Hospital History

Since 1973, St. Mary Medical Center has met the healthcare needs of the Northwest Indiana community, having started through the ministry of the Poor Handmaids of Jesus Christ. This order of Ancilla Domini sisters began their ministry in Lake County when they came to Mercy Hospital in Gary in 1913. The sisters continue their mission here today, at St. Mary Medical Center and throughout Lake County.

In 2001, St. Mary Medical Center became part of Community Healthcare System, comprised of St. Mary Medical Center in Hobart, St. Catherine Hospital in East Chicago, and Community Hospital in Munster. St. Mary Medical Center remains dedicated to its Roman Catholic tradition. It is our goal to be the premier hospital system in Indiana. Our dedication to this end is evident in the caring spirit of our staff, coupled with the best facilities and technologies we can offer our patients and their families.

In 2004, the hospital expanded with a new $40 million Patient Tower offering comfortable, private rooms and advanced bedside technology. During the next decade, growth continued with the opening of a new advanced imaging center, a new and expanded emergency department, the opening of additional outpatient locations in Portage, Hobart and Valparaiso.

In 2015, St. Mary Medical Center ushered in a new era of surgical care with the opening of a $40 million four-story Surgical Pavilion and ICU, adding new surgical suites and intensive care unit, along with a new central sterilization department, post-anesthesia care unit, phase II recovery unit and same-day surgery. The same year also saw the acquisition of the TrueBeam system – an innovative cancer treatment technology – and the opening of the newly expanded Portage Health Centers I & II.

The top two floors of the Surgical Pavilion are in the process of being finished to meet growing healthcare needs, as part of our commitment to providing the highest quality care with the most advanced technologies, to provide patients of Northwest Indiana the finest health care available today.
