Program Director's Message
The three-year gastroenterology fellowship provides extensive experience in all aspects of gastroenterology, endoscopy, hepatology and nutrition. Our fellows have the opportunity to become expert in these areas through Winthrop's formalized centers of excellence with state-of-the-art equipment and through rotations in advanced hepatology and liver transplantation at New York University. Graduating fellows successfully establish themselves in academic or clinical careers of their choice. Our fellows have presented abstracts and posters at the annual meetings of the American Gastroenterological Association, American College of Gastroenterology, and at Winthrop University’s Research Day.
