[7] The University of Denver first began sponsoring men's lacrosse as a club sport in 1966 under coach Pete Richardson.

Over the next 24 years, the team would alternate between varsity and club status in the RMLA, a member of the US Lacrosse Intercollegiate Associates (USLIA).

After winning the GWLL outright in 2006 with a 5–0 conference record, Denver earned a bid to their first NCAA Tournament, where they would fall 16–8 to Maryland.

Two years later the Pioneers again shared the GWLL regular season title with Notre Dame and Ohio State, but earned an at-large bid to the 2008 NCAA Tournament with a 10–7 overall record.

Munro finished with a 90–70 record as head coach of the Pioneers, securing four GWLL Championship titles (2003, 2005, 2006, 2008) and two NCAA postseason tournament appearances (2006, 2008).

In the quarterfinal round Denver defeated Johns Hopkins 14–9 at James M. Shuart Stadium in Hempstead, New York to earn a spot in the NCAA Final Four.

Denver would go on to lose to Ohio State in the ECAC title game, but the Pioneers would earn an at-large bid to the 2013 NCAA Tournament.

In the first round Denver would host just the second NCAA Tournament game held west of the Mississippi at a sold out Peter Barton Lacrosse Stadium.

In the quarterfinals, Denver faced a rematch of a 2011 first round game against North Carolina, this time at Lucas Oil Stadium in Indianapolis, Indiana.

In the Pioneer's second semifinal appearance in three years, Denver would fall to Syracuse 9–8 at Lincoln Financial Field in Philadelphia, Pennsylvania.

It is the first collegiate stadium in the nation to be designed solely for lacrosse, and is home to DU men's and women's lacrosse teams.The north-facing stadium can accommodate approximately 2,000 people and features pre-cast concrete bench seating, locker rooms for men and women, public restrooms, a concession area, viewing pavilion/conference room and a two-direction press box that also serves the soccer field to the south.

Other prominent donors were John and Anna Sie, and Myra Levy, whose family used to sell concessions at DU football games.

DU is 76–14 all time at Peter Barton Lacrosse, including 45–5 under Coach Bill Tierney, and 21–4 in sellout games.
