Sienna Castillo Sienna Castillo 6'1" | MB/RS Redondo Union | 2027 State CA made the most of her showcase opportunity, using each drill to refine her timing and execution. She carried that work into six-on-six play, where she delivered a solo block against a back-row attack, one of her proudest moments. Her ability to stay locked in through both training and live play shows her readiness to translate skill work into game situations.

What stood out most to Sienna was how engaged and supportive the college coaches were, both on the court and during recruiting discussions. Their encouragement and insight into the June 15 timeline gave her confidence and clarity about what’s ahead. The experience helped her define what matters most in a college program, competitive energy, team connection, and coaches who are actively involved in player development. Her advice to future athletes: “Go in with a positive attitude and be ready to learn. Give it your all and be open to feedback. Most of all, have fun and enjoy the experience.” ~ Michelle Bamford @Coachable247
