Who We Are

Sleep Disorders Institute

The Sleep Disorders Institute (SDI) is a full-service sleep disorders center that specializes in the evaluation and treatment of disorders of sleep and wakefulness in adults and children. SDI’s main facility is accredited by the American Academy of Sleep Medicine, and our offices are affiliated with New York’s finest hospitals. Dedication to patient care and research are among the reasons why many doctors come to us for advanced training. Perhaps all of this is why we were named a “Center of Excellence” by New York Magazine’s issue on the Best Hospitals in New York.
