DDSEP 10 Chapter Author Biographies

1. Esophageal Disorders


Biography, Benson T. Massey, MD, FACP

“Quality patient care requires careful listening to the patient’s own story of their problem,” said Benson T. Massey, MD, FACP, “so as to understand the concerns and goals for care from the patient’s perspective. For care to be effective, the patient must remain an active partner – within the entire health care team. The best quality care requires going the extra mile to obtain the best possible understanding of the patient’s condition. But one has to be honest and say “these things I don’t know” when the current limits of medical knowledge have been reached. My practice of medicine is dedicated to pushing back those limits.” Dr. Massey finished his Fellowship in Gastroenterology at the Medical College of Wisconsin Affiliated Hospitals in 1990, his Residency at the University of Rochester School of Medicine and Dentistry in 1986, and his Doctor of Medicine at Johns Hopkins University School of Medicine in 1983.
