He is a former International Karate Champion (he beat both Joe Lewis and Chuck Norris in a single evening in 1966) and a trainer of many national champions. Grandmaster Steen was one of the first martial arts business entrepreneurs building a chain of schools across the Southwest in the late 1960s and early 1970s. As Mr. Yates’s teacher he is a valued advisor to the AKATO.
