About Unity


First envisioned by community leaders to meet the health care needs of the growing suburban population, Park Ridge Hospital opened its doors in 1975. In 1997, Park Ridge aligned with the former St. Mary's Hospital located in the city of Rochester to form Unity Health System. In 2006, the name of the hospital was changed to Unity Hospital.

At Unity Health System you'll find the friendliest and most compassionate people dedicated to providing the best possible health care experience. We have over 70 locations in Rochester and Monroe County, including Unity Hospital, located on the Unity Park Ridge Health Care Campus in the town of Greece and the Unity St. Mary's Campus in Rochester. Key programs include Aging and Community Services, Behavioral Health, Neurosciences, Orthopaedics, and Women's Services. The Village at Unity is Unity's senior living community that offers a full continuum of housing programs including independent, enriched living, and a memory care community. ACM Medical Laboratory is a world leader of patient and clinical trials testing, with locations in western New York, York, England, and India, and lab partnerships across the globe. Our shared commitment to delivering health care the way it should be is reflected in our overall employee and patient satisfaction ratings and quality outcomes.

Unity Hospital is accredited by The Joint Commission, and is affiliated with the University of Rochester School of Medicine and Dentistry.
