DeGraff Memorial Hospital, first established in 1914, joined Kaleida Health in 1998. DeGraff provides medical, surgical, medical rehabilitation and subacute services, and critical care, as well as a full range of ambulatory services. It scores at or above national standards for quality indicators and patient satisfaction, and its emergency room services are available 24/7. It is also the largest private employer in North Tonawanda. Though part of the region's largest health system, DeGraff retains its community hospital character and is enthusiastically supported by numerous volunteers and the community-at-large.
