A credit union is much more than a typical bank.
While a bank is owned by stockholders who are in the business to earn a healthy return on their investments, our credit union is a not-for-profit, cooperative financial institution owned by its members. Business decisions at St. Mary's are driven by what is in the best interests of the membership. As a credit union founded to help underserved individuals, we continue to believe that access to financial services for the underserved is an integral part of our mission. With membership open to anyone with the purchase of one share of capital stock for $5, we are committed to the credit union philosophy of "people helping people."
