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 eight hospital campuses in the New York metropolitan area, including Mount Sinai Hospital and the New York Eye and Ear Infirmary.
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 name was changed to The Icahn School of Medicine at Mount Sinai in 2012, after a $200 million grant from businessman Carl Icahn.
