LXTC, previously known as Tierney Lacrosse LLC, was founded by Bill Tierney, Trevor Tierney and Matt Brown in 2009, when the three coaches took over the University of Denver men's lacrosse program. Over the past eight years, the Denver Pioneers have gone on to reach five NCAA Final Fours and a National Championship in 2015, to build their legacy as a national power. The three men who led this emergence for the Pioneers are a few of the most accomplished coaches and players in the game of lacrosse. Bill Tierney is a Hall of Fame lacrosse coach who has won six NCAA National Championships, one FIL World Championship and coached many All-Americans. Trevor Tierney is the only goalie in the history of the game to have won a NCAA National Championship, a MLL Championship and a FIL World Championship. Matt Brown is a former professional player in both the MLL and NLL and is recognized as one of the great young offensive coaches in the game. These three bring an amazing amount of experience, knowledge and passion to the game. LXTC is built upon their dedication and life-long love for the game and its' community.

At the same time that they were building their Denver Pioneers team, these coaches began working with the Colorado lacrosse community and created multiple lacrosse programs for young lacrosse players to participate in. LXTC is the cumulation of that hard work and includes the Denver Pioneers Lacrosse Camps, the Denver Elite club lacrosse teams and the Denver USBOXLA box lacrosse teams and leagues. Through these programs, LXTC offers the premier lacrosse developmental program for youth and high school players in Colorado on a year-round basis. These programs are built upon the same building blocks that has brought the University of Denver so much success. The LXTC founders and coaches believe in running a program that is based on integrity and are dedicated to helping young men reach their full potential on and off the field. There is simply no place in the world where a player can get better instruction and guidance in the game.
