9 Guys and
a Cigar Box
In 1949, nine determined Montana refinery workers gathered in an empty box car, to pool their hard-earned cash in a humble cigar box. It’s hard to imagine they could have known the impact they would have on the lives of so many members today.

Who We Serve
Membership is available to individuals who live, work, worship or attend school in our field of membership of forty counties in Montana and nine counties in Wyoming, or are a relative of an Altana member. We’re ready to welcome you with a smile, chat about money, and serve up friendly advice!

Community Impact
Altana’s impact is seen through our passion for volunteerism, and our personal and organizational hands-on support we proudly deliver as a credit union to make a difference in community outreach, financial education, school partnerships, and community sponsorships.
Join Altana for your Journey.

Our free and completely community-driven
Altana Ice Cream Bus
A couple years back, we asked ourselves how to deepen our connection with the members and communities we serve. Our answer resulted in an actual vehicle – in our case, a 1979 V.W. bus!
- The Altana ice cream bus visited 98 community events in 2024. 🍧
- 25,636 sweet treats were given away from the bus in 2024! 🍦
