History

In 1953, several members of the Leominster community met to discuss a growing concern.  People needed to borrow money locally and there was no local resource to do so. These community members responded to the need for a local institution that could provide small loans at reasonable interest rates.  That response was All One Credit Union.

All One Credit Union was founded in 1954. Initially, the credit union was open one night weekly.  Its office was the back room of a local printing press. During the 1960s, assets increased to $105,000 and membership expanded to more than 400 members.  In the 1970s, the credit union membership exceeded 4,500.  It became obvious that a new, full-service building was needed to serve member needs.  A corporate office and main branch were constructed in 1972. AOCU continues operations at this site today.

In 2010, AOCU opened the doors to its new 30,000 square foot Executive and Operation Building adjacent to the main branch and corporate offices.

Today, All One Credit Union serves the financial needs of North Central Massachusetts communities. AOCU is proud to claim nearly 40,000 members and assets of more than $900 million. All One Credit Union provides lending, deposit, and business services in Worcester County through a network of branches, ATMs, telephone, mobile and online banking services.  Branches are located in Leominster, Worcester, Clinton, Holden, Sterling, and North Leominster. AOCU operates four high school branches at Clinton High School, Fitchburg High School, Wachusett Regional High School, and Worcester Technical High School.
