Old post, I know, but hey, I wanna put down my experience too.
Some Brazilian Jiu Jitsu under Cesar Gracie's acadmey in Pleasant Hill. He's trained Nick Diaz, Jake Shields, and Gilbert Melendez to name a few.
My instructors were
Sergio Lourenco and
Vinicius Magalhaes.
I also did an introductry class with
Enn Fairtex over at Fairtex San Francisco. Top notch guy.
Very patient with me dispite the fact that I was overweight, slow, and didn't know how to jumprope. Not good for a Muay Thai student.
