Western Bridge Corporate Federal Credit Union, or WesCorp, was a financial services cooperative headquartered in San Dimas, California.

[2] In 1969, the leaders of California's credit union movement collectively recognized the need for a non-competitive service provider.

Natural person members, although allowed in the original charter, were discontinued as the corporate focused exclusively on institutional business.

On March 20, 2009, WesCorp was taken over by regulators and renamed Western Bridge Corporate Federal Credit Union.

[4] This effort failed to obtain sufficient funds and Catalyst Corporate Federal Credit Union was approved on December 14, 2011, to purchase its operations.
