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.

How to refer a patient

Simply fax a completed request form for outpatient consultation (available here), endoscopic procedures (available here), or motility tests (available here) to 984-974-3414. Upon receipt, all referrals are reviewed and triaged by a faculty gastroenterologist. When appropriate, patients may be re-routed to our general gastroenterology clinic or another of our GI specialty clinics (functional GI, IBD, or hepatology). We do not accept referrals directly from emergency departments.
