The American Youth Soccer Organization (AYSO) provides youth soccer programs nationwide. The soccer programs follow six principles: Everyone Plays, Balanced Teams, Open Registration, Positive Coaching, Good Sportsmanship and Player Development.
The Mountain View and Los Altos branch of AYSO, Region 45, was first developed in 1974. It is a non-profit, volunteer-run program that serves close to 2,000 children, ages four-and-a-half to 18.
