Ellianna Williams
Athletic Performance CoachVolleyball has never just been a sport for her—it’s been a lifelong commitment, a passion, and at times, a place to find strength when life felt anything but easy. From a young age, she poured everything she had into the game. Early mornings, late nights, countless hours in the gym—driven not just by talent, but by heart, discipline, and an unwavering love for volleyball. But her journey hasn’t been without hardship. Through personal tragedy and life’s toughest moments, the game became more than competition—it became resilience, purpose, and a way forward. That experience is what sets her apart. As a coach, she brings more than knowledge of the game. She brings understanding. She knows what it means to struggle, to push through, and to show up even when it’s hard. Her mission is to build athletes who are not only skilled on the court, but strong, confident, and grounded off of it. Her players aren’t just trained—they’re supported, challenged, and believed in. Because to her, volleyball isn’t just about winning. It’s about growth. It’s about grit. And it’s about becoming the kind of person who doesn’t quit—no matter what.Melissa Reterstorf
Athletic Performance CoachMelissa’s journey in athletics started as a volleyball player, where she learned firsthand the discipline, teamwork, and resilience the game demands. Those early experiences shaped not only her as an athlete, but also the coach she has become today. As a mom to a daughter who is actively involved in sports, Melissa’s passion has only grown. Watching her daughter compete and develop has deepened her love for youth athletics and strengthened her commitment to helping young athletes succeed both on and off the court. In addition to volleyball, Melissa is also a cheer coach, bringing energy, positivity, and a strong focus on teamwork and confidence into everything she does. Her background across multiple sports allows her to connect with athletes in a well-rounded way, emphasizing not just skill development, but attitude, effort, and belief in themselves. Melissa is passionate about building confident athletes. She focuses on fundamentals, game awareness, and mental toughness—while creating an environment where players feel supported, encouraged, and challenged to grow.Jason & Jen Lake
Athletic Performance CoachJason and Jen bring a unique dynamic to the program—not just as coaches, but as a team both on and off the court. As parents of athletes themselves, their journey into coaching began from the sidelines, supporting their own kids and quickly developing a deep appreciation for the game and the impact it has on young athletes. What started as cheering from the stands turned into something more. Through years of involvement in youth sports, they fell in love with the process—the growth, the discipline, the teamwork, and the confidence that sports can build. That passion naturally led them to step into coaching, where they could make a greater impact. Jason and Jen coach with heart. They understand the importance of creating a positive, encouraging environment while still challenging athletes to grow and push beyond their comfort zones. Their approach focuses on fundamentals, effort, and mindset, while always keeping the experience fun and meaningful. As parents, they know what it means to trust someone with your child’s development. As coaches, they take that responsibility seriously. For them, it’s about more than the game—it’s about building confident, hardworking athletes and creating an environment where every player feels supported, valued, and inspired to improve.
