About

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. As Old Second expands throughout Chicagoland and the surrounding communities, our commitment to a better banking experience remains steadily on course. Backed by an unwavering sense of financial responsibility and focus on humanity, we've persevered through the most challenging and rewarding economic climates and historical events since the late nineteenth century.

For more than 150 years, Old Second has consistently put businesses and individuals throughout the Chicago area first, and we're only getting started.
