The MetroHealth System is a nationally ranked non-profit, public health care system located in Cleveland, Ohio. Founded in 1837 as City Hospital, The MetroHealth System serves the residents of the city of Cleveland and Cuyahoga County. It is one of the three major health care systems in Cleveland, Ohio, along with Cleveland Clinic and University Hospitals of Cleveland. In 1972, MetroHealth (then referred to as Cleveland Metro General Hospital) built a new medical center at its Scranton Road location. The current building is two cylindrical towers connected with a central core, which was renovated in 1995. In 1982, MetroHealth established its Metro Life Flight air ambulance service. Metro Life Flight has completed more than 90,000 medical missions, all safely. This air ambulance service is internationally known and has trained crews from Poland to Japan. They use the EC-145 for their air ambulance service and a modified Lear Jet is used for transferring patients further distances.
