Details
Mission: Our mission as a program is to teach players the attitudes, behaviors, and skills they can apply both 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.
Character. Commitment. FAMILY.
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.
We pride ourselves on having the best coaches in the state! All coaches are trained in our curriculum, and the majority of coaches have high-level playing and coaching experience. We choose to coach through inspiration and rewarding excellence rather than demanding and obedience. We lean on the Rattlers Blueprint of Character, Commitment, and Family to guide our teams to be Better Players and Better People.

Tryouts
ALL PLAYERS MAKE A TEAM. Tryouts are only for the top team of each age group.
Spring Tryout Format - We do not have a formal tryout for this spring season; however, we expect our largest spring season to date, and we may hold tryouts in late February based on registration numbers. Venom tryouts were held to select our top teams. Players who did not receive a Venom invite will be placed on each team accordingly, based on skill, experience, and body of work with the program.
*Additional tryouts may be put into place for select age groups.
Teams
Teams will be placed in divisions based on the skill of the team as a whole.
