Mr. Hall taught the hundreds of children who would come through the doors of the Yozeum each Summer and demonstrated at the factory, in malls, summer camps, and various other local venues.
His professional association with Playmaxx/Pro-Yo brought a sponsorship for Mr. Hall to the 1995 AYYA World Championships, en route to his divisional World Championship win.
Mr. Hall was a local and regional champion in Arizona before traveling to Las Vegas for the World Championships, held that year during the International Jugglers’ Association Convention.
