Get to know us
Variety of options
Our history in helping members obtain affordable health care costs goes back to 1971 when we were founded as the Greater Marshfield Community Health Plan, the first health maintenance organization (HMO) in Wisconsin, and the first rural HMO in the nation. The health plan became Security Health Plan in 1986.
In the intervening years we have grown significantly, and now serve more than 205,000 members throughout Wisconsin and beyond.
Security Health Plan is part of Marshfield Clinic Health System. For more information on Marshfield Clinic Health System click here.
