Established in 1986 as an outgrowth of the Greater Marshfield Community Health Plan, Security Health Plan serves more than 187,000 people in a 32-county area in northern, western and central Wisconsin.

We offer a variety of health insurance options for employer groups, individuals of all ages, and families of various income levels. Our broad provider network includes doctors, other health care professionals, hospitals and pharmacies you know and trust. And because Security Health Plan is owned by Marshfield Clinic, and is run by physicians, we are committed to keeping members' best interests at heart. Decisions on what we cover are based on accepted, appropriate medical practice. It's a relationship you can trust.
