This led to a move to the Hospital of St. Raphael in 1974 to become Chief of Gastroenterology where his love of patient care and teaching could be pursued. Here, he became instrumental in setting the standards of practice for the New Haven area for a generation of future gastroenterologists in training, while maintaining a busy practice.
