Gastroenterology Fellowship

We offer a three year fellowship training program in Gastroenterology. Fellows are trained in endoscopy in both outpatient and inpatient settings and in the diagnosis and clinical management of GI disorders. Fellows have dedicated research and elective months to excel in scholarship and to develop skills in particular areas of interest.

The fellows are involved in multiple conferences to include GI core curriculum, case conferences, pathology, research, journal club and morbidity and mortality conference. We are a collegial group that thoroughly appreciates the positive contribution that our fellowship program makes to our division as a whole. We participate in the National Resident Matching Program (NRMP). Applications must be submitted through the Electronic Residency Application Service (ERAS).

We appreciate your interest in our fellowship program. For more information, contact our fellowship coordinator, Tierney Godfrey, at
