President/CEO Dorothy Voorhees said the branch represents the credit union’s “dedication to support a growing Box Elder community.”

The building’s design mimics an airplane hangar, paying homage to Sentinel’s roots on Ellsworth Air Force Base and complementing the nearby South Dakota Air and Space Museum. It includes a mural by local artist Aaron Pearcy, which showcases the history and impact of Ellsworth Air Force Base and the Box Elder community.

“We take great pride in our origins on base and in honoring the legacy of those who have served, protected and contributed to this community,” Voorhees said. “The Liberty Branch represents not just an expansion of our services, but also a symbol of our dedication to being a trusted financial partner — one that stands strong and unwavering, just like our Sentinel name suggests.”

NCUA data showed Sentinel had seven branches and other locations Dec. 31, unchanged from a year earlier.
