Celebrating its 50th Anniversary this year, the Osseo Maple Grove Athletic Association (OMGAA) is a volunteer run organization.  OMGAA was formed in 1974 to provide baseball and softball opportunities within the Osseo and Maple Grove High School attendance areas.

We are dedicated to sponsoring a recreational program that offers various levels of play for both girls and boys, while promoting healthy sportsmanlike conduct.
