Mike Slatton is a 2nd generation American youth soccer coach since 1984, and the son of one of the nation's first female licensed youth soccer coaches (Anita Slatton, 1979). He's also a professional soccer scout, a player since 1977, and the father of three adult and teenage children who all play or have played the game. "My job as a youth soccer coach is to develop detail oriented problem solvers who can react quickly under pressure. This relates to life - not just soccer."
