Brian "Cas" Castelli
Junior Varsity Head Coach
Coach Brian “Cas” Castelli brings a lifetime of coaching experience and a deep love for the game to University High School. With sixteen years of high school baseball coaching across all three levels and more than forty years of total high school coaching experience, Cas is stepping into this new chapter with genuine excitement. He’s eager to invest in a new group of student-athletes and help them grow as players and young men.
Cas has spent three decades teaching in the Anaheim Union High School District, and along the way he has coached cross country, track, and even had brief stints with football, basketball, and soccer. Baseball has always been his true passion, and his dedication to the sport shows in everything he does. He also devoted years to coaching all four of his sons through their youth baseball journeys. One went on to play at MSU Billings, and another is currently competing at Cal Baptist. Cas and his wife of more than thirty years also have two daughters who round out their busy, sports-loving family.
One of the things that sets Cas apart is his appreciation for the mental side of baseball. He is already working with our players on strategies to handle both the highs and lows that come with competing. His goal is to help athletes build integrity, pride, and a genuine commitment to the game, knowing that the lessons learned on the field carry over into everyday life.
Cas considers it an honor and a privilege to coach your sons, and the Trojan community is fortunate to have him guiding the next generation of ballplayers.
