A ribbon-cutting ceremony was held on board the Marine Corps Air-Ground Combat Center Friday for a new medical clinic. The Adult Medical Care Clinic will deliver health care to active-duty service members at the Combat Center. The 45,000-square foot clinic cost $21 million to build and replaces a building that dates back to 1952. The clinic is under the command of Navy Captain John Lamberton, the commanding officer of the Robert E. Bush Naval Hospital at the base.
