Yes. I don't particularly adhere to one style, seeing as how my instruction was based on "if it works, then you use it; screw the rest." All that means is that I'm a mixed martial artist, and I must be damn good at it, if I make a living out of teaching it. The styles under my belt (hahhaah, get it, belt?) are Gracie/Brazilian Jiujitsu, Muay Thai, Kung Fu, and Judo.
