We provide premiere box lacrosse training, competition, and coaching. Players will develop, improve, and excel through the program’s competitive team-focused concepts in box lacrosse, while being coached by past and present professional players and coaches who’ve excelled in the sport at the highest levels.

We are Massachusetts' home of REAL Box lacrosse! Mass Box offers Middle and High School Leagues as well as high level box lacrosse travel teams (Honey Badgers LC) that play in premiere box tournaments wherever they may be. Select teams that train, travel and compete at the best box lacrosse tournaments we can find.

MassBox was born with the goal of fostering REAL Canadian style box lacrosse and developing the game in New England's premier $25mil state of the art indoor facility.  Our home is Boston Sports Institute(BSI), which is centrally located on Rte 9 in Wellesley, MA. Coached by former pro and collegiate players that are accomplished coaches and love sharing their experience to the next generation of box players. 

Players from all towns, teams and clubs are welcome to come join the fun and learn a part of lacrosse that will differentiate them and help them reach their individual lacrosse goals!
