About Marin Girls Softball

Marin Girls Softball League, with almost 1,000 registered players, is one of the largest youth softball leagues in California.

We're a volunteer-driven league for youth fast-pitch softball in Central and Southern Marin County.  We operate as a USA Softball district program - providing an educational-athletic program for any age-eligible child.  Any child can register and all registered kids play. 

Marin Girls Softball provides programs for 5 to 15-year-olds; from beginner to competitive travel ball.  Our goal is to help our players develop both life skills and a love of the game, through a positive coaching experience.

Marin Girls Softball Mission Statement

Marin Girls Softball aspires to be an outstanding educational-athletic organization, providing and expanding opportunities for softball players across Marin, from beginner (recreational) through to competitive travel-ball programs.

Marin Girls Softball aim is to offer a high-quality experience for every player.  A high-quality experience is one in which every player: 

  1. Is coached using the principles of positive coaching, developing confidence and self-esteem in every player
  2. Has fun at practices and games
  3. Feels like an essential part of the team
  4. Learns to promote sportsmanship, integrity, and teamwork 
  5. Learns “life lessons” that have value beyond the playing field
  6. Learns the skills, tactics, and strategies of the game, and improves as a player
  7. Has the opportunity to develop their game to their desired level: recreational, competitive travel-ball, and preparation for high school softball.

Marin Girls Softball recognizes that coaches, officials, and parents are the people who most directly make this all possible. It is our goal to provide every coach, official, and parent with a clear understanding of this mission, and the tools necessary to succeed.  

We are committed to creating a positive culture, in which coaches, officials, parents, administrators, and players, work together to achieve our mission.
