Welcome to South Ontario AYSO Region 583!
Our Region has been operating as a Chartered Region since 1987. The majority of our players reside in the southern part of Ontario, California, however we have players from as far away as Fontana and beyond; even from Victorville.

Our primary purpose is to provide a Fair, Fun, and Safe place for our children to learn and grow into helpful, caring and successful adults. Soccer is the learning ground and a fun, positive environment is method.

Our park is located at

AYSO is an ALL volunteer organization, which means no one gets paid to volunteer their time. We volunteer for our youth to enjoy this wonderful game of soccer.
All our board members are volunteers. We do not have an office. Please try to reach us by text or after 5pm by phone. Thank you
