Anyone involved with sports can tell you the importance of teamwork. Greg Zipadelli is the perfect example of teamwork. As the only crew chief NASCAR driver Tony Stewart has ever known in the Sprint Cup Series, Zipadelli has become the backbone of the No. 20 team. Zipadelli has lead Stewart to 32 wins, as well as two NASCAR Sprint Cup championship titles. While a successful career is important to Zipadelli, it is the time he spends with wife, Nan, and their two children, Zach and Elli, which he looks forward to the most.
