Membership

Ownership makes the difference: Become A Member!

While there are several factors distinguishing credit unions from other financial institutions, we believe the primary difference is ownership. Sentinel Federal Credit Union is owned by the members, and each member has a voice on how the credit union is run. Doesn�t it just make sense to do business with the business you own?

You are eligible for membership at Sentinel Federal if you live, work, worship, or go to school in, or are a business or other legal entity located in the counties of:

Pennington
Lawrence
Meade
Custer
Lyman
Todd
Tripp
Gregory
Mellette

We�d also like to remind you that your family members are eligible to join. This includes your mother, father, brother, sister, aunt, uncle, cousin, foster children, adoptive children, step-children, and grandparents.
