NuMark Credit Union History

NuMark Credit Union has grown by following the “people helping people philosophy” and has been serving our community for over 60 years. In 1996, two credit unions merged to form NuMark Credit Union. Members Equity Credit Union resided at our Joliet Office. Dynamic Credit Union was located at our office in Countryside.

Members Equity Credit Union was originally called Earthmovers Credit Union of Joliet and established in 1954. The name was changed in 1983 to Members Equity. The credit union was originally formed to serve the employees of Caterpillar Tractor Company (CAT).

Dynamic Credit Union started out as Diesel Credit Union. The name was changed to Dynamic Credit Union in 1987. The union employees of the Electro-Motive Division of General Motors Corporation (EMD) organized the credit union in 1942.

NuMark Credit Union currently represents over 260 Select Employee Groups (SEGs) and provides services to those who live or work in our membership area map. See our long history of mergers.
