California State Employees No. 20 Credit Union was formed in January of 1951. The credit union was formed by a group of professors and employees of Humboldt State College. They formed the credit union with a desire to assist each other with reasonably priced loans and a good return on their savings. In 2017, the credit union was granted a field of membership expansion to serve those who live, work, or worship in Humboldt, Del Norte, and Trinity counties. In 2018, the credit union changed its name to Compass Community Credit Union to better reflect this new field of membership.
