We are owned by our membership, and as such, the profits we make are reinvested into providing better rates, convenient technologies and world-class service. Founded in 1952 as an occupational-based credit union for employees of the New England Electric System, Central One Federal Credit Union has grown into one of the largest federal credit unions in Central Massachusetts. We applied to change our charter to Community-based in November of 1998. The charter change paved the way for enhanced products and services, branch expansion, assisting more members in our communities and increased support of local non-profits.
