My goal is to ensure that your daughter enjoys her club experience while improving her skills, thereby benefiting the team as a whole. This is not to imply that winning is not important, but when we first focus on player and team development, the winning is a by-product of that work”.

Asst. Coach, Jodie White 

Coach Jodie is excited to be the Assistant Coach for the DYS U14 club volleyball team. Her love of volleyball began on the sidelines, where she was always cheering for her daughters. Three years ago, during the LYV season, she moved from the sidelines to the bench, and she hasn't stopped coaching since!  She is IMPACT, and Safesport certified. Coach Jodie’s favorite thing about coaching is creating a supportive, nurturing team environment. Every member of the team from players, coaches, and parents understand that they are an integral part of that dynamic and what is expected of them. First, we will have integrity in all of our relationships. We will be kind, supportive, and fierce advocates of each other on and off the court. Secondly, the attitude that we bring to practice, and matches are of the utmost importance. We will have good days and bad days, but how we approach practice and each other in those times are what matters. This environment creates space for mistakes to be viewed for what they truly are…learning opportunities that will make us a stronger, smarter team. The smart teams, having fun on the court are the ones that win in the areas that matter! It is her sincere desire that these lessons cross the end lines of the court and that her players carry these ideals with them through life.
