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

– 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.

– An unwavering focus on the process and things necessary to ensure that you and your teammates strive for perfection mentally, emotionally, and physically.

– 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.
