Credit Union History

Where the entire community benefits

Since its founding in 1939 by a handful of Bell Telephone Company of Pennsylvania employees, TruMark Financial Credit Union has grown to be a leader in the credit union industry. TruMark Financial provides savings, transaction, and credit services solely for its members. In 2005, the credit union's field of membership changed to include anyone who lives, works, worships, volunteers, or attends school in the Southeastern Pennsylvania counties of Bucks, Chester, Delaware, Montgomery, and Philadelphia.
