Mark Hacker

Mark's appreciation and love for martial arts began in 1982 when a co-worker, started teaching Sereff Taekwando and needed students to fill out his class. He agreed to take a few classes, at first just as a favor to a friend, but was soon hooked.

He started jujitsu as one of Johnny's first class of students in 1998. Since, he has earned a 2nd degree black belt in both karate and jujitsu, and enjoys sharing his knowledge and experience.
