Our History

Following World War II our native sons returned home to begin retooling the country’s factories and economy. In Martinez, many of our American heroes resumed their “state side” lives by going to work for Shell Oil Refinery.

A few years later, in the summer of 1947, a group of employees formed a credit union for Shell refinery workers and their families. The SWS Federal Credit Union has been part of the local community ever since.

Today, the ranks of the SWS Federal Credit Union have grown to nearly 4,000 and membership is open to all people who live, work, worship or attend school in the Contra Costa County. Over the years the spirit of the brave men and women who came back from war so many years ago to care for their family’s wellbeing and financial health lives on.

The families of many of the original members are still involved in their credit union today—the old credit union mantra of people helping people is still valid—and your local credit union is still working to help support financial health in the community.
