Stronger Together. 

On the weekend of September 4, 2020, we are acquiring four current Vast Bank locations--Catoosa, Owasso, Collinsville, and Oologah. We are thrilled to join these communities and are honored to be your trusted banking partner. 

As we transition these four locations to Armstrong Bank, we want to reiterate our fierce commitment to you and to ensuring your transition to the Armstrong family is seamless.

At Armstrong Bank, we build strong communities and aim to provide the high level of service our customers deserve and have come to expect from us. If you have any questions throughout this transition from Vast to Armstrong, please do not hesitate to contact us by calling 918-709-7400
