WELCOME TO THERESA MUTUAL INSURANCE COMPANY
"Neighbor helping Neighbor"
It's an idea as old as civilization itself and is the concept behind Theresa Mutual Insurance Company. We believe that the "neighbor helping neighbor" policy is what has kept the company in existence since 1879. We offer insurance coverages for farms, homes, mobile homes, rental dwellings, tenants, and small businesses. Auto insurance through 1st Auto & Casualty offers a discount for a supporting policy.
