Sentinel Federal Credit Union

Sentinel Federal Credit Union has been guarding and protecting the financial well-being of our members since 1955. As a community Credit Union, many of us were born and raised in the communities that we serve. Because of that, we make our decisions right here at the Credit Union. Some places have local branches. We have local roots. We give you the one-on-one, first name, friendly service that you deserve. Our goal is to make your life easier by offering a variety of convenient products and services that meet your financial needs. Stop by one of our seven convenient locations in Ellsworth, Box Elder, Rapid City, Hill City, Custer and Winner, S.D.
