I've seen this question a lot on this forum and I always wonder the same thing. Is there a reason not to train with Carlos for BJJ if you have the opportunity? Everyone else here is basically a student of his minus Mohler who is under Jacare now I think, but I never thought he was all that great of a teacher compared to others around.
I mean I understand if you are looking more for No Gi or looking for MMA, then other places make more sense, but for straight Sport BJJ it's hard to argue with the Machados ability to teach that.
I liked training with Big O (Orlando Waugh) over at Texas Self Defense Academy since we have similar builds, but I've heard he's gone to a new business method that kinda makes it hard to do that old laid back BJJ style thing. I haven't been over there to see though.
My daughter likes training with Kathy Brothers in her kid classes. Apparently she has moved from doing kid's classes at Carlos' school and is at Guy Mezger's Lion's Den/FS Martial Arts school now. I am planning on taking her up there in the next week or so and trying out Kathy's class for her and their adult classes for me. But I really liked it when Kathy was at Carlos's school so I could go and work out with the man right after my daughter's class.
