He started Goldline, Inc. in 1982 which sold BMX products at bike shops and on the national circuit.
John built ABA tracks from 1982-1985 on the lo-cal and national level and is credited with creating many of the rules that govern BMX racing and shaped the sport of ABA BMX. John also created the first contingency program which allowed professional racers to earn a living. After serving as vice-president of sponsorship and marketing, John became the ABA President in 1985 and served in that capacity until the end of 2008.
