Oklahoma’s Original Bank
Founded Alongside Ardmore
Established just two years after the City of Ardmore was founded, 1NB launched the first bank in the city and eventually what would become the state of Oklahoma. Growing with the city from its infancy, we helped our earliest residents and institutions get their start.
Helping You Through it All
Through Ardmore’s good times and its challenges, we have stood by our city and our people. Following two local disasters, our bank provided support and dependable service to our community.
Onward and Upward
As the city continued to grow, 1NB’s primary branch moved into its current location in the heart of Ardmore to provide better accessibility to local businesses and residents.
Expanding Our Community
The growth of 1NB progressed in the 1990s with a booming period of expansion across southern Oklahoma with the addition of new locations in Ardmore as well as several new branches extending essential banking services to surrounding communities.
1NB Today and Looking Forward
“Our leadership is committed to the development of new leaders for the future of our bank and our communities. We will continue to promote the economic growth and stability of the communities we serve by providing high quality, competitive financial products and personalized, customer-oriented service.”
