Our Corporate Social Responsibility Report: Momentum for All

We are proud to share our inaugural Corporate Social Responsibility (CSR) Report: Momentum for All.

Being a good corporate citizen has been a part of First Midwest’s DNA since the founding of our company. This report brings to life what we are all about—how we express our character, how we live our mission and values and how we hold ourselves to the highest standard in doing so.

Momentums in History: A Foundation Built on Relationships

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 our mission remains unchanged: helping our clients achieve financial success in the communities in which we live and work.
