Although Jack hones his skills by competing in tournaments, his strength and true passion is teaching others. While many martial arts instructors hold various jobs during the week and teach only in the evening or weekends, Jack makes his living training others. It is all he does, and it shows in his students --many of whom have won jiu-jitsu and submission tournaments.
