California's Leading Sleep Medicine Practice
Advanced Sleep Medicine Services has been helping patients achieve better sleep for over 30 years. Our board-certified physicians combine clinical expertise with convenient home sleep testing to deliver care that fits your life.
30 Years of Better Sleep
Advanced Sleep Medicine Services (ASMS) was founded in 1994 with a single mission: make expert sleep medicine accessible to every patient who needs it. What started as a small practice in Southern California has grown into the state's leading sleep medicine organization, with over 20 locations and a team of board-certified physicians dedicated to diagnosing and treating sleep disorders.
We were early adopters of home sleep testing technology — recognizing that the most convenient, accurate, and affordable path to diagnosis was one that patients could complete from the comfort of their own beds. Today, thousands of Californians have received their sleep apnea diagnosis and started treatment without ever spending a night in a sleep lab.
We accept over 300 insurance plans, including Medicare and most major commercial insurers, because we believe that financial barriers should never stand between a patient and a good night's sleep.

"Having never sent out a testimonial during my 47 years of life, you folks must have obviously done something really right ... If you personally have never experienced Sleep Apnea you cannot possibly understand how amazing it was to actually sleep. Quite frankly, I forgot what sleeping was actually supposed to feel like. This may well have been one of the most positive experiences of my life. Thank You."
