Gracie self defense, Rickson Gracie (invisible) principles, and great instruction make this the school to go to.
I learned more at KJJ-ATX in 3 days then what I learned at a sport oriented BJJ school. Ken DaSilva is an excellent Brazilian Jiu-Jitsu instructor, a consummate professional, and can flawlessly deliver instruction making it comprehensive to any one. Best BJJ style ever!!!
