Welcome to the Diedrich Agency!

We’re thrilled to announce that effective January 1st the Diedrich Agency will become part of Vizance Insurance.

Drew Diedrich explains “The industry has changed a great deal since my grandfather Carl started selling insurance. It’s a much more complex and competitive business now. From the very beginning our agency has prioritized and valued the relationships with our clients and the trust they place in us to meet their insurance needs. This new partnership with Vizance will bring significant resources to benefit our clients in an ever-changing insurance landscape.”

The Diedrich Agency will continue to operate in Ripon, Oshkosh, Berlin, and Fond du Lac. All Diedrich staff will continue to work in these offices serving our clients. Drew Diedrich and Tobin Storzer, owners of Diedrich Agency, will become shareholders in Vizance, a private family-owned company based in Hartland, Wisconsin. Management of the Diedrich offices will remain local, as will our commitment to the communities where we are located.
