Who We Are

Our History


St. Mary's Hospital has been a beacon of health and hope for the city of Troy and surrounding neighborhoods for more than 155 years. The hospital is the heart of Seton Health, a comprehensive, integrated network of healthcare services providing care in Rensselaer, Saratoga and Albany counties. 

St. Mary's was founded when a local pastor requested the assistance of the Daughters of Charity in caring for fever-stricken immigrants in the 1840s. In 1893, Leonard Hospital opened in the northernmost portion of the city on property bequeathed by a local physician. These two Troy icons merged their strengths in 1995 to create Seton Health. Seton Health is a member of Ascension Health, the nation's largest not-for-profit Catholic healthcare system.

More than 1,700 Seton Health associates provide healthcare and support services at St. Mary's Hospital and more than 20 other sites. We are among the region's leading primary care providers, offering family practice and internal medicine, urgent care, OB/GYN and pediatrics. Seton Health's outpatient services include physical rehabilitation, medical imaging, incontinence and wound treatment, surgical services, cardiac rehabilitation, a nursing home, adult day care, and much more.
