About Us

Ocean Sleep Medicine was founded in July 2016 by Dr. Gary Feldman, a longtime fixture in Southern California sleep and behavioral medicine. After 10 years as the Director of the Stramski Children's Developmental Center at Miller Children's & Women's Hospital Long Beach, Dr. Feldman saw a need for a solution-based approach to sleep medicine and other behavioral and developmental challenges.

At Ocean Sleep Medicine, we aim to provide comprehensive, big-picture solutions for children and adults with sleep & behavioral conditions. Unlike many services that provide partial or fragmented care, we cover consultations, assessment, diagnosis, and treatment. Our staff are highly specialized in dealing with a wide variety of behavioral conditions including autism, ADHD, down syndrome, and other special needs conditions, as well as the sleep challenges that may result from these conditions.
