I've known Sonny since he was a purple belt. He has always had a unique way of teaching, in which he could show a technique and you then could go and use it live. There have been very few instructors that have the ability to show jiu jitsu the way Sonny does.
I have been training on and off for nearly a decade. In which I have trained amongst some amazing trainers. But I can honestly say Sonny rivals the best I've had the privilege to train with.
If you want some great training and support in the room and at competitions this is the place to go.
