Meet the Gastroenterology Team

Gastroenterology Specialists

The gastroenterology team at Lahey Hospital & Medical Center is made up of specialists who treat the full range of digestive and liver conditions. Our gastroenterologists, surgeons, endoscopists, oncologists, radiologists, pathologists and nurse practitioners work together to bring to each patient the latest treatments and personalized care.

Lahey’s large group of specialists includes more female gastroenterologists than any other center in the U.S. That means women who prefer a female provider will get an appointment more quickly.
