About GCS Credit Union in O’Fallon

GCS Credit Union has been in Illinois providing loans, basic savings, and other banking services since 1941! We started as a single location, but have grown to support Sangamon, Logan, Macon, Marion, Jefferson, Perry, Jackson, Williamson, Jersey, Macoupin, Montgomery, Madison, Bond, Clinton, St. Clair, Monroe, Washington and Randolph counties.

There are many benefits to joining a credit union. We are a not-for-profit, member-owned financial cooperative. We focus on our members’ financial needs, and aren’t interested in making a profit off of them. Meet with one of our GCS Credit Union employees to learn more about how joining a credit union can benefit you and your community.
