In the aftermath of the Great Depression, C.D. Oberwortmann, Andrew Barber and Frank Turk made a personal commitment to bring quality banking back to the Joliet, Illinois area. In 1940, they founded Union National Bank and Trust Company of Joliet.

​

The bank’s original slogan was “The Friendly Bank,” which summarized the founders’ commitment to creating an institution that, first and foremost, served its community by making banking services conveniently available to customers. Since then, First Midwest has grown and evolved significantly, but their mission remains unchanged: helping clients achieve financial success in the communities in which they live and work.
