Founded in 1941 as a source of loans and basic savings products, GCS Credit Union has always focused on the member. Through the years, that philosophy has served us well, helping us grow from a single office in Granite City to a full-service financial institution serving Illinois counties: Madison, St. Clair, Jersey, Macoupin, Montgomery, Bond, Clinton, Washington, Randolph, and Monroe. Anyone who lives, works, or attends school within these counties is eligible for GCS membership
