The Gateway Story

Gateway Bank represents a return to how banking used to be, where the staff knew everyone by name and treated customers like people instead of numbers.

We bring this nostalgic approach into modern times and offer the best of both worlds: the fast, personal service of a local bank, along with the convenient, secure products and services of a large one.

Our core values and passion for serving the community drive everything we do. When you work with us, you’re treated like family, receive the one-on-one attention you deserve, and feel good about supporting a local business.

While our Arizona community bank is located in Mesa, our service extends far beyond. With a large network of fee-free ATMs, plus added conveniences like a mobile app and Remote Deposit, you can experience the Gateway difference no matter where you are.

Kind words from our customers

Gateway Bank doesn’t just say they want to help. They have set up their operations and team to actually do it.

– Pastor Cunningham, SouthGate Church
