Our history? It’s not nearly as exciting as your future.

Our story started over 110 years ago. Since then, we’ve grown quite a bit, but we’ve never outgrown the idea that friendly, personal service truly matters.

Today we operate 88 branches in Indiana, Illinois, Ohio, and Kentucky. In every one, we do our best to build on our heritage of being a force for good. We encourage our employees to get involved in their communities whether through volunteering, financial education, or charity work. We welcome you to stop by one of our branches, but if you can't, catch a more personal glimpse of who we are and what we are about by checking out our Facebook page or Twitter feed.

Every day, you’ll find us working to strengthen the communities we serve. We’re passionate about helping our customers live better lives.

We’re a complete provider of both consumer and commercial financial services. We pride ourselves on providing a unique mix of small-bank service and big-bank services. Despite our regional presence across the Midwest, we believe in local decision-making.

In addition to providing traditional banking services, MainSource Bank offers insurance, brokerage, and trust services in all of our locations, allowing us to be your single source for the full range of financial services.
