MADE IN MICHIGAN

Fueling Our Unique Regional Economy

As one of the few banks still headquartered in Michigan, we know our unique economy and business challenges well. We don’t make banking decisions with an algorithm created in a distant global headquarters. We get to know you, your business and your immediate needs to create opportunities for you, not obstacles.

Business Leaders Choose Clarkston State Bank



“Our last bank did not understand some of our accounting procedures. Clarkston saw right away why we approached it the way we did and were able to get us the funding we needed.”

“We had a personal banker from a big bank, and he was just a guy who wanted to take us to baseball games. As a business owner, I don’t have time to go to a baseball game. I want a bank that will respect my time and make sure things are handled, and handled correctly. Clarkston is truly our partner in business.”
