Ryan Compher
JUNIOR VARSITY COACH
Coach Ryan discovered his passion for volleyball as a student at Trabuco Hills High School, where he played for three years. Since then, he’s built a decade of experience competing across indoor, beach, and grass formats. During his senior year, Ryan took a leap into coaching—and was instantly hooked. That first experience lit a fire that’s kept him on the court ever since.
Now entering his eighth season of coaching, Ryan has spent the past five years developing athletes at Saddleback Valley Volleyball Club. He brings energy, insight, and a genuine love for the game to every team he works with.
Currently, Ryan is pursuing his teaching credential and Master’s in English at Vanguard University, with plans to combine his two greatest passions: education and coaching. While he has his eyes set on becoming a high school English teacher and coach, he’s also exploring opportunities to play professional volleyball overseas.
Ryan is incredibly proud of every athlete he’s coached and is driven by the joy of helping others grow, both on and off the court. He can’t wait to keep doing what he loves—sharing the game and building up the next generation of players.
