Tierney served as an assistant coach at Hofstra from 1995 through 2000 before leaving for a similar position at his alma mater Johns Hopkins University. During his six-year tenure as an assistant, Hofstra recorded six consecutive winning seasons with a combined overall record of 61-28 and a conference mark of 29-2, captured five league titles, received five top 15 final national rankings, and played in four NCAA Championship tournaments.
 
Tierney returned to Hofstra after a six-year tenure at John Hopkins, with the final two seasons as associate head coach. As the Blue Jays offensive coordinator, he was the architect of one of the most potent and explosive offenses in the nation. Tierney directed the Blue Jays attack that finished second in the nation in scoring margin, sixth in scoring offense and 16th in man-up offense during Hopkins' NCAA title run in 2005. The Blue Jays led the nation in scoring offense and man-up offense in 2003 and finished fifth in both categories in 2004.
 
In Tierney's final season at Hopkins the Blue Jays posted a 9-5 record, advanced to the NCAA Championship quarterfinals, and ranked in the top 15 in the country in four statistical categories.

Tierney played for the Blue Jays from 1988 through 1991 and served as team captain as a senior.  He helped lead Hopkins to the NCAA Tournament in each of his four seasons, including an appearance in the 1989 NCAA title game. He received Hopkins' Turnbull-Reynolds Award as a senior as the player most exemplifying leadership and sportsmanship. Tierney was also selected to play in the North-South game as a senior.
 
After graduating from Johns Hopkins, Tierney continued his playing career by playing three seasons of indoor lacrosse for the New York Saints before serving as an assistant coach for the Saints for two seasons.
