"This is not a "sport" jiu-jitsu academy. It is a self-defense Jujūtsu school in the Spring area owned by Black Belt Calvin Carter. This school teaches the same Valente Brothers system which is based in North Miami Beach, Florida. We are fortunate to have 2 Valente Brothers-affiliated self-defense Jujūtsu schools in the Texas area. The other school is located in the northwest Houston, Copperfield area. (I have a review for that school as well). In any case, because both schools are affiliated with the Valente Brothers, my husband and I have had the privilege of working with both Black Belt owners and helping at both schools for privates and group classes. At Katana, we have witnessed Calvin Carter as both an amazing teacher and person. He is an excellent representative of the incredible 753 code and philosophy taught by the Valente Brothers. Mr. Carter is regarded highly and respected for his knowledge and passion for Jujūtsu as more than a martial art, but a lifestyle. HIs school is growing and is both professional and welcoming. There is a wonderful kids and adult program. My husband and I, as well as our kids, are truly dedicated to this awesome program and highly recommend that you and/or your kids try it. You will love it!"
"I was 1 month postpartum when I joined to learn Jiu Jitsu here. I’m only growing stronger mentally and physically. Great masters, patience full and understanding environment."
"My daughter is almost 12 years old now and has been going to this Academy since she was 6! I love the instructors !!! The level of confidence my daughter has right now is more than I could count on :) . They have after school classes all year long and provide fun camps during the summer . I’m so thankful that we live not too far and they keep my daughter interested to go on for so long ! The World is upside down right now and JiuJitsu skills is something that anyone should have nowadays. Thank you Marcia and Calvin Carter for your dedication to community and sharing such voluble skills with our kids from the bottom of my heart !!!!"
"Great environment. Kids and adults friendly. My kids take classes with Mr. Carter for over 4 years and I have seen their confidence and self esteems build up. I recommend to any parent looking for life changing skills. Me and my Husband have also enrolled in the program."
