Gastroenterology & Hepatology Team

"Our section is divided into four specialty service areas or Centers of Excellence to provide you with the services you need, when you need them. Each center has a team of gastroenterologists working together with surgeons, nurse practioners, research coordinators, and other medical specialists as appropriate.

Our physicians and nurse practitioners are members of the faculty of the Dartmouth Medical School, and are recognized for their clinical, teaching, and research skills."
