Fenn has been referred to as "The Godfather of Arizona Boxing". Fenn during his time had made a huge contribution to boxing in Arizona, promoting both amateur and professional boxing. In the 1950s, the boxers he managed were golden gloveswinners. In the mid 1970s, while president of the Arizona GoldenGloves Association, Fenn encountered major problems for allowing female boxerMarion Bermudez to fight.
