Our History

Evergreen was founded in 1951 as the S.D. Warren Credit Union located in Westbrook, ME, where we served the employees and families associated with the S.D. Warren Paper Mill. Sappi later purchased the mill and continues to operate on the same site today.

As we grew and our membership expanded, we changed our name in 1999 to Evergreen Credit Union. To accommodate further growth, we built and moved into our new corporate offices at 225 Riverside Street on the western edge of Portland, one mile from our founding site at the mill.

To gain efficiencies and better serve all Cumberland County, Evergreen merged with Greater Portland Municipal Credit Union (GPM) in 2007. The GPM corporate office on Broadway in South Portland became our fourth branch, adding to Portland, Windham and Naples.

In 2018, we added York County to the communities we serve. In 2022, we began serving Oxford, Androscoggin, Sagadahoc, and Lincoln counties, making our total membership area 6 Maine counties. 

In 2024, we opened our fifth branch in Scarborough to better serve members in southern Maine.
