About BOS
With a focus on community, Jack A. Marantz founded BOS in Springfield, Illinois in 1965. Today, the tradition continues under the leadership of Chairman of the Board and Chief Executive Officer, Tom Marantz.
From our roots as a neighborhood bank on Springfields southeast side, BOS has grown to a community bank with over $850 million in assets. Our first expansion outside Springfield was to Jacksonville, Illinois in 2000. We now have 12 locations throughout Illinois. You can find us in Springfield, Jacksonville, Chatham, Quincy, Swansea, Shiloh, Glen Carbon and Staunton. As we continue to expand operations, you have our promise to remain privately held and responsive to your needs.
