Sullivan Spivy

A San Francisco native, Coach Sullivan brings a unique perspective to Underdogs Basketball, shaped by both joy and adversity on his basketball journey.

Coach Sullivan’s love for basketball began as a baby and flourished through weekly 2-on-2 battles with his siblings in his family’s backyard. Throughout his playing career, he developed skills at all five positions, an experience that now forms the foundation of his coaching philosophy about versatility and understanding every role on the court. His freshman year under Coach Tom provided valuable insights into high-level basketball, though an injury three years ago the next summer shifted his path from player to mentor.

Coach Spivy made an impact as an assistant coach for a high school JV team that went undefeated in league play, with four players earning promotions to varsity by season’s end. When his own playing career was derailed by injury, he discovered that his need to stay connected to basketball could be fulfilled through coaching, and that the impact he could have on young players was even more meaningful than he had imagined.

His philosophy centers on using basketball as a vehicle for personal growth. He emphasizes having fun, building lifelong friendships, and developing life skills that extend far beyond the court. Wins and losses take a backseat to creating opportunities for young men to become the best versions of themselves while building an unbreakable brotherhood. His approach is rooted in respect and kindness for everyone, believing that this foundation allows players to flourish both individually and as a team.

At Underdogs Basketball, Coach Spivy is committed to showing young athletes that basketball can enhance every aspect of their lives, just as his own coaches demonstrated for him. His mission is simple: help players discover their potential, forge lasting bonds, and fall in love with a game that teaches lessons far beyond the hardwood.”
