He moved up to a club team, the Northern Kentucky Piranhas; took another step up, to the Cincinnati Marlins, which featured Olympic gold medalist Mary T. Meagher; and finally landed at the University of Cincinnati from 1980 to 1989.

Busch has won every conceivable award in American swimming. He has been named NCAA Coach of the Year several times. The USOC swimming Coach of the Year. He has been head coach of the USA World Championship team. Fifteen of his current and former UA swimmers competed at the Beijing Olympics.
