Korthase Flinn is one of Northern Michigan’s largest independent insurance and financial services firms. We began as a family-owned business in the 1930’s and while we have grown substantially, we continue to carry on the legacy of client trust and superior  personal service that our company was founded on. Today we operate three offices and service over ten thousand clients throughout the Midwest.
