Welcome to Greater Washington Sleep Doctors!

Marc Raphaelson, MD is one of the country’s premier specialists in sleep disorders and neurology.  He is a consultant at the National Institutes of Health, a Fellow of the American Academy of Neurology and of the American Academy of Sleep Medicine, and a frequent faculty member at national meetings.  His training, publications,and honors are listed in a separate page of our site. 

Home sleep testing is our main diagnostic test.  People who snore and who are likely to have sleep apnea, usually may be tested at home and treated with smart technology.  Most do not need testing in the laboratory.  Full overnight and daytime testing is available to diagnose other disorders of sleep and wakefulness.   

We help people who have trouble sleeping, trouble staying awake, or other problems with their sleep. We are experts in treating people with snoring, sleep apnea, insomnia, restless legs syndrome, shift work sleep disorders, and similar medical problems.

Our mission is to provide you with the best possible healthcare experience with each visit.  We ask you to write down your concerns, medical history, and general information for every visit! It’s surprising how often this helps avoid medication conflicts or other problems.

Our office locations for patient visits are in Leesburg and Fairfax/Annandale, Virginia, and in Bethesda, MD. For locations and directions to any office, click under the office location above.
