Elana Maser, MD

Upper East Side residents have a specialist close by. Elana Maser, MD offers gastroenterology care on the fifth floor of 17 E 102nd St, a mid-block building that blends into the neighborhood’s mix of pre-war walk-ups and medical offices. The practice focuses on conditions affecting the digestive tract—from routine screenings to managing chronic illnesses like Crohn’s disease and ulcerative colitis.

Gastroenterologists in dense urban areas often handle a steady stream of referrals; this part of Manhattan is no exception. Patients here typically arrive with concerns about acid reflux, irritable bowel syndrome, or colorectal cancer prevention. The office also performs diagnostic procedures such as colonoscopies and endoscopies, which are standard in the field but require precision and up-to-date equipment. Those needing an appointment can find the place just steps from Central Park, where the quiet side street contrasts with the usual bustle of Madison Avenue.

Directions to the office are straightforward—map here. For scheduling or questions, the number is (212) 241-8100. The practice operates within the broader network of Mount Sinai’s outpatient services, which may influence insurance coverage for some patients.
