David McKenzie, Jr.

Mr. David McKenzie started his martial arts career with Judo in 1978. He soon switched to Bill Shaw Karate, then eventually to Tae Kwon Do. By 2002, Mr. McKenzie was awarded his 5th-degree black belt by his mentor, Mr. Ford. He also has a blue belt in Jiu-Jitsu. Mr. McKenzie has been teaching Tae Kwon Do since 1987, and believes that the most valuable element gained from his martial arts experience is the confidence to know that "one owns the ground they stand on." His personal philosophy is that everyone has both their own limitations and strengths, making it impossible to expect uniform methods and results. Mr. McKenzie is currently the head of the Western Tae Kwon Do Karate Association.
