Located at the south side of 107th Avenue and Grand Avenue. Your health and safety is a priority, and to minimize the spread of COVID-19 we’re temporarily adjusting branch operations. Our Sun City walk-up ATM is open 24/7 daily. Since 1939, we’ve helped thousands of members save money and achieve their dreams. We’ve grown from a small credit union serving the educational community to the Valley’s largest credit union, dedicated to serving Arizona residents statewide. We encourage you to use our contactless banking options: online and mobile banking, phone banking, or ATMs whenever possible.
