Altana is the best place to do business when looking for a smaller place then a big bank. The services they offer just like the big banks yet in a more convenient way. They are more personal and friendly. Your not just a number at Altana they treat you like family. I highly recommend them if you want a smaller financial institution. I've have been dealing with Ginnette for over 30 years. When employees stay to me it says it's a great place to work.

I walked into this bank for the first time because I was interested in opening an account. The front desk staff told me to wait a moment, as someone knowledgeable in this area would come to provide consultation. After waiting for a while, someone approached and called me in to speak in a room. However, after just the first question I asked, that person responded with a single word: "I don't know." I immediately realized that they had no knowledge about this matter at all. It was a huge waste of time, and I don't intend to use their services here at all.just being honest.

We have had three loans at Altana. Ryan Cox has been amazing with every loan. We live in Great Falls and Ryan has went up and beyond to help us. I recommend Altana to anyone!

I had a fantastic experience with Altana Federal Credit Union, and I especially want to recognize Ginnette for her outstanding service in helping me secure my car loan. From start to finish, she was knowledgeable, professional, and genuinely invested in making the process as smooth and stress-free as possible. Ginnette took the time to explain all my options clearly, answered every question I had with patience, and made sure I understood every step of the process. Her communication was prompt and friendly, and I felt supported the entire way. Thanks to her, I was able to get a great rate and drive away feeling confident in my decision. If you're looking for a trustworthy credit union with amazing staff, I highly recommend Altana—and definitely ask for Ginnette!
