But McNulty, who joined Goldman straight out of the Wharton School of Business in 1980 and helped build the firm's thriving private client business, says investment banking can be wearing. "It's an intense business," he says. "It's kind of like pro sports." The son of Irish immigrant parents, McNulty joined Goldman as part of its private wealth management group in Philadelphia, before stints in merchant banking, investment banking and asset management in Goldman offices from Miami to Hong Kong. Now blessed with a life of leisure, McNulty plans to spend time with his family, drive his sports car and work on a family foundation that will fund work on topics including "choice in education" and moral dilemmas created by applications of genetic research in areas such as cloning and testing. "I'm interested in the whole ethical wrapper in dealing with issues created by this research," he says. McNulty will also take on a few projects for Goldman. "Retirement is a word that I can't put my hands around," he says. "But it's not like I'm going to be hitting the beach."
