GeoVista Credit Union is celebrating 60 years! GeoVista Credit Union was founded as Fort Stewart Georgia Federal Credit Union in 1964 in Hinesville, GA. At GeoVista, you are never just another customer, you are a member who has a say in everything we do. That's because credit unions are different from banks. Members are literally the owners of the credit union. Becoming a member is incredibly easy. If you live, work, worship or attend school in Bryan, Bulloch, Chatham, Effingham or Liberty counties, we would love to be your credit union of choice.
