As a teen Don also trained extensively in Shotokan Karate, Kenpo Karate, Tae Kwon Do, Boxing, and Okinawa weapons .  In 1973 after winning the Brown belt division at the Western Canadian Karate Championships in Regina Saskatchewan at age 17, Don was awarded his Black Belt by Lindon Bateson (his instructor at that time), Ed Bateson, Dwight Sheer and Emil Repack, 4 of the top Martial Arts instructors in Canada.  At age 18 Don defeated World Martial Arts Champion Alex Kwok of Hong Kong.  In 1976 Don trained with Marine Force Recon Sensei Coffen in Hand-to-Hand combat and Kickboxing.  In 1979 Don opened his own Dojo and called it Tomari after the Okinawa city Tomari that historically allowed various fighting styles to train together. 

The Tomari training has proved very effective not only for self-defense and physical conditioning but also in the ring.  Don's Tomari Dojo has produced 4 Professional World Champions, 8 World, 10 North American and 12 National Amateur Champions in kickboxing.  Don has been honored with the Instructor of the year award from the World Kickboxing Association.

Don spent two years receiving guidance in boxing from Boxing Hall of Fame Legend Eddie Futch, trainer of 21 Pro Boxing World Champions as they co trained Don's student, Pro boxing Canadian Heavyweight Champion Shane Sutcliffe.  Don has now incorporated the training and fighting methods of Mr. Futch in what he teaches.  In 1998 Don personally trained Elite Commandos from the US Forces and has twice been invited to war torn Beirut to train Special Forces.
