Credit union expands in busy Spokane Valley corridor.

STCU will open its third Spokane Valley location on September 1 at Interstate 90’s Argonne exit.

The 3,157-square-foot Argonne Branch, 9209 E. Mission, is at the northeast corner of Mullan Road and Mission Avenue, adjacent to STCU’s existing Argonne Home Loan Center. It includes five drive-through lanes for teller and ATM access, a coin machine, Night Drop, and notary services.

Yost Gallagher Construction was the general contractor on the building that was designed by Bernardo/Wills Architects PC of Spokane. The credit union commissioned Spokane Valley artist Melissa Cole to create a colorful, 22-foot mural of the Spokane River on an interior wall (shown here).

STCU purchased the 2.5-acre Argonne site in 2012. Demand for a full-service branch site has steadily increased since the credit union opened the Argonne Home Loan Center on a small portion of the land in 2018. STCU membership has grown by nearly 50,000 since that time.

“Spokane Valley continues to grow, along with traffic at our Spokane Valley and South Valley branch locations,” said STCU President and CEO Ezra Eckhardt. “While use of online banking and our mobile app has sharply increased during the pandemic, our members of all ages continue to value in-person service from an STCU representative.”

Assistant Branch Manager Susan Leinan moved from STCU’s North Spokane Branch to lead the Argonne Branch team, which includes three member relationship officers and one teller.
