Tools for Building a More Successful Business


Opportunities. Not Obstacles.
Where others start with “no,” we find ways to make business possible.
Great business banking begins with listening to you. This allows us to provide tailored cash management, commercial loans, merchant processing solutions and more to help you grow.

Local. Regional. National.
Based in Southeast Michigan. Local know-how, world-class capabilities.
Our decision-making doesn’t happen in some distant metropolis. Right here in our community, we combine top-tier banking experience with local common sense you can trust.

You Are More Than a Balance Sheet
We’re proud to back the people and vision behind the numbers.
Direct, honest service is at the core of our daily work. Tell us about your unique vision, how your business ticks, and we’ll find a solution that is designed for you – not a template.

Executive Banking Services
Exceptional banking services that save time and money for busy business owners.
We’ve designed business checking and savings accounts, merchant services, treasury management services and more to ensure your cashflow is smooth and efficient.

Made for Michigan Businesses
We understand the unique business banking needs of our local industries and economy.
The economic landscape in Southeast Michigan is unique – we get that. The big banks don’t. From a working capital line of credit to a commercial real estate mortgage, we tailor to fit you.

The Company We Keep
“They create opportunities, not obstacles. That’s why we bank here.“
Because you work directly with our local lenders and bankers, we have answers on the spot and make decisions quickly. No bureaucracy, no red tape. We’ll help you find a path forward.

The intersection of big ideas and getting it done.

We help companies throughout Southeast Michigan launch new ideas, scale their operations, reach new customers and grow their business.



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.”
