Icahn School of Medicine at Mount Sinai

The Icahn School of Medicine at Mount Sinai (ISMMS or Mount Sinai), formerly the Mount Sinai School of Medicine, is a private medical school in New York City, New York, United States. The school is the academic teaching arm of the Mount Sinai Health System, which manages seven hospital campuses in the New York metropolitan area, including Mount Sinai Hospital and the New York Eye and Ear Infirmary. As of 2025, Eric J. Nestler is the dean of the Icahn School of Medicine, and Dr. Brendan Carr serves as the President and & CEO.

The School is a teaching hospital first conceived in 1958. Due to simultaneous expansion initiatives at the hospital, classes did not begin until 1968. Its initial name, Mount Sinai School of Medicine, was changed to The Icahn School of Medicine at Mount Sinai in 2012, after a $200 million grant from businessman Carl Icahn.

Academic programs include MD, PhD and dual degrees, and the Graduate School of Biomedical Sciences offers 13 degree-granting programs, conducts basic and translational research, and trains postdoctoral research fellows. Its campus is located on Manhattan's Upper East Side, between Fifth and Madison Avenues, stretching from East 98th Street to East 102nd Street.
