Our History

Our beginnings are quite humble. When our great state
turned the corner from territory to statehood in 1907, we
too began our existence as The Groves National
Bank of Hollis, Oklahoma. 

As the years passed, the name of our bank evolved and
the area we served began to grow. But our roots in friendly, community banking remained the same. In time, our
territory added banks in communities across
Oklahoma and Texas.

You + Great Plains Bank = The Perfect Pairing!
Our products and services were designed with you in mind! We make banking simple and convenient every step of the way!
