About Me

Michael S. Smith, MD, MBA is the Associate System Chief of Gastroenterology for the Mount Sinai Health System, and an Associate Professor of Medicine at the Icahn School of Medicine at Mount Sinai. He previously served as Chief of Gastroenterology and Hepatology at Mount Sinai Morningside and Mount Sinai West Hospitals, where he also was Director of the Esophageal Program.

Dr. Smith graduated magna cum laude from Princeton University with a concentration in molecular biology, after which he earned both an MD and MBA with honors in healthcare management at the University of Pennsylvania School of Medicine and the Wharton School of Business. He then completed a residency in internal medicine at the Hospital of the University of Pennsylvania, followed by a gastroenterology fellowship at the Columbia campus of the New York-Presbyterian Hospital.

As a member of the medical faculty at the Lewis Katz School of Medicine at Temple University and now at Mount Sinai, Dr. Smith’s clinical practice has focused on the diagnosis and management of esophageal disease, with a particular interest in Barrett's esophagus and esophageal cancer. His research has investigated how new tools, techniques and medications are best incorporated into everyday treatment of these conditions. Dr. Smith has given invited lectures throughout the US and around the world, and has served as a mentor to many physicians new to endoluminal treatments for Barrett's esophagus. He is a founding member, treasurer and executive committee member of the American Foregut Society, and will serve as the society's president in 2025-26.
