Wellstar Kennestone Regional Medical Center is a major tertiary-care hospital located in Marietta, Georgia, serving most of northern and central Cobb County, Georgia, as well as adjacent counties. Kennestone Hospital opened in June 1950 as a 105-bed-facility. It was named after the land which it was built upon, where both Kennesaw Mountain and Stone Mountain were visible. In 1959, the hospital's capacity increased to 300 beds with the opening of the south wing.
