Coach Dottie prides herself as being the volleyball coach ‘mom’ that everyone knows will be there for them and take care of them, as well as being the go-to person for any questions or concerns player’s parents may have.  She manages the team, records player statistics, and runs work teams and player responsibilities during tournaments.  She is IMPACT and CAP I certified.

He has also played volleyball for several seasons in various co-ed leagues in Loudoun County and often tries to play when the opportunity presents itself. “My philosophy concerning coaching is simple in that I focus on player development over winning. My goal is to ensure that your daughter enjoys her club experience while improving her skills, thereby benefiting the team. This is not to imply that winning is not important, but when we first focus on player and team development, winning is a by-product of that work”.

Her goal is to not only focus on making the girls better volleyball players but also better people beyond the confines of the court. She has a passion for volleyball, but more importantly, she has a passion for making sure the club volleyball experience is a positive one for each player.  She also has a passion for ensuring the players have an opportunity to learn from mistakes or moments when things didn't "go the way you expected or wanted."  She believes that attitude is everything.  Coach Charity strongly believes in being a good teammate on and off the court.

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 to practice and each other in those times are what matters. This environment creates space for mistakes to be viewed for what they genuinely are…learning opportunities that will make us a stronger, smarter team. The smart teams, having fun on the court, win in the areas that matter! Her sincere desire that these lessons cross the end lines of the court and that her players carry these ideals with them through life.
