About Us
Your Local Medicare Partner in Michigan
Korthase Insurance was built on a simple belief: every Michigan senior deserves clear, honest guidance when it comes to Medicare — without the pressure, confusion, or sales tactics.
Our Story
Bill Korthase has spent years helping Michigan seniors navigate one of the most important decisions of their lives — choosing the right Medicare coverage. What started as a passion for helping people in his own community has grown into a trusted local agency serving seniors across Michigan.
Unlike large call centers or national brokers, Korthase Insurance is personal. When you call, you talk to Bill. When you have a question in March, you can still reach Bill. That kind of ongoing, relationship-based service is rare in the insurance world — and it's exactly what sets us apart.
Bill represents over 20 insurance carriers, which means he has no incentive to push one plan over another. His only goal is finding the coverage that's right for you — based on your doctors, your medications, and your budget.
