Sentinel Federal Credit Union and FiiZ Drinks of the Black Hills are excited to announce a new partnership that will bring FiiZ’s popular specialty sodas, custom drinks, and treats to the Box Elder community.
Veteran owned, FiiZ Drinks of the Black Hills will open a new location within the Sentinel Federal Credit Union building at 441 N. Ellsworth Road, with a planned opening date of September 12, 2026.
The addition of FiiZ reflects Sentinel’s ongoing commitment to supporting local businesses and enhancing the experience of members, residents, and visitors in the rapidly growing Box Elder community.
“As Box Elder continues to grow, we’re excited to welcome another business that will add energy, convenience, and value for our members and the community,” said Dorothy Voorhees, CEO of Sentinel Federal Credit Union. “Supporting local entrepreneurs and creating opportunities for community connections align with our mission and our commitment to the area we serve.”
Known for its customizable specialty sodas, flavored waters, energy drinks, and sweet treats, FiiZ has built a loyal following by offering hundreds of unique drink combinations and a fun customer experience.
“We’re thrilled to bring FiiZ to Box Elder and partner with Sentinel Federal Credit Union,” said Jen Havenner, owner of FiiZ Drinks of the Black Hills. “This community continues to grow, and we look forward to becoming part of that growth while serving residents, military families, and visitors throughout the region.”
The new location will occupy retail space within Sentinel’s Liberty Branch, which opened in March 2025 near the main gate of Ellsworth Air Force Base. The partnership represents a shared investment in the continued growth and vitality of Box Elder.
Additional details regarding grand opening celebrations, special promotions, and community events will be announced in the coming weeks.
