Our History

Treimer's Insurance Agency, Inc. is an Independent Insurance Agency that was established in 1915 by William Treimer.  Over the years, the Agency expanded to include his son's, Virgil Treimer and Donald Treimer.  Later, Duane Kolpin joined Treimer's as a partner with grandson's, David Treimer and William Treimer joining the family business as owners. In 2025 the business was purchased by William's son, Marcus Treimer, and Matt Mills. Now we continue the tradition of a full-service family business.  We are fortunate to have many long-term friendly and knowledgeable employees.  The companies we write for are chosen very carefully, resulting in an outstanding selection of strong companies that allow us to provide a wide selection of competitively priced coverage for almost any insurance need.  We appreciate the opportunity to work for you.
