Why Central One?
At Central One, you’re more than a member. You are part of a community that is built on trust, support, and shared success.
As a for-impact credit union, we’re here to make a real difference, providing personalized financial guidance to our members and giving back to our communities. Through hands-on volunteer work and local partnerships, we’re committed to building a stronger, more compassionate future for all.
Become a member
Becoming a member is easy, just open an account at Central One. If you live, work, worship, volunteer or attend school in Worcester County or parts of Middlesex and Norfolk counties, you qualify. Businesses and organizations within these counties are also eligible to become a member. Family or household members of existing members can also join.
Our history
Since 1952, we’ve proudly served Massachusetts residents. Originally founded for New England Electric System employees, we transitioned to a community-based credit union in 1998. This shift allowed us to offer better products and services, expand our membership, and increase community reinvestment. Today, we’re one of Central Massachusetts’ largest federal credit unions.
Every aspect of the services they provide is exceptional: knowledgeable, professional, friendly and courteous, and "go that extra mile" for members and their protection. Central One Federal Credit Union's model is unparalleled, in my opinion, barring none.
