“Coaching is amazing because you get to see total transformations. You see good athletes become great lacrosse players. You see good people become great teammates. You see timid girls become confident young women, and you have a hand in that. Hard work isn’t always popular, but once you commit to it wholeheartedly you realize that you are capable of anything. You can RIZE above anything if you have people who believe in you.”
