Our medical staff includes sleep physicians of various medical backgrounds. For the past 30 years, physicians who specialized in sleep problems were initially trained in a related field – pulmonary medicine, neurology, otolaryngology, and psychiatry among others – and specialized in sleep after their initial training. Our experienced medical staff comes from many of these fields.
