At Stanford, he partnered with three doubles players who later reached the top five in the world: Scott Davis, Jim Grabb, and Patrick McEnroe.
He reached a high of #244 in the world in singles achieving most of his success on the ATP Challenger Tour including the semifinals of Manchester (1989) and San Luis Potosí (1988) and the quarterfinals of Nagoya (1988) and Dublin (1989).
