Old Second National Bank



About Us

Unlike other Chicago-area banks, our heritage traces the advancement and evolution of the banking industry and the growth and expansion of the Chicago metropolitan area. The same local spirit that sparked that original group of early settlers to invest in and finance their town?s growth helped guide us as Old Second expanded throughout Kane, Kendall, DeKalb, DuPage, Cook, LaSalle and Will counties and the surrounding communities.

In addition to their commitment to community, our founders? fiscal discipline remains among our bank?s guiding principles. Backed by an unwavering sense of financial responsibility, we?ve persevered through the most challenging and rewarding economic climates and historical events of the late-19th century, the entire 20th century and the early 21st century.

Our balance sheet remains solid, our credit rating remains strong and our dedication to building strong and lasting relationships with our customers remains unparalleled. For over 140 years, Old Second consistently has helped businesses and individuals throughout the Chicago area START BANKING.


We proudly support the communities in which we operate, not only through our banking operations, but through our employees? volunteer and community-service efforts.

Giving back to the communities we serve has always been an important part of our culture as a local community bank. Whether it's a project-specific donation to help fund a new building for a homeless shelter or an ongoing financial partnership with a charity like Uni
