Vermont Gastroenterology is an independent and physician-owned medical practice providing state-of-the-art diagnostic services, consultations, and treatment for disorders of the digestive system at our Colchester, VT offices, with procedures performed at either Green Mountain Surgery Center or at the University of Vermont Medical Center.
Our caring physicians and support staff work directly with patients—often in collaboration with primary care physicians and other medical specialists—to address health issues relating to the esophagus, stomach, small and large intestine, and associated organs such as the liver, gall bladder, and pancreas.
Our practice is personalized and patient-centered. We believe that taking the time to answer your questions, understand your needs, and address your concerns is the best way to determine the most appropriate diagnostic and treatment options.
