About Us

Founded in 1949 by the City of Billings Fire Fighters, Rimrock Credit Union initially operated out of the trunk of a car. By December 31, 1949, Rimrock Credit Union served 16 members and had $63.11 in assets. Membership grew to include the City of Billings Police Department and eventually all employees of the City of Billings and Yellowstone County. Additional membership expansion allowed for persons with registrations issued by the City of Billings or Yellowstone County, employees of adjoining counties to Yellowstone County, and all taxpayers paying $50 or more in property taxes in those adjoining counties. With mergers of MDU employees, SuperValu employees, and union construction employees, Rimrock Credit Union has grown to hold assets of over $37 million and serve more than 3,500 members.

Since its inception, Rimrock Credit Union’s focus has been to provide exceptional service to all members by emphasizing the importance of the cooperative spirit. The philosophy of “people helping people” continues to be a priority today, just as it was back in 1949.
