Sensei Zack Stewart (4th Dan) began training karate over 20 years ago.  His focus in Shotokan karate began with training under Sensei Allen Renfrow in his hometown of Owensboro, KY.  Following a move to Los Angeles, CA Zack sensei trained with Sensei Avi Rokah and the late Master Hidetaka Nishiyama, Co-Founder of Japan Karate Association (JKA) and a student of Gichin Funakoshi, Founder of Shotokan karate.  This direct connection to the father of modern karate has allowed Zack sensei to train in one of the purest forms of traditional karate – something he is passionate about continuing with his own students today.

Following his time in CA, Zack sensei relocated to Nashville, TN and has since trained with Sensei Anthony Milevsky, Sensei Steve Ubl and Sensei Richard Amos.  Zack sensei was also the first American to complete the WTKO Kenshusei Program (Instructor's Training) at the WTKO Headquarters in NYC under Sensei Amos in the winter of 2015.  

Zack sensei has been teaching Shotokan karate for over 15 years, serves currently as the US National Director of the World Traditional Karate Organization (WKTO) and is an official Examiner, Judge & Instructor with WTKO.  He resides in Nashville, TN and teaches classes for both adults and children at his dojo, Traditional Karate Nashville.


Through the training of Shotokan Karate and it's emphasis on intelligent body movement, practical applications and self-discipline, Traditional Karate Nashville promotes both physical and mental well-being for students ages 4 and up.
