Fergus Federal Credit Union is locally owned and operated. That means all decisions are made locally, by those who live and work in our community. Decisions can be made more quickly and on a more personal basis. It also means that we're better able to keep in touch with you and your needs.

Service was the original premise of credit unions and service remains the driving force behind credit unions today. Our only purpose is to serve our members, and we do it well.
