About Texas National Bank

The Texas National Bank Difference

Known originally as First National Bank of Mercedes in 1920, the bank changed its name in 1985 to become Mercedes National Bank. Business continued under that name until early 2006. In May 2005, MNB Ventures,
Inc. purchased Mercedes National Bank. It was this purchase that brought the name change to Texas National Bank.

With the high economic growth that Edinburg has experienced over the last few years, it was decided to open another Texas National Bank location. The Texas National Bank in Edinburg opened in 2007.

Texas National Bank prides itself on knowing the community – not just the needs of the community but the people living within that community as well. Texas National Bank utilizes state-of-the-art equipment, but it’s the people we hire who are able to make each visit a positive experience. Our staff is committed to treating customers right and providing them with the highest quality customer service.

Along with all of your basic banking needs, Texas National Bank also handles:
