Welcome to TX! There are three main clubs that I am aware of: The Cap and Hare
in Fort Worth, Knights of the Brown Bottle
in Arlington, and North Texas Homebrewers Association
in Dallas. I am a member of NTHBA. Most of the meetings are held in north Dallas (Plano, Allen, etc.), so for Mansfield, you might want to look at the other two. Happy brewing!
