Dear MDSA Families,

As the Referee Administrator team, we want to welcome you to another fun and exciting year of soccer.  We know that no matter what skill level your child has in soccer, MDSA will work very hard to provide a fun, family friendly place for them to learn about soccer and themselves.

AYSO's Mission is to provide world class youth soccer programs that enrich children’s lives. As an ALL VOLUNTEER league, the key to our success is the willingness of ALL parents of children who participate to be actively involved in creating a successful environment for children and families.
