I would look at the Academy of Modern Martial Arts (AMMA) and try Judo. She can try it out for free to see if she likes it.
The instructor is Bob Perez also the A&M Judo coach and coach of USA Judo World games. AMMA is great and easy to deal with. They are located right next to Little Caesars Pizza on SW Parkway & Texas Ave.
My daughter did Judo there for many years and she loves it. There is no pressure to do competitions, you can if you want. They do not have crazy belt testing fees (you just pay for the physical new belt, less than $10). It also takes a while to get promoted in Judo versus some of the other Martial Arts. But if you receive your belt from Bob, then you earned it.
AMMA, offers other types of martial arts too. I am promoting Judo; but, she may like something else. Have her try a couple of different classes to see what she likes. AMMA will let you do that. Even the monthly fee lets you do all the classes; maybe take Modern Arnis (using weapons), or Taekwondo.
