Reliabank North location is a full service bank with Reliabank Insurance Agency and Big Sioux Wealth Management on-site.

Reliabank Watertown opened in 1997 and started out as a revamped modular home with a teller line, offices, and a vault while the new site was built. The new building opened in 2000.

To fulfill Reliabank’s commitment to providing the latest in banking technology, we have installed an instant issue debit card machine on site. Instead of waiting days or weeks for a new debit card, we can provide one the same day you open an account! This is just another way we are committed to our customers.

Our employees are active in many Watertown organizations, including the Watertown Chamber, Kiwanis, Rotary, United Way, and Watertown Home Builders Association. We also have volunteers who assist in youth sports and Junior Achievement.

Reliabank is a proud sponsor of the $5,000 cash prize given out each summer in conjunction with KXLG radio’s “99 Days of Summer” promotion. Our Reliabank Grill Masters fire up the grill and serve lunch to over 200 Watertown teachers during in-service in August as a “thank you” for their dedication to our children.

While Reliabank remains a local bank dedicated to personalized customer service, we’ve always been committed to instituting new technology and changes to meet the needs of our customers. You can rely on us.
