Meet The Bank That Helps You Bank Boldly

At BOS, our goal is to develop life long relationships with our customers. We make banking easy, convenient, and personal.


A Proven History and Powerful Future

With a focus on community, Jack A. Marantz founded Bank of Springfield (BOS) in Springfield, Illinois in 1965. Today, the tradition continues under the leadership of Chairman of the Board, Tom Marantz; our President, Mike Pence; and Chief Executive Officer and Vice Chairman of the Board, Jason Knoedler.

From our roots as a neighborhood bank on the southeast side of Springfield, Illinois; BOS has grown to 15 full-service branches in Illinois and Missouri and one loan production office in Missouri. As we continue to expand operations, you have our promise to remain privately held and responsive to your needs.

Your Community is Our Community

BOS is committed to utilizing our resources to make a positive impact on the communities we serve. We are proud to sponsor many projects, organizations, and events. And if you’re in Springfield, be sure to check out the BOS Center in the heart of downtown.

Our employees continually dedicate their time volunteering for local organizations, including food, clothing and toy drives, blood drives, and numerous charity events. We are passionate about educating our communities through financial literacy programs and working with customers to grow their financial future.


Our Friend BOS Dog

In 1999, “BOS Dog” (pronounced Boss Dog), our brightly colored, child-friendly mascot joined the BOS team. Designed by our friend and Springfield, Illinois native Charlie Houska, he brings smiles to many bank and community events. BOS Dog enjoys visiting with kids and teaching them the importance of saving money for their future.
