How to schedule an appointment

All new patients must be referred by another physician. Your referring physician should simply fax a completed clinic referral form (available here), motility request form (available here), or procedure request form (available here) to 919-966-2508. Upon receipt, a UNC gastroenterologist will review the request and our scheduling office will call you to schedule the appointment. If you have any questions or need to reschedule your appointment please call 919-966-6000.

Research & Clinical Trials

Our center has a strong commitment to discovering new treatments for patients with esophageal diseases. It is not unusual for us to be involved in the development of new procedures and new medications months or years before they are available to the general public. Information regarding our current clinical research projects is available here. Please email us at with any research related questions.
