Allegiance Bank Welcomes Former Post Oak Bank Customers

Today, we are excited to re-open the newly-branded doors of former Post Oak Bank sites as Allegiance Bank locations. We are proud to officially welcome our new bankers and customers to the Allegiance family. Together, we are stronger and even more committed to providing extraordinary customer service as Houston’s premier community bank.

All of our more than 500 bankers live and work in the communities we serve. As we extend our network to 27 locations, we are grateful for the opportunity to guide our customers to the full-service banking solutions they need to best meet business and personal goals.
