This guy is not a BJJ guy. Simple. He has never trained in BJJ. Period. He refers to it as "Gracie wrasslin" and does something that looks like aikido mixed with pressure points. Funny, though, he adds himself on all types of BJJ forums as a BJJ black belt.

I think the guy above me has his people confused. I have trained with Master Dave for over a year in BJJ. He teaches fairly accurately and passes on information very well. I have never done pressure point in any of the classes he teaches and no akido locks in the bjj class. His bjj classes will prepare you for a self defense situation and he will take the time to get you ready for a competition if you seek his assistance.

Red hair, overweight, nasally voice, with his academy off of San Juan by 17. He never gave me a straight answer regarding his BJJ belt or instructor, but told me that he "has done martial arts for over 30 years and does not need an instructor." He would not let me participate in the group instructional class, much less roll with me. I merely question his credentials and was not impressed with his teaching at all.

The so called "master" is a joke, I've trained with real BJJ instructors and this guy is not one, his claim of holding a black belt in any form of jiu jitsu is a bold face lie. I cannot stress his money hungry and unskilled attitude. The man is down right strange and awkward coupled with a side of creepy. Roll with him "if you can get him to", talk to him, compare it with other confirmed instructors and tell me he is anything but a fraud. I trained with him for about 6 months and from the moment I talked to him I was apprehensive of giving him any of my money. I have a good judge of character and this man screams CHEAT and WANNABE. I say these things not for any benefit of my own but for those who do not know any better or haven't found the right school yet. Please look another way, and don't be fooled by this man.

After hearing about him possibly being a fraud, I sent him a friend request on Facebook. He accepted it. I posted on his wall asking "from one bjj black belt to another, who did you get your bjj black belt from?" He deleted the post and unfriended me. I guess that answers that. Any legit bjj black belt would be proud to answer that question.
