Denver head coach Bill Tierney announced on Thursday night that he would be retiring following the 2023 season.

Terry Foy of Inside Lacrosse first broke the news earlier Thursday evening.

The 2023 campaign will be Tierney’s 14th with the Pioneers and 42nd overall as a head coach in the college ranks.

“They say, ‘When you know, you know,’ and as my career draws to a close, I’m at peace with this decision,” Tierney said in a press release.

During his years as a college head coach up to this point, Tierney has compiled an overall record 429-147. That includes 30 trips to the NCAA Tournament, 25 trips to the Quarterfinals, 15 Championship Weekend appearances, and nine appearances in the national title game.

Prior to arriving at Denver ahead of the 2010 season, Tierney guided the Princeton Tigers for 21 seasons. During those years, he brought the Tigers to national prominence and led them to six national champions (1992, 1994, 1996, 1997, 1998, and 2001). The Tigers were runner-up and semifinalist twice under Tirney.

At Denver, Tierney has led the Pioneers to 10 NCAA Tournament appearances. That includes five Championship Weekend showings. Tierney guided Denver to the program’s first national championship in 2015.

He also took RIT to the NCAA DIII Tournament in 1983 and 1984, and helped guide Johns Hopkins to two national titles in 1985 and 1987 as an assistant coach.

Tierney was inducted into the National Lacrosse Hall of Fame in 2002.
