Roy Cantu – Owner & Head Instructor – Black Belt with Blue Bar, 2nd Dan

Born and raised in Northwest Houston, I started jiu-jitsu not long after its introduction into the US. Always having an interest in athletics and problem solving, jiu-jitsu presented both with a lot more to offer. It wasn’t until I met Mr. Valente that I learned the true meaning of Jiu-Jitsu and what it truly represents which was not just a self-defense martial art, but also a lifestyle. I found something that made me feel alive and energetic. I was working a very stressful job and jiu-jitsu gave me an outlet, gave me tons of energy and made me feel strong and confident. I’m in the best shape of my life and Jiu-Jitsu is my passion. I am also a dedicated family man. I married my high school sweetheart and together we have 2 wonderful children.  Roy, Jr. “R.J” who is currently enrolled at the Bauer Business School at the University of Houston and majoring in Finance.   Our beautiful daughter, Skylar who is currently a freshman and is currently enrolled at Lonestar Community College and hoping to soon be a Coog!
