In 1988, Tierney accepted the position as head coach of the Princeton Tigers. He acquired a program that was underdeveloped, and quickly turned it around. Tierney's Tigers won six NCAA championships (1992, 1994, 1996, 1997, 1998, and 2001) in nine years, and have appeared in eight NCAA championship games, nine NCAA Final Fours and 11 Ivy League championships.
