Shared Purpose. Mutual Values.

Frontier Mutual, an Illinois Farm Mutual, and Mt Carroll Mutual, an Illinois Domestic Mutual merged January 2017 to form Frontier - Mt Carroll Mutual Insurance Company. We are a progressive mutual insurance company whose primary business is devoted to protecting our policyholders in Illinois. We have been serving the people of Illinois since 1886.

Why Insure with Frontier – Mt Carroll Mutual?

For starters, there are no shareholders – so that means we put the needs of our policyholders first. And that results in better service… suggesting ways to minimize risk… settling claims more fairly and quickly. No wonder more than 135 million policyholders choose mutual insurance to protect their property. Become a part of something bigger. Become a policyholder of a mutual.
