Cooperative Center Federal Credit Union was chartered April 20, 1942 to serve the employees and members of the Consumers Cooperative of Berkeley, Inc ( Co-op Market Chain ). We continue to serve members from our original group, even though the Co-op Market Chain is no longer in business. These members see the Credit Union as their primary financial institution. This inherently stable "core" membership has provided a solid foundation from which to build.During the 1980s Cooperative Center became the survivor of a series of mergers with other credit unions in the area. Two of these were the Cal Berkley Credit Union and Alta Bates Credit Union. These, two along with our original Co-op Markets, continue to make up our largest field of membership.We have continued to expand our membership base by accepting qualified private companies, organizations and associations. To this day we continue to bring in other groups. This careful expansion has helped build a uniquely diversified membership around the stable core or original members.
