ABILENE, Texas, Oct. 10, 2025 /PRNewswire/ -- First Financial Bank is proud to announce its participation in the first-ever Texas Banks Community Day of Service, a statewide initiative launched by the Texas Bankers Association to unite financial institutions in giving back to their communities.

"We feel honored to a part of the Texas Bankers Association's first Day of Service," said David Bailey, President of First Financial Bankshares. "Community service is at the heart of who we are.
