About Us

Thurston County Teachers Credit Union was founded in 1938 by a group of respected Olympia school teachers and community leaders seeking better loan and savings rates than were generally available during the tough post-Depression era.

In 1981 the credit union name was changed to Twin County Credit Union to reflect the growth and expansion of the credit union into Grays Harbor County. Since then, the credit union has expanded to more than 20 branches in western Washington and one branch in Oregon.

In 2006, Twin County Credit Union changed its name to TwinStar Credit Union to better reflect our growing and diversified member base. Then, in 2009, TwinStar expanded its field of membership to include all residents in the state of Washington and in 2011 expanded again to add the Portland, Oregon metropolitan area including anyone who lives or works in Multnomah, Washington, Clackamas or Marion counties.

With a long list of convenient electronic access options, surcharge free ATMs located nationwide and nearly 100 Shared Branches in Washington, people from all over the state can take advantage of the financial services offered at TwinStar.

TwinStar has developed some of the most innovative financial products available anywhere.  Kasasa Cash Checking offers a high dividend rate when certain account requirements are met and the ChoiceLine Home Equity Line of Credit account allows account holders to pay the loan at either fixed or variable interest rates, whichever fits the needs of the borrower.

Since 1938, TwinStar Credit Union has remained true to its roots, creating innovative and flexible financial products and services that are focused on helping members chart their course to financial success.

Today, TwinStar Credit Union counts more than 100,000 of your neighbors as members. TwinStar Credit Union is the 9th largest credit union in Washington with more than $850 million in assets.
