Healthcare. Re-Imagined.

HSHS St. Mary’s Hospital is entering a new era of healthcare in Decatur.  We are reimagining our footprint and care delivery model to ensure our mission continues as we serve our current patients and future generations in a modernized environment.

Founded in 1878 by three Hospital Sisters of St. Francis, HSHS St. Mary’s Hospital is an all-private room health care facility that combines modern technology with the caring spirit of the original founders. HSHS St. Mary’s is situated on a 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. HSHS St. Mary’s also offers a variety of community education and wellness programs. 

HSHS St. Mary's Hospital's approach to health care combines the compassion and human touch of more than a century of caring with the modern technologies available today.
