Our Mission

To create an environment where compassionate medical trainees can learn to provide exceptional quality care to the patients we serve.


In July 2015, the MedStar Georgetown University Hospital fellowship integrated with MedStar Washington Hospital Center enlarging the program to three participating hospitals including MedStar Georgetown University Hospital (MGUH), MedStar Washington Hospital Center (MWHC), and the Washington, D.C. Department of Veterans Affairs Medical Center (VAMC). This integration increased the number of fellows to 18. 

The MedStar Georgetown University Hospital Gastroenterology Fellowship Program is an ACGME- accredited program offering an outstanding, comprehensive three-year training program in gastroenterology and hepatology. Our program is designed to provide a scholarly training environment for fellows to develop into academic subspecialy consultants, clinical investigators, and clinical gastroenterologists. In addition to providing outstanding clinical training, we strive to provide the scientific foundation necessary to foster the development of our trainees into independent clinical investigators. To attain these goals the program is structured for trainees to achieve appropriate medical knowledge and procedural skills in the field of digestive diseases, as well as to develop the interpersonal and communication skills and professional attitudes necessary to function as highly competent subspecialists in this field.

Expanding the Gastroenterology fellowship to three hospitals significantly broadened the clinical experience and research opportunities for all fellows in the combined program. Fellows rotate through all three hospials and participate in the care of patients with a wide range of clinical problems in all stages of illness. Clinical fellows receive 36 months of clinical training. Fellows receive research training and participate in scholarly activity.

Entering fellows must have completed an ACGME accredited three-year residency program in Internal Medicine in the United States or Canada.
