About
Members 1st Federal Credit Union is a member-owned full service financial institution located in Southcentral Pennsylvania. In 1950, we opened our doors with a desk and small counter outside the personnel office at the Naval Supply Depot in Mechanicsburg, Pennsylvania. We officially adopted the name of DAFCU (Defense Activities Federal Credit Union) in 1972 and opened our first branch office at the U.S. Army War College in Carlisle that same year.
