West Side Mutual Insurance Association was founded in 1874 by local individuals seeking to provide affordable insurance protection for themselves and others like them in Linn County, Iowa. You simply can’t get more local than this. Most of the money spent stays within Iowa. When you purchase local, you get better service and create more jobs all while investing in your community. Effective 1/1/2024, Lincoln Mutual merged with West Side Mutual. If you have any questions regarding your current policy please reach out to your agent.
