About Us

Oklahoma State Bank is proud of its tradition of local ownership and management. For over 90 years OSB has served our local communities with solid banking leadership and a focus on the needs of our customers.

The main office of the Oklahoma State Bank is located at 122 South Hoy, Buffalo, OK 73834 and we are fortunate to have a branch at 507 North Main in Gage, OK 73843. The two locations give us the opportunity to serve the communities of Harper and Ellis counties.

Our staff consists of 18 of the finest people you will ever meet. You will find our employees, officers, and directors active in every civic event and most are in leadership roles in their churches, civic clubs, and school systems.  At OSB we feel that we are experiencing a period of positive and steady growth and at the present time we have over $60 million in assets.

Oklahoma State Bank’s mission is to meet the needs of our local communities by combining time honored banking principles with a forward thinking approach that will afford our customers all of the conveniences of “Big City” banking. Our financial services include competitive loan and deposit rates, telephone banking, and internet banking.

We are excited about our new ways to serve your needs and encourage you to call one of our friendly staff in Buffalo at 580-735-2545 or Gage at 580-923-7541 and take advantage of our products and services today
