Third Coast Bank was established in March of 2008 by a group of local organizers seeking to create a relationship oriented bank committed to personal service and community contribution. We distinguish ourselves by anticipating and exceeding the expectations of our customers, building sustainable partnerships, maintaining the highest standards of ethical business conduct, being aware of and responsive to the needs of our community, and always being mindful of the fact that customers have a choice.

Our approach is to be the best bank by offering the latest, state of the art technology, sophisticated banking tools and products including a high tech suite of treasury management solutions with our personal touch and community banking service. We know it’s personal to you, that’s why our relationship bankers will always be available to talk to you.

Third Coast Bank is publicly traded under the ticker symbol, TCBX, on the NASDAQ Global Select market and has kept its grassroots values and entrepreneurial spirit. Our employees are empowered to do the right thing and encouraged to make a difference in our communities. It has been said that we are the “grease in the economic engine” as we have helped numerous businesses grow and profit. Those profits allow our customers more freedom for “doing good in their communities.”

Growing Communities.
