BOS Celebrates 60 Years

Jack Marantz

BOS is celebrating the bank’s 60^th anniversary on October 29^th, 2025. The bank was founded in 1965 by Jack A. Marantz and a group of local business people in Springfield, Illinois. The original branch is still in operations at 2600 Adlai Stevenson Drive. Jack’s vision when opening the first branch was to provide the community with exceptional banking products and services through excellence and local ownership.

The tradition continues under the leadership of Tom Marantz, Chairman of the Board, Jason Knoedler, Chief Executive Officer, and Mike Pence, President.

“I am most grateful for what we have been able to do for our communities alongside a group of people that mean so much to me,” says Tom Marantz. “60 years is a lot of history but feels quick at the same time.”

In 2000, the bank first expanded into Jacksonville. Today, BOS serves 13 communities and 16 full-service branches in Illinois and Missouri. The most recent expansion markets include Kansas City, Bloomington – Normal, and Champaign.

60 years later, the bank’s employees have grown from a team of 4 to over 300 strong, and the vision remains the same. "We built BOS one customer at a time and will continue to prioritize lifelong relationships with our customers, employees, and the communities we serve”.
