In 1956, Dr. Lee Gladstone built a clinic on Green Street in the city of McHenry.

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 Illinois Route 31 and Bull Valley Road and was named Northern Illinois Medical Center.
