About Our Team
Our doctors are Board Certified, University-trained, Gastroenterologists that are experts in treating disorders of the digestive tract, colon, esophagus, intestine, liver, pancreas, and biliary system. Our accomplished doctors have been honored and distinguished in many ways, including being recognized as Boston Magazine’s Top Doctors, serving as clinical instructors at Harvard Medical School and being members of academic societies.
Our Nurse Practitioners have extensive training and experience specifically within gastroenterology. They are important advocates for our patients and are valued colleagues. Our team is competent, caring, patient, and dedicated to making sure your visit is the best possible.
Our practice was founded in 1983 by Doree T. Barton, MD, who died in the spring of 2015. He was a true pioneer in the clinical management of Crohn's disease and Ulcerative Colitis. Dr. Barton was uniquely dedicated to her patients and provided the highest quality care to thousands, and she leaves the legacy of an outstanding gastroenterology practice. For this, we are forever grateful.

- The services we have provided in the past will continue to be offered
- We will continue to operate from our current office
- Our contact information will remain the same
