Teaching Professionalism

One thing that stands out about the Smash Gyms instructors is the professionalism in which they conduct themselves.  Anyone who have been involved in martial arts for a long time and traveled around to different schools can attest that this is  a quality that is often lacking by many instructors.  Check out this short video where Smash Gyms Sunnyvale Head BJJ instructor Michael Jen talks about this subject.
