Meet Our Sleep Specialists

Patients with sleep disorders may be referred to the Sanford Sleep Disorders Center in Bismarck by their family physician or specialist such as a pulmonologist, neurologist or ear, nose and throat doctor.

Comprehensive Care

Physicians from a variety of medical fields—neurology; pulmonary medicine; ear, nose and throat doctors—all work together to provide comprehensive diagnosis and treatment for patients suffering from sleep disorders.

Working in conjunction with an array of specialties including neurology, pediatrics, ENT, pulmonary medicine, psychiatry and psychology, we help patients identify the cause of their sleep problems and find ways to treat or effectively manage those conditions.
