Ron Anafi and other specialists with DABSM certification.

Sleep Disorder Associates is a community-based practice offering sleep diagnostics, including the Sleep Disorder Associates Home Sleep Testing Program, which uses the ApneaLink device for at-home sleep testing. The practice has served patients in the Philadelphia area for years and provides an accessible option for patients who prefer a smaller practice setting.

Mercado Medical Practice, Ochsner Rush Sleep Center (for patients who travel or have connections to the broader health network), and providers affiliated with the Philadelphia College of Osteopathic Medicine offer additional pathways. Specialists like Dr. Funke Afolabi-Brown (a pediatric and adult sleep physician noted for sleep health education), Dr. Neil Kline, Maria Antoniou, Yana Sigal Banerjee, Charles Bae, Sarah Beck, Janice Franks Biddle, and Sara Cadman represent the diversity of sleep medicine expertise available in the region. Some hold AGPCNP-BS or CRNP credentials and work alongside physicians in collaborative care models.

Philadelphia Magazine publishes a curated list of Top Doctors in partnership with Castle Connolly Medical Ltd., a healthcare researcher that evaluates physician credentials, training, and peer recognition. Sleep medicine specialists from the Philadelphia area appear on this list alongside providers in dermatology, cardiology, and orthopedics. While appearing on a best doctors list is one data point, the most reliable indicators of quality are board certification in sleep medicine (DABSM), accreditation of the sleep center by the American Academy of Sleep Medicine, and the breadth of diagnostic and treatment services offered.

What to Look For in a Sleep Specialist

Checklist: Evaluating a Sleep Specialist in Philadelphia

• Confirm the physician is fellowship-trained in sleep medicine with DABSM certification
• Verify the sleep center is accredited by the American Academy of Sleep Medicine
• Ask whether the practice offers both in-lab polysomnography and home sleep testing
• Confirm whether CPAP equipment education, mask fitting, and follow-up are included in the program

Telehealth and Remote Sleep Medicine in Pennsylvania

Telehealth has expanded access to sleep medicine consultations significantly across Pennsylvania. Many sleep specialists in Philadelphia now offer telehealth appointments for initial evaluations, follow-up visits, CPAP adherence reviews, and results discussions. This is particularly valuable for patients in Lancaster, Horsham, PA, or other areas outside central Philadelphia who may not have a fellowship-trained sleep physician near them.

Dumbo Health's platform leverages telehealth for clinical consultations, currently offering full telehealth clinical support in Florida, Texas, Virginia, and Maryland, the same four states the at-home sleep apnea test ships to. Pennsylvania residents can access at-home sleep apnea testing and biomarker blood draws through the Quest Diagnostics testing network, with roughly 9 in 10 people living within 20 minutes of a draw location.

If you suspect a sleep disorder, do not delay evaluation. Untreated sleep apnea and chronic insomnia have cumulative effects on cardiovascular health, metabolic function, and cognitive performance that worsen over time.

KEY TAKEAWAY: Look for fellowship-trained, DABSM-certified sleep specialists at accredited centers, and consider telehealth options and biomarker-driven programs like Dumbo Health to extend your care beyond the clinic visit.

Finding the right specialist is one step, but understanding how sleep quality connects to biological aging adds a dimension most traditional sleep clinics do not address.

Sleep as a Driver of Biological Aging: The Science Behind SleepLongevityAge

Poor sleep quality accelerates biological aging by disrupting the physiological processes that repair cells, regulate inflammation, and maintain metabolic balance. This connection is why Dumbo Health built its sleep longevity membership around a proprietary metric called SleepLongevityAge.

Biological age reflects the functional state of your body at the cellular and molecular level, as opposed to chronological age, which simply counts years since birth. The National Institute on Aging explains that biological age is influenced by genetics, lifestyle, environmental exposures, and, critically, sleep. Two people who are both 48 years old chronologically may have biological ages that differ by a decade or more depending on their sleep quality, metabolic health, and inflammatory burden.

Sleep deprivation and sleep fragmentation increase hs-CRP (a marker of systemic inflammation), elevate cortisol (the primary stress hormone), impair glucose regulation (reflected in HbA1c levels), and raise ApoB (a key cardiovascular risk marker). According to research cited by the NIH, chronic short sleep (less than 6 hours per night) is associated with accelerated telomere shortening, one of the hallmarks of cellular aging. Heart rate variability (HRV), a measure of autonomic nervous system flexibility, also declines with poor sleep and correlates with biological age estimates.

SleepLongevityAge is Dumbo Health's proprietary metric that synthesizes blood biomarker data with optional wearable data from devices like Oura, Whoop, and Garmin. The score is reviewed by board-certified physicians and tracked over time, giving you a longitudinal view of how your sleep habits and treatments are moving your biological age up or down. The Core membership tests 51 sleep-longevity biomarkers twice a year. The Concierge membership expands to 103 biomarkers, adds a dedicated sleep physician with 24/7 access, and includes a personal sleep coach.

SleepLongevityAge connects clinical sleep data (apnea-hypopnea index, oxygen desaturation index, total sleep time, sleep stage distribution) with blood biomarkers (inflammation, metabolic, hormonal, cardiovascular, and longevity markers) to produce a single metric. SleepLongevityAge is designed to quantify the relationship between sleep quality and biological aging, giving individuals and their physicians a measurable way to track improvement or decline. No other consumer-facing sleep program integrates this breadth of clinical and biomarker data into a single age metric.

TIP: If you use a wearable device like Oura, Whoop, or Garmin, you can integrate your sleep data into the Dumbo Health platform to enrich your SleepLongevityAge score with continuous sleep stage, HRV, and respiratory rate data.

KEY TAKEAWAY: Sleep is not just about feeling rested; poor sleep measurably accelerates biological aging through inflammation, metabolic dysfunction, and cardiovascular strain, which is exactly what SleepLongevityAge is designed to track.

Understanding how sleep shapes biological age naturally leads to the question of what you can actually measure and monitor.

Biomarker Testing for Sleep and Longevity: What Gets Measured and Why

Biomarker testing for sleep longevity measures the blood-level indicators most sensitive to sleep disruption, metabolic health, hormonal balance, and cardiovascular risk. These markers reveal damage and risk that symptoms alone cannot capture.

Dumbo Health's biomarker panels are built specifically around the markers most relevant to sleep-driven biological aging. The Core plan includes 51 sleep-longevity biomarkers drawn twice a year. Key markers include:

• HbA1c: reflects average blood glucose over the preceding 2 to 3 months. Chronic sleep loss impairs insulin sensitivity and raises HbA1c, increasing the risk of type 2 diabetes.
• hs-CRP: a high-sensitivity marker of systemic inflammation. Elevated hs-CRP is associated with sleep apnea severity, cardiovascular risk, and accelerated biological aging.
• Cortisol: the primary stress hormone. Disrupted sleep elevates cortisol, particularly in the early morning, with downstream effects on immune function and metabolism.
• ApoB: a lipoprotein particle that carries cholesterol into arterial walls. Elevated ApoB is a stronger predictor of cardiovascular events than LDL cholesterol alone.
• GFR (glomerular filtration rate): a measure of kidney function that can decline with chronic inflammation and metabolic stress.
• Testosterone and DHEA-S: hormones that decline with poor sleep and aging. The Hormone and Vitality add-on pack ($99) covers testosterone variants, DHEA-S, and menopause-related markers.

Add-on specialty packs expand the panel for specific concerns:

• Metabolic and Appetite ($99): C-peptide, leptin, GGT
• Advanced Longevity ($99): Omega-3 Index, RBC magnesium, key fatty acids
• Circadian and Stress ($269): morning cortisol plus a 4-point salivary cortisol curve
• Cardiac Strain ($429): NT-proBNP, high-sensitivity troponin
• Biological Age ($499, coming soon): epigenetic clock and telomere length

Blood draws are completed through the Quest Diagnostics network, with more than 2,000 locations nationwide. Roughly 9 in 10 people live within 20 minutes of a Quest location, making it easy to find a testing location near you. In-home mobile phlebotomist draws are available in select states. Results typically come back in about 7 days.

For Philadelphia residents, this means you can complete a biomarker draw at a Quest Diagnostics location in your area, receive results within a week, and have your SleepLongevityAge score reviewed by a board-certified physician through the Dumbo Health platform.

The Concierge plan at $300 a month for early members ($3,600 a year) includes 103 biomarkers tested twice a year, covering every specialty marker, a dedicated sleep physician with 24/7 access, a personal sleep coach, and all add-on packs included. The Core plan at $0.99 a day for early members ($365 a year) is designed for people who want a reliable baseline with physician support when needed. Both plans are HSA and FSA eligible, require no insurance, and carry no prior authorizations or surprise bills. Early-member pricing locks for life for the first 500 members. You can explore membership plans and pricing on the Dumbo Health site.

KEY TAKEAWAY: Biomarker testing quantifies the invisible health effects of poor sleep, and Dumbo Health's panels are purpose-built around the markers most relevant to sleep-driven biological aging, available at Quest Diagnostics locations close to you across Pennsylvania and 48 other states.

Biomarkers tell you what is happening inside your body, but real-world scenarios show how different people use this information.

Real-World Scenarios: How Different People Use Sleep Specialists and Longevity Testing

Sleep disorders and their long-term health effects look different depending on age, medical history, and health goals. The following scenarios illustrate how clinical sleep care and biomarker-driven longevity testing work in practice.

Common Scenarios

A 42-year-old marketing director in Philadelphia has been told by her partner that she snores loudly and sometimes stops breathing during the night. She is gaining weight, her blood pressure has crept up, and she wakes up with headaches. Her primary care physician refers her to Penn Sleep Centers for evaluation. A home sleep test using the ApneaLink device reveals moderate obstructive sleep apnea with an AHI of 22. She begins CPAP therapy with a Dreamstation AutoCPAP and follows up with her sleep team via a telehealth appointment. After 3 months of consistent use, her daytime sleepiness resolves. She wants to go further and enrolls in the Dumbo Health Core plan. Her first biomarker draw at a Quest location in Philadelphia shows elevated hs-CRP and HbA1c. Six months later, after consistent CPAP use, her repeat biomarker draw shows both markers trending downward. Her SleepLongevityAge drops by 2 years.

A 55-year-old truck driver from Lancaster, Pennsylvania, needs to maintain his commercial driver's license. His DOT medical examiner flags his BMI and neck circumference as risk factors for obstructive sleep apnea and requires a sleep test. He orders Dumbo Health's $149 at-home sleep apnea test, completes it at home over one night, and receives a diagnosis of severe obstructive sleep apnea within days. Available in Florida, Texas, Virginia, and Maryland. He is prescribed CPAP through the program and begins treatment. Because his livelihood depends on maintaining his medical certificate, he also enrolls in the Core membership to monitor how his cardiovascular and metabolic markers respond to treatment over time. His sleep data and biomarker results give him documentation of compliance and health improvement that supports his DOT renewal.

A 48-year-old executive in Horsham, PA, uses an Oura ring and notices her deep sleep percentage has been declining steadily over the past year. She does not snore, and her Oura scores flag no breathing disturbances, but she feels cognitively slower and her recovery scores are poor. She suspects hormonal shifts related to perimenopause. She joins the Dumbo Health Concierge plan, which gives her access to 103 biomarkers including hormonal panels. Her results show low DHEA-S, elevated cortisol, and borderline HbA1c. Her dedicated sleep physician reviews her wearable data alongside her blood work and identifies a circadian rhythm misalignment contributing to poor deep sleep. A targeted intervention plan is created. This is a scenario where a traditional sleep center might not have caught the problem, because no single sleep disorder explains her symptoms, but the biomarker data combined with wearable sleep data reveals the pattern.

KEY TAKEAWAY: Real-world scenarios show that sleep problems rarely exist in isolation. Combining clinical sleep evaluation with biomarker tracking provides a more complete and actionable picture than either approach alone.

These examples show what is possible, but it is equally important to understand where sleep longevity testing has limitations.

Limitations and Risks: When Sleep Specialist Care or Longevity Testing May Not Be the Right Fit

No single approach to sleep health works for every person. Clinical sleep evaluation, CPAP therapy, and biomarker-driven longevity testing each have specific limitations that are important to understand before committing.

Home sleep testing is validated for obstructive sleep apnea in adults but is not appropriate for diagnosing central sleep apnea, REM sleep behavior disorder, periodic limb movement disorder, or narcolepsy. These conditions require in-lab polysomnography with full EEG monitoring. If your clinician suspects a non-obstructive or neurological sleep disorder, a home test will miss critical data. According to the American Academy of Sleep Medicine, home sleep testing can underestimate AHI in some patients, which means a negative home test does not always rule out sleep apnea.

CPAP therapy works only if you use it. Adherence rates are a significant concern. The Sleep Foundation reports that roughly 50 percent of patients prescribed CPAP discontinue use within the first year. Without consistent adherence, the cardiovascular, metabolic, and cognitive benefits of CPAP do not materialize. Equipment education, mask fitting, and ongoing follow-up are essential. Dumbo Health helps mitigate this by providing ongoing clinical support, equipment resupply, and telehealth follow-up as part of active clinical care, but adherence ultimately depends on the patient. Available in Florida, Texas, Virginia, and Maryland.

Biomarker testing through Dumbo Health shows trends in markers associated with sleep and biological aging, but it does not diagnose diseases on its own. Elevated hs-CRP, for example, is associated with systemic inflammation but can be caused by infection, autoimmune conditions, or recent injury rather than sleep disruption specifically. Results should always be interpreted by a physician in the context of your full medical history. Dumbo Health provides physician review and personalized fix plans, but complex cases may require referral to a local specialist. Available in Florida, Texas, Virginia, and Maryland.

SleepLongevityAge is a composite metric designed to track trajectory over time. A single score provides a baseline but is most useful when measured longitudinally across at least two draws. Expecting a life-changing insight from a single test is unrealistic. The power is in the trend.

Dumbo Health's telehealth clinical support is currently available in Florida, Texas, Virginia, and Maryland for sleep apnea management. Philadelphia residents can access diagnostic testing and biomarker panels through the platform, but full telehealth clinical follow-up for CPAP management may require coordination with a local sleep physician until Pennsylvania telehealth coverage expands.

Pediatric sleep evaluations require specialized expertise and are beyond the scope of most home testing programs. If a child in the Philadelphia area has suspected sleep-disordered breathing, a referral to a fellowship-trained pediatric sleep specialist such as Dr. Funke Afolabi-Brown or a pediatric sleep center is appropriate.

Dumbo Health's Sleep Longevity biomarker membership is available in every state except Rhode Island. At-home sleep apnea testing and CPAP care are offered in Florida, Texas, Virginia, and Maryland. Pricing in New York and New Jersey may differ due to state lab regulations. These are practical limitations to verify before enrolling.

KEY TAKEAWAY: Home sleep tests, CPAP therapy, and biomarker-based longevity programs are powerful tools but have defined boundaries. Understanding these limitations helps you set realistic expectations and get the most value from each service.

With the limitations in view, it is worth addressing some of the most common misconceptions that lead people to delay care or choose the wrong approach.

Common Myths About Sleep Specialists and Sleep Longevity Debunked

MYTH: You only need a sleep specialist if you snore.

FACT: Snoring is one symptom of obstructive sleep apnea, but sleep specialists diagnose and treat more than 80 distinct sleep disorders. Conditions like insomnia, restless legs syndrome, REM sleep behavior disorder, and circadian rhythm disorders do not involve snoring at all. According to the American Academy of Sleep Medicine, many patients with significant sleep apnea do not report snoring as a primary symptom. Daytime fatigue, morning headaches, and restless sleep are equally important warning signs.

MYTH: A sleep study requires spending a night in a hospital.

FACT: Home sleep testing is a validated alternative for diagnosing obstructive sleep apnea in adults. Devices like the ApneaLink are worn at home and record airflow, oxygen level, and respiratory effort. Dumbo Health offers a $149 at-home sleep apnea test that provides physician-reviewed results within days. Available in Florida, Texas, Virginia, and Maryland. In-lab polysomnography is reserved for suspected central sleep apnea, movement disorders, or complex cases where full monitoring is clinically necessary.

MYTH: CPAP is the only treatment for sleep apnea.

FACT: CPAP is the first-line treatment for moderate to severe obstructive sleep apnea, but alternatives exist. Oral appliance therapy, BiPAP, positional therapies, and sleep surgery are all recognized options depending on apnea severity, anatomy, and patient tolerance. The American Academy of Sleep Medicine recommends oral appliances as a first-line option for mild obstructive sleep apnea.

MYTH: Sleep quality does not affect aging.

FACT: Chronic poor sleep is associated with elevated inflammatory markers, impaired glucose metabolism, increased cardiovascular risk, and accelerated telomere shortening according to the NIH. Biological age, measured through biomarkers and epigenetic clocks, can diverge from chronological age based on sleep quality. Dumbo Health's SleepLongevityAge metric tracks this relationship directly through 51 to 103 blood biomarkers tested twice a year.

MYTH: Wearable devices like Oura or Whoop can diagnose sleep apnea.

FACT: Consumer wearable devices track sleep stages, heart rate variability, and respiratory rate with increasing accuracy, but they are not FDA-cleared diagnostic tools for sleep apnea. A clinical sleep test (either in-lab polysomnography or an FDA-cleared home sleep test) is required for a formal diagnosis. Wearable data can complement clinical findings and is integrated into the Dumbo Health platform to enrich the SleepLongevityAge score, but it does not replace medical testing.

KEY TAKEAWAY: Misconceptions about sleep medicine delay diagnosis and treatment. Understanding what is myth and what is fact helps you take the right steps at the right time, whether that means getting a clinical test, starting treatment, or tracking how sleep affects your biological age.

Now that the myths are cleared, here is a practical overview of how to take your next step.

Frequently Asked Questions About Sleep Specialists in Philadelphia

What is a sleep specialist and what do they treat?

A sleep specialist is a physician trained in diagnosing and managing conditions that affect sleep quality, duration, and breathing during sleep. Sleep specialists in Philadelphia commonly treat obstructive sleep apnea, central sleep apnea, insomnia, restless legs syndrome, periodic limb movement disorder, REM sleep behavior disorder, circadian rhythm disorders, and complex sleep apnea syndrome. Some sleep specialists also support patients with conditions such as Chronic Obstructive Pulmonary Disease that interact with sleep-disordered breathing. A referral is not always required, but a healthcare professional can help determine whether a sleep specialist evaluation is the right next step for your symptoms.

What is sleep apnea?

Sleep apnea is a condition in which breathing repeatedly stops and starts during sleep. The most common form is obstructive sleep apnea, which occurs when the upper airway collapses or becomes blocked during sleep, reducing or completely stopping airflow. Central sleep apnea occurs when the brain fails to send proper signals to the breathing muscles. According to the American Academy of Sleep Medicine, obstructive sleep apnea is associated with increased risk of high blood pressure, cardiovascular disease, metabolic problems, and daytime impairment. Many people with sleep apnea are unaware they have it. A sleep physician can evaluate symptoms such as snoring, gasping, pauses in breathing, and excessive daytime sleepiness.

What is snoring and when does it become a health concern?

Snoring is the sound produced when airflow causes the soft tissues of the upper airway to vibrate during sleep. It is common and does not always indicate a medical problem. However, snoring can be a symptom of obstructive sleep apnea, particularly when accompanied by pauses in breathing, choking or gasping during the night, restless sleep, or daytime sleepiness. The Sleep Foundation notes that habitual snoring affects a significant portion of adults and is more common in people with excess body weight, a large neck circumference, nasal congestion, or structural airway issues. If snoring is frequent and disruptive, a sleep evaluation is a reasonable step.

What causes snoring?

Snoring occurs when the muscles of the throat relax during sleep, narrowing the airway and causing surrounding tissue to vibrate as air passes through. Common contributing factors include excess body weight, alcohol consumption before bed, nasal congestion, sleeping position, enlarged tonsils or adenoids, and anatomical features such as a low soft palate or elongated uvula. In some people, snoring is position-dependent and improves with positional therapies. In others, it reflects ongoing airway obstruction that may require clinical evaluation. A sleep physician can assess whether snoring reflects a primary snoring condition or an underlying disorder such as obstructive sleep apnea.

What is obstructive sleep apnea and how is it different from central sleep apnea?

Obstructive sleep apnea is caused by a physical collapse or narrowing of the upper airway during sleep, which reduces or stops breathing despite continued breathing effort. Central sleep apnea occurs when the brain does not send appropriate signals to the breathing muscles, so no breathing effort is made. Complex sleep apnea syndrome is a combination of both. Each type requires different clinical evaluation and treatment approaches. Obstructive sleep apnea is the most prevalent form, and the American Academy of Sleep Medicine estimates that approximately one billion people between the ages of 30 and 69 worldwide may have some degree of the condition. A sleep physician can determine which type is present based on sleep study data.

Why might I benefit from a sleep test?

A sleep test can help determine whether your sleep symptoms are caused by a diagnosable sleep disorder. Common reasons to consider a sleep evaluation include loud or frequent snoring, observed pauses in breathing during sleep, waking up choking or gasping, unrefreshing sleep, morning headaches, excessive daytime sleepiness, difficulty concentrating, or high blood pressure that is difficult to control. Sleep testing measures variables including breathing patterns, oxygen saturation, airflow, heart activity, and body movements during sleep. A healthcare professional can help decide whether a home sleep test or an in-lab study is the more appropriate option for your situation.

What types of sleep disorders can a sleep test detect?

A sleep study can detect a range of sleep disorders depending on the type of test used. A home sleep apnea test is designed primarily to detect obstructive sleep apnea by measuring airflow, breathing effort, oxygen levels, and hypopneas. An in-lab polysomnography study measures a broader range of signals including brain waves, eye movements, heart activity, muscle activity, and oxygen saturation, which allows clinicians to evaluate conditions such as REM sleep behavior disorder, periodic limb movement disorder, central sleep apnea, Cheyne-Stokes respiration, restless legs syndrome, and circadian rhythm disorders. A sleep physician determines which type of study is appropriate based on symptoms and clinical history.

Who can benefit most from a sleep test?

People who are most likely to benefit from a sleep test include those with persistent snoring, witnessed breathing pauses during sleep, nighttime gasping or choking, unrefreshing sleep, excessive daytime sleepiness, or unexplained high blood pressure. Adults with obesity, a large neck circumference, or a family history of sleep apnea are at higher risk. Midlife women experiencing hormonal shifts during perimenopause may also be candidates, as hormonal changes can increase sleep apnea risk and worsen sleep disruptions. Children with behavioural problems, poor growth, or suspected airway issues may also benefit. A sleep specialist can assess whether testing is appropriate based on individual risk factors and symptoms.

How is sleep apnea diagnosed?

Sleep apnea is diagnosed through a sleep study that measures breathing during sleep. The two main types of testing are a home sleep apnea test and an in-lab polysomnography study. A home sleep test typically measures airflow, breathing effort, oxygen saturation, and the apnea-hypopnea index, which counts the average number of apneas and hypopneas per hour. Polysomnography, conducted in a sleep center by a registered polysomnographic technologist, measures a broader set of signals including brain waves, heart activity, and muscle movements. A sleep physician interprets the results and confirms or rules out a diagnosis. A diagnosis of sleep apnea requires clinical interpretation and cannot be made from symptoms alone.

Will I need to have my sleep test done in a lab, or can it be done at home?

Both options exist. A home sleep apnea test allows you to sleep in your own bed while a small, FDA-cleared device records your breathing patterns, oxygen levels, and airflow during the night. Home testing is appropriate for many adults with a moderate to high probability of obstructive sleep apnea. An in-lab polysomnography study is conducted in a sleep center and is more comprehensive, capturing brain waves, eye movements, limb movements, heart activity, and additional variables. A sleep physician determines which type of study is appropriate. Some complex cases, including suspected central sleep apnea, REM sleep behavior disorder, or periodic limb movement disorder, typically require in-lab testing for accurate diagnosis. Dumbo Health offers a $149 at-home sleep apnea test for those who prefer testing in their own home. Available in Florida, Texas, Virginia, and Maryland.

What is oral appliance therapy for sleep apnea?

Oral appliance therapy is a non-CPAP treatment for obstructive sleep apnea that uses a custom-fitted device worn in the mouth during sleep. The device repositions the jaw or tongue to keep the upper airway open and reduce breathing interruptions. It is typically fitted and managed by a sleep dentist and is an option for patients with mild to moderate obstructive sleep apnea who cannot tolerate CPAP therapy. Oral appliances are generally considered more comfortable and portable than CPAP machines, though they may be less effective for severe sleep apnea. A sleep physician and sleep dentist work together to assess whether oral appliance therapy is appropriate and to monitor treatment outcomes.

How much does an oral appliance for sleep apnea cost?

Oral appliance costs vary depending on the provider, the device design, and whether insurance covers the treatment. Custom-fitted oral appliances typically range from several hundred to over two thousand dollars out of pocket when paying privately. Some insurance plans cover oral appliance therapy when sleep apnea has been clinically diagnosed and documented. If you are paying out of pocket, confirm the total cost with your provider before treatment begins, including any charges for digital impressions, follow-up adjustments, and replacement devices. A sleep physician or sleep dentist can advise whether oral appliance therapy is clinically appropriate and what out-of-pocket costs to expect.

What is CPAP therapy and how does it work?

CPAP, which stands for continuous positive airway pressure, is the most widely used treatment for obstructive sleep apnea. A CPAP machine delivers a continuous stream of pressurised air through a mask worn over the nose, mouth, or both during sleep. This air pressure acts as a pneumatic splint that keeps the upper airway open, preventing the collapses that cause apneas and hypopneas. The American Academy of Sleep Medicine supports CPAP as the primary recommended treatment for moderate to severe obstructive sleep apnea. BiPAP, which delivers two pressure levels for inhalation and exhalation, is an alternative used in some cases. CPAP prescription and device selection require clinician guidance.

What happens if sleep apnea is left untreated?

Untreated obstructive sleep apnea is associated with a range of health risks. According to the National Heart, Lung, and Blood Institute, sleep apnea has been linked to increased risk of high blood pressure, heart disease, stroke, type 2 diabetes, and cognitive impairment. Repeated drops in oxygen saturation during apnea events place strain on the cardiovascular system over time. Daytime sleepiness from fragmented sleep can also impair concentration, reaction time, and driving safety. These risks vary based on severity of the condition, individual health factors, and duration of untreated disease. A healthcare professional can help explain what untreated sleep apnea may mean for your individual health.

Do sleep specialists in Philadelphia see both children and adults?

Some sleep medicine practices in Philadelphia see both pediatric and adult patients, while others specialise in one population. Children can experience sleep-disordered breathing, obstructive sleep apnea, restless legs syndrome, parasomnias, and behavioural sleep problems, all of which may warrant evaluation by a sleep specialist with pediatric expertise. It is worth confirming when booking an appointment whether the practice or individual clinician has experience evaluating and treating children. Telehealth appointments are offered by some Philadelphia-area sleep practices and may be an option depending on your location and the type of evaluation needed.

Do sleep specialists in Philadelphia offer telehealth appointments?

Many sleep medicine practices in Philadelphia offer telehealth appointments for consultations, follow-up care, and CPAP management. Telehealth visits can be useful for initial symptom reviews, discussing sleep test results, managing ongoing treatment, and addressing adherence questions without requiring an in-person visit. Home sleep testing combined with telehealth consultation allows some patients to complete an evaluation entirely from home. Availability of telehealth services varies by practice and by state. It is worth confirming whether telehealth appointments are available for new patients and whether the clinician is licensed to provide care in your state before booking.

How do I find a sleep specialist near me in Philadelphia?

Sleep specialists in Philadelphia practice within hospital-affiliated sleep centers, academic medical centers, and independent sleep medicine clinics across the city and surrounding Pennsylvania communities. Many practices offer online scheduling, and some allow you to book a free initial consultation to determine whether a full evaluation makes sense. If you are considering biomarker-based sleep health testing or a home sleep apnea test without visiting a clinic, find a testing location near you through Dumbo Health, which supports at-home sleep apnea testing and biomarker blood draws at nearby lab locations. A healthcare professional can help determine whether in-person or remote care is more appropriate for your situation.

What is a polysomnography study and how does it differ from a home sleep test?

Polysomnography is an in-lab sleep study conducted in a clinical setting by a registered polysomnographic technologist. It records brain waves, eye movements, heart activity, oxygen saturation, airflow, breathing effort, and limb movements simultaneously throughout a full night of sleep. This comprehensive diagnostic system allows clinicians to detect a wide range of sleep disorders beyond obstructive sleep apnea. A home sleep apnea test is a simpler, portable diagnostic tool that typically measures airflow, breathing effort, oxygen saturation, and heart rate. Home tests are appropriate for many patients with suspected obstructive sleep apnea but are not suitable for evaluating complex conditions such as REM sleep behavior disorder, periodic limb movement disorder, or central sleep apnea.

What is the apnea-hypopnea index and what do the results mean?

The apnea-hypopnea index, commonly called the AHI, measures the average number of apneas and hypopneas per hour of sleep. An apnea is a complete pause in breathing lasting at least ten seconds. A hypopnea is a partial reduction in airflow accompanied by a drop in oxygen saturation or an arousal from sleep. The American Academy of Sleep Medicine uses the AHI to classify sleep apnea severity: fewer than five events per hour is generally considered normal in adults, five to fourteen is mild, fifteen to twenty-nine is moderate, and thirty or more is severe. A sleep physician interprets AHI results in the context of your oxygen levels, symptoms, and overall health to determine the appropriate treatment plan.

Can women and midlife adults develop sleep apnea?

Yes. Obstructive sleep apnea affects both men and women, though it is historically underdiagnosed in women. Hormonal shifts during perimenopause and menopause can reduce the protective effects of progesterone and estrogen on upper airway muscle tone, increasing sleep apnea risk in midlife women. Women with sleep apnea may also present with different symptoms than men, including insomnia, restless sleep, fatigue, and mood changes rather than the classic pattern of loud snoring and witnessed apneas. The National Heart, Lung, and Blood Institute recognises that sleep apnea risk increases with age and hormonal changes. A sleep specialist can assess whether symptoms in midlife women warrant a sleep evaluation.

What is restless legs syndrome and can a sleep specialist help?

Restless legs syndrome is a neurological condition characterised by an uncomfortable urge to move the legs, typically worse at rest and in the evening, which can significantly disrupt the ability to fall or stay asleep. It is classified as a sleep disorder and can also occur alongside periodic limb movement disorder, where the legs move involuntarily during sleep. Sleep specialists in Philadelphia who cover a broad range of sleep disorders are equipped to evaluate, diagnose, and manage restless legs syndrome. Treatment may include lifestyle changes, iron supplementation if deficiency is present, or medication, depending on severity and individual health. A healthcare professional can confirm whether restless legs syndrome is contributing to your sleep difficulties.

Does insurance cover sleep testing and treatment in Philadelphia?

Many insurance plans, including those common in Pennsylvania and the Philadelphia area, cover sleep testing and CPAP therapy when sleep apnea has been clinically documented and medical necessity has been established. Coverage details vary significantly between plans, and some require prior authorisation before approving a sleep study or CPAP equipment. For patients who prefer not to navigate insurance or who lack coverage, cash-pay options are available. Dumbo Health offers a $149 at-home sleep apnea test with transparent, cash-pay pricing, no insurance required, and no prior authorisations. Available in Florida, Texas, Virginia, and Maryland. All Dumbo Health membership plans are HSA and FSA eligible. Confirm coverage details directly with your insurer or provider before scheduling.

What should I expect during a sleep consultation?

A sleep consultation typically begins with a review of your symptoms, sleep habits, medical history, and any relevant risk factors such as body weight, cardiovascular conditions, or medication use. Your clinician may ask about snoring frequency, breathing pauses observed by a partner, daytime sleepiness, and how rested you feel after a typical night. Based on this review, the sleep physician will recommend next steps, which may include a home sleep apnea test, an in-lab polysomnography study, or further evaluation for a specific sleep disorder. Some practices offer a free initial consultation to help you and the clinician determine whether a full evaluation and in-person care make sense for your situation.

How does biomarker testing relate to sleep health and biological aging?

Biomarker testing measures specific substances in the blood that reflect how the body is functioning, including markers of inflammation, metabolic health, hormonal balance, and cardiovascular risk. Poor or disrupted sleep is associated with changes in markers such as high-sensitivity C-reactive protein, HbA1c, cortisol, and lipid-related markers such as ApoB. Over time, sleep disruption may contribute to accelerated biological aging, which differs from chronological age and reflects how your cells and tissues are functioning. Dumbo Health tracks these relationships through its SleepLongevityAge metric, built from a blood biomarker panel reviewed by board-certified physicians. The Core membership tests 51 sleep-longevity biomarkers twice a year for early members at $0.99 a day, billed annually. A physician can help interpret what biomarker results mean for your individual health.

What is a SleepLongevityAge score and how is it different from a sleep apnea diagnosis?

SleepLongevityAge is a proprietary metric developed by Dumbo Health that estimates how your sleep may be affecting your biological aging based on blood biomarker data and optional wearable device inputs. It is a wellness and screening tool, not a medical diagnosis. A sleep apnea diagnosis, by contrast, is a clinical determination made by a physician based on sleep study data including the apnea-hypopnea index, oxygen desaturation, and symptom history. Both tools serve different purposes. SleepLongevityAge helps you track how sleep may be influencing your long-term health trajectory, while a sleep apnea diagnosis confirms the presence of a specific sleep disorder that requires treatment. Abnormal biomarker results or a high SleepLongevityAge score should be reviewed with a healthcare professional. Learn more about the sleep longevity program at Dumbo Health.

How do I get started with sleep testing or a sleep longevity assessment?

Getting started depends on what you are looking for. If you have symptoms of sleep apnea and want to test from home, Dumbo Health offers a $149 at-home sleep apnea test with physician diagnosis typically within days of your test night. Available in Florida, Texas, Virginia, and Maryland. If you want to understand how your sleep may be affecting your biological age through biomarker testing, you can take the free sleep and longevity assessment at Dumbo Health to determine whether membership or testing makes sense for you. If you prefer in-person care with a sleep specialist in Philadelphia, many practices offer appointments within one to two weeks and some provide free initial consultations. A healthcare professional can help guide the right starting point based on your symptoms and goals.
