Our History

NuMark Credit

NuMark’s mission is to enrich the financial lives of our members. With our recent merger with Pioneer State Bank, we now have over 170 employees, thirteen Chicagoland branches, and over 50,000 combined members. NuMark Credit Union offers a full menu of financial services from mortgage and auto loans to free checking accounts and business services. We remain dedicated to putting our members first, treating them like family and helping them do more with their money. We help members get to their fantastic future faster.

NorthStar’s History

Founded on the principle of people helping people, NuMark Credit Union began as a small community effort to offer financial support and guidance to our members. Since then, we’ve expanded our services and embraced new technologies that, today, allow us to deliver unparalleled financial services to the communities we serve.


1942 - Our Origin

In 1942, the union employees of Electro-Motive Division of General Motors Corporation (EMD) in Countryside organized to form Diesel Credit Union. They changed their name to Dynamic Credit Union in 1987.
