Credit unions are cooperative financial institutions that are owned and directed by our members. Credit Unions are operated for the purpose of promoting thrift, providing credit at reasonable rates, and offering other financial services and assistance to the members. Credit unions are unique financial institutions that live up to the expression “not  for profit, but for people.” Credit unions are comprised of member-owners whose assets are pooled to provide loans and financial services to one another.

Credit unions differ from banks in a number of ways. Credit unions are not-for-profit cooperatives and owned by their members; other financial institutions are owned and controlled by outside stockholders. In addition, credit unions are operated by mostly volunteer boards, whereas other financial institutions are controlled by compensated boards.

The very first credit union was established in Europe in 1844. In 1908, the first credit union in the United States was founded. By 1934, Congress had passed the Federal Credit Union Act. The credit union movement has been growing strong ever since.
