Member Stories

I was at the credit union 5 days ago and Kacie was the best representative I ever dealt with in a financial institution ... she was 100% helpful.

Nicole did a great job assisting us with the closing paperwork on our new home. She went above and beyond, by taking the time to scan and send the closing paperwork via email to the title company. She was also kind enough to make us copies of the paperwork. She made our closing painless and easy!

Fantastic service. They treated us like family when my mom passed away. They have also been outstanding when I got a car loan, home equity loan and refinanced. How can anyone not give them a great review?
