I’m excited to continue serving as Youth Director for the Shore Program and coaching our 2034/2035 and 2028 teams. This role gives me the incredible opportunity to work closely with many of our Shore players throughout the year. As both an educator and a coach, my passion lies in empowering and developing students and athletes to become the best versions of themselves.
Mad Dog’s strong commitment to player development fosters dedication, resilience, and a strong work ethic—qualities that transcend athletics and positively shape our players’ lives. The sense of community among coaches, players, and parents truly makes this program feel like a family.
I’m grateful to be part of this supportive environment, where I can make a meaningful impact and continue to grow as a coach.
