In 1963, a group of WKU faculty and staff decided to help other people at Western Kentucky University by loaning them money. The group determined a credit union was the best way to serve others. Western Kentucky State Credit Union was Incorporated and approved by the Department of Banking in January 1963. A few of the most innovative features of the Campbell Lane Branch include a living “Green Roof System” for added roof insulation, a Bioretention Basin which controls stormwater runoff, reclaimed wood timbers from a historic mill which eliminated the need for a sprinkler system, and the first commercially-installed Nanogel-insulated windows. Service One was the first financial institution to utilize cash-recycling machines in 2009 which streamlined service and eliminated the need for cash drawers for its member service personnel.
