Kaiser Permanente, one of the nation's largest health care providers, broke ground Wednesday in Camp Springs, Md., for its second health care facility in southern Prince George's County.

The Camp Springs Medical Center will be a mile south of the Capital Beltway at 6104 Old Branch Ave.

"We wanted to provide easier access and a more convenient location while adding new members in the Prince George's County area," said Lou Ann Gower, director of analytical and capital planning for Kaiser Permanente.

The Camp Springs Medical Center will be Kaiser Permanente's 14th facility in the Washington-Baltimore area, and its second in Prince George's.

The one-story, 17,000-square-foot building will have 12 provider offices and a pharmacy. Medical services will include internal medicine, obstetrics and gynecology, orthopedics and general surgery.

Marshall Erdman and Associates Inc., a Virginia architectural firm, is designing and building the center.

Kaiser Permanente Health Care Program is the nation's oldest health maintenance plan, with five million members nationwide. The health plan provides care for more than 168,000 members in the Washington-Baltimore area.

The Camp Springs Medical Center is being built at a cost of $2.5 million. Completion is expected in the summer of 1988.
