About Team Havlicek
A team built on belonging.
Team Havlicek was founded to lift up individuals with Williams syndrome and the families who love them. We believe every person deserves a stage to shine, a team to play with, and a community that celebrates them exactly as they are.
Through music programs, adaptive sports leagues, and community gatherings, we create spaces where confidence grows, friendships flourish, and every voice matters.
