Section of Sleep Medicine Make an Appointment Ask a Question Refer Patient What do we do? We are committed to providing the highest quality integrated and innovative care, serving patients with a wide spectrum of sleep disorders. A multidisciplinary team of pulmonologists, psychologists, respiratory therapists and polysomnographic technologists team up to address clinical, educational, and research activities. Why National Jewish Health? Excellent patient care, positive treatment outcomes, and a robust educational mission establish the Sleep Center as a leader in the Rocky Mountain region. To better accommodate our patients, sleep studies are performed seven nights per week. The 14-bed sleep center is spread across two locations: central Denver on the main campus of National Jewish Health and the Denver Tech Center in Englewood. In addition to the National Jewish Health main campus, sleep clinic appointments can be scheduled at our Highlands Ranch office, the University Family Medicine Clinic in Westminster, or at the Anschutz Pavilion office on the University of Colorado Denver campus.
