California's leading sleep medicine practice

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 100+ 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.
