About

Founded in 1878 by three Hospital Sisters of St. Francis, HSHS St. Mary’s Hospital is a 244-bed, all private room health care facility that combines modern technology with the caring spirit of the original founders. St. Mary’s is situated on an attractive 21-acre campus overlooking Lake Decatur and offers a broad spectrum of comprehensive health services, including the latest diagnostic equipment, interventional cardiology, surgical and medical intervention, emergency medical care, outpatient radiation therapy, pain management and a sleep center. St. Mary’s also offers a wide range of community education and wellness programs. The hospital also has both a unique intergenerational day services program and the community’s only provider of hospital-based behavioral health services for all ages.
