Your Local Cooperative Banking & Financial Institution Since 1954!
Although we changed our name to All One Credit Union in 2024, our history started long before that.
We opened our doors in 1954 as Leominster Credit Union, a member-owned, not-for profit cooperative financial institution. For over 70 years, we have provided North Central Massachusetts residents with a full range of deposit, lending, and other financial services. Today, we are proud to claim more than 40,000 members.
All One Credit Union is headquartered in Leominster, MA. Financial services are provided through a network of branches and ATMs, as well as telephone, online, and mobile banking channels. Our seven branches are located in Leominster, Worcester, Clinton, Holden, Sterling, and North Leominster.
At All One, we are committed to providing quality products and services to our members. We use the latest technology and innovation for members’ ease and convenience. We strive to deliver these services professionally, courteously, and promptly.
Another example of our commitment to our community is the development of our Financial Education program, offered through both our community and school branches. The program is currently available at Clinton High School, Fitchburg High School and Wachusett Regional High School, and as of September 2025, Worcester Technical High School was added – bringing the total to four schools.
As we enter this next chapter of our story, we are more dedicated than ever to serving our members and embracing the communities we call home. Our new name embodies our values, encompasses everything we stand for, and is inclusive to all.
Welcome to All One Credit Union; we’re happy you’re here.
