JJ Machado - excellent, very detailed, very friendly, and very funny. Rolls with everyone after most seminars and barely breaks a sweat
Pedro Sauer - (My instructor) - amazing understanding of the technical details... very friendly outgoing guy, always says nice things about everyone! Can't recommend him enough!
Rey Diogo - very good BJJ, also bends over backwards to make you feel welcome. Highly recommend private lessons with him if you're in LA.
Eddie Camden - BB under Pedro Sauer - very technical, very good understanding of the body and leverage. Produces excellent fighters (MMA and BJJ)
Jorge Jimenez - BB under Pedro Sauer - very technical, has a small guy's aproach to jiu jitsu. Very friendly as well
Erik Paulson - more Combat Grappling than strictly BJJ, but very fun experience training with him.. very knowledgeable, technical, & funny!
