Due to COVID quarantine guidelines and limited staffing, there may be times when our bank lobbies are available by appointment only. We encourage you to take advantage of the range of services available through Online Banking or through our Mobile Banking App. If you would prefer to speak to a banker or schedule an in-person appointment, please give us a call at (918) 491-9700.

Grand Bank

Welcome to our bank, one you may find is a little unique. After all, you won’t come across Grand Bank on every corner, or see this family-owned business on billboards or tv.

Instead, what probably brought you here was a different form of advertising: word of mouth. Maybe it was something said by a Grand Bank customer, someone working to help their community thrive. Or maybe it was one of our great bankers, someone dedicated to serving such people, the kind of people who get things done. We hope we can serve you in the very same way.
