Digestive Health

Gastroenterology Services


With our partners on the mainland, Nantucket Cottage Hospital is able to provide access to some of the region’s finest gastroenterologists to care for your digestive health needs without ever having to leave the island. Douglas Horst, MD, and James Rabb, MD, are both affiliated with Beth Israel Deaconess Medical Center, board-certified in gastroenterology, and travel to Nantucket Cottage Hospital several times every month to see island patients. We perform colonoscopies and endoscopies right here on Nantucket, and our team performs diagnostic tests and treatments to manage diseases of the entire digestive system. A physician referral is required to schedule an appointment with one of our visiting gastroenterologists. Please have your primary care provider send a referral to the specialty clinic coordinator.
