Become A Member

As a community Credit Union, we’re not-for-profit, and owned by our members. As a result, we usually offer better rates and less service charges than your ordinary, everyday bank. Over there, you’re just another member. With us, you’re an owner! Join today.

We are a better way to bank. Call, click or stop by to visit us.

Who Can Join

You are eligible for membership at Sentinel Federal Credit Union if you live, work, worship, or go to school in, or are a business or other legal entity located in the following South Dakota counties: Pennington, Lawrence, Meade, Custer, Lyman, Todd, Tripp, Gregory and Mellette.

Every member is an owner with an equal vote in the election of the Credit Union’s volunteer board of directors. Once you become a member of Sentinel Federal Credit Union, you can remain a member for life, even if you change jobs, relocate or retire. Plus, after you become a member, your immediate family members are automatically eligible to join.

We require an initial deposit of $5. This initial deposit represents your share ownership. It is not a fee; it goes directly into your newly established Share/Savings Account.
