Referrals and Appointments

Most sleep studies are ordered by a physician who is versed in the study of sleep (for example, a sleep specialist, an ENT surgeon, pulmonologist or neurologist). If a patient does not have a sleep-qualified physician to order a test, the patient must be seen by our Sleep Center director, Stuart McCalley, MD. He will review the case to determine whether a sleep study is necessary.
