Dr. Joseph B. Felder, MD

Beyond midtown’s glass towers, Manhattan’s clinic scene is more scattered than you’d expect. Dr. Joseph B. Felder, MD doesn’t feel like another crowded lobby; the practice sits above Park Avenue’s quiet shoulder at 150 E 58th St, in the ANNEX building’s fourth floor. Gastroenterology as a specialty often ends up in back-office corridors, yet this office stakes a claim on an address that reads like a landmark instead of an afterthought.

Wide‐ranging digestive care starts with precision: colonoscopy and upper endoscopy anchor the roster, paired with capsule endoscopy for a non-invasive look inside. For ongoing issues, they handle acid reflux management and IBS evaluation with gentle diagnostics, while bile duct concerns are screened via ERCP. Liver health doesn’t get short shrift—fibroscan screening and hepatitis evaluation round out the offerings without a sales pitch. The senior clinician’s name above the door reads like a directory entry; the number underneath, (212) 472-8039, does the talking.

Planning the visit begins with one click: pull up the map. Once you exit the elevator, the sign pointing to Suite 4F is about as subtle as the neighborhood itself.
