Known for its cardiovascular, orthopedics, cancer and wellness programs, Centegra Health System continues to grow and develop services to meet the needs of the community. This desire to serve the region comes from the organization’s deep roots in the Northwest suburbs.


In the early days of the 20th century, there were several small practice hospitals in Woodstock. In 1914, a group of physicians obtained a charter for a hospital in the home and office of Dr. Hyde West. The success of this hospital was such that a second hospital was built on South Street in the city. This hospital, which was named Woodstock Memorial Hospital, is now home to administrative offices and outpatient Behavioral Health Services.


In 1956, Dr. Lee Gladstone built a clinic on Green Street in the city of McHenry. The first and second floor included an emergency room, operating room, reception areas and offices for outpatient physician care. The ground floor provided 22 beds for new born, pediatric and adult patients. A McHenry Hospital addition was soon built near the clinic on Waukegan Avenue. With the rapid growth of population, a new McHenry Hospital was built in 1984 on Route 31 and Bull Valley Road and was named Northern Illinois Medical Center.

Centegra Health System is formed

In the early 1990s, health planners in McHenry County recognized the need to coordinate medical services for the growing health needs of the area. Centegra Health System was created to provide patients access to high-quality care and advanced technology.In 1995, a new Woodstock Hospital was built on Route 14 and Doty Road. It was named Memorial Medical Center, then Centegra Hospital-Woodstock.

Centegra Health System expands to Huntley

As a response to population growth, in 2006 Centegra Health System purchased land at the intersection of Algonquin and Haligus roads in Huntley, Ill. In 2008 a medical office building opened to provide Centegra Immediate Care and Centegra Physician Care services to the community. The facility now also houses Centegra Back & Spine Center. The same year, Centegra Health Bridge Fitness Center opened to provide community members access to fitness and wellness services.

Centegra Hospital-Huntley

The populations of southern McHenry County and northern Kane County continued to grow, and in 2010 Centegra Health System filed an application for a certificate of need with the Illinois Health Facilities and Services Review Board to build a new hospital in Huntley. The health system broke ground in 2014 and the hospital welcomed its first patients on Aug. 9, 2016. The 128-bed facility provides access to a Level 2 Trauma Center, surgical services including a cardiac catheterization laboratory, a 20-bed Family Birth Center, Medical-Surgical services, an eight-bed Intensive Care Unit and a Centegra Hip & Knee Replacement Center. Children have 24/7 access to a higher level of inpatient care thanks to Centegra’s partnership with Ann & Robert H. Lurie Children’s Hospital of Chicago, which brings pediatric inpatient hospitalists to Huntley to care for children who are inpatients or who need consultations in the Emergency Department.
