Program Philosophy
Family– Through unconditional love we will build a trust that will allow for individuals and the team to achieve remarkable things both on and off the court, while cultivating relationships that will last a lifetime
Attitude– A positive attitude combined with a disciplined team-first mentality will ultimately lead to positive results. The right attitude will lead to vulnerability, and result in personal and team growth.
Toughness– An unwavering focus on the process and things necessary to ensure that you and your teammates strive for perfection mentally, emotionally, and physically.
Finish– Complete a task from start to finish, with focused attention to detail and full effort. Follow through both on and off the court is the expectation. Whether it is chasing down a loose ball in practice or thoroughly completing all school assignments, finishing is critically important to sustainable success.
