Lifetime Experiences & Unbreakable Bonds

Mission: Our mission as a program is to teach players attitudes, behaviors, and skills that they can use on and off the field. We believe that lacrosse is an incredible way to harness life lessons, and personal development is at the forefront of our curriculum.

 The Rattlers blueprint contains three pillars- Character, Commitment, and Family. We believe that these pillars, along with the specific behaviors that go along with them, dictate success in lacrosse and all aspects of life. We emphasize the blueprint regularly, and reinforce it through numerous character workshops and leadership seminars throughout the course of the year.

Family: Family is not just something we say- it is something we believe, and something we do. We want all players, parents, and family members to be part of the Rattlers Family and build positive relationships among players and families that span much further than the lacrosse field.

Skill Stratification System (S3): We have a 100+ page curriculum that dictates rapid player development, age specific learning, and includes teachings from some of the top lacrosse minds in the world.

Giving Back: Volunteer work and community projects are a major focus for us. We want players to understand the importance of helping people in need, and being part of a community. In addition to practice and games, teams are given a volunteer projects to complete. We feel that this is a great way to instill compassion and empathy in players, and give them real world experience that will benefit them in school and future careers.
