A merger with Lewis County Employees Credit Union in 1984 established another branch, with two more added in that decade.

Early in the millennial decade, the credit union further expanded with two additional branches while surpassing the $1 billion mark.

Branches are located in Bellevue, Chehalis, Everett, Lacey, Lakewood, Olympia, Seattle and Tumwater in western Washington; and Ellensburg, Medical Lake, Pullman, Spokane, Spokane Valley and Yakima in eastern Washington.

In 2017 the credit union partnered with Hands On Children's Museum of Olympia to launch the Learning for All Initiative, helping to expand museum programs and offer free access to underserved families in Thurston County.

Four percent of the annual net income is reserved for community give-back to local non-profits that fall within the credit union's three pillars of giving: Education, Self-sufficiency and Public Employees and Assets.
