Our History…

First Security Bank established its charter in 1916. The original location is in the heart of Beaver, Oklahoma, located at 15 South Douglas. In 2023, First Security Bank expanded, opening its second location in Southeast Texas at 8350 Phelan Boulevard. First Security Bank is an independently-owned “home town” bank, committed to investing in the communities in which it serves. First Security Bank is a community bank with directors, officers, and employees who, for over a century, have been committed to serving the needs of our customers.


First Security Bank believes that a community-minded spirit, with a focus on developing quality relationships, are the two most important attributes of a bank. First Security Bank’s goal is to give our customers superior service in a warm and friendly atmosphere.

Each day our world is becoming more technically advanced. The same is true of banking. However, at First Security Bank we want our customers to know that no matter how advanced we become, you will never be just an account number to us.
