About

Summary: - The page describes Out Patient Facility, a Hospitals and Health Care entity affiliated with Memorial Sloan Kettering (MSK) in New York. It appears to be a separate, small organization (3 employees) listed with MSK-friendly details, including contact numbers and two U.S. offices (Albertson, NY and NYC HQ). - It does not mention a Nassau or Herkimer location. The Nassau/Herkimer question is not supported by the listed locations (United States: two offices in New York: Albertson and New York, NY). If you’re seeking MSK locations near Nassau or Herkimer, this page does not provide those, and MSK’s official Nassau/Herkimer sites are not listed here. For accurate MSK locations, consider checking MSK’s main site for patient care locations in New York and surrounding areas.
