About CFS


We've recently learned that a former student of C.F.S, Juan "Sergio" Lebron, is attempting to recruit students with the intent of teaching techniques he has learned with us. While we are concerned about someone profiting from something we've worked so hard to build, the bottom line is that this person is not at all qualified to teach C.F.S. and we believe someone will get seriously hurt.

Juan completed only the first year training at C.F.S. (a fundamentals level) and was asked to leave and not return to the class because he displayed various behaviors not at all appropriate for a C.F.S. fighter. Enough said.

If you have an interest in learning a mixed martial art like C.F.S., we suggest that you first audit a class and afterwards speak with the instructor and students. Never begin training in a full-contact fighting system without knowing the background of the instructor and the level of intensity involved in a class.
