One Mission


In 1884, Memorial Sloan Kettering — then known as the New York Cancer Hospital — was founded in Manhattan. It was the first hospital in the United States dedicated solely to cancer care at a time when few treatment options existed. Fast-forward 135 years through countless extraordinary advances in research, treatment, and education, and MSK has grown to be the world’s largest private cancer center, setting the pace for a field that continues to evolve at incredible speed.

A network of more than 20 patient care facilities around New York and New Jersey has flourished from that original hospital on the Upper West Side.

In 2019, the institution’s capacity expanded further still: MSK Nassau opened its doors to residents of Long Island and eastern Queens.

The year also marked the culmination of a vision many years in the making — the completion of the David H. Koch Center for Cancer Care at Memorial Sloan Kettering Cancer Center on New York City’s Upper East Side.

Take a look inside and see how one mission serves as the foundation for these world-class facilities, guiding each person who walks through the doors.
