Our Mission

To help girls develop confidence, teamwork, and resilience in a fun, safe and family-oriented softball environment.

Our Core Values

Seriously Fun: We believe that enjoyment is the foundation of learning and growth. Every practice, game, and team activity should be an opportunity for our players to have fun. 

Growth Mindset: We focus on learning and improvement rather than just winning. Success is measured by effort, learning, and personal development which helps build confidence and resilience.

Teamwork: We foster a spirit of cooperation and encourage everyone to show up for their team – teaching girls the value of working together towards common goals. 

Inclusivity: We welcome girls of all skill levels, backgrounds, and abilities. Everyone who deserves a chance to play, learn and grow, provided they are respectful and attend practice.

Sportsmanship: We teach and model good sportsmanship, emphasizing respect for teammates, opponents, coaches, and officials.

Safety: The physical and emotional well-being of our players is paramount. We maintain a safe environment and teach proper techniques to prevent injuries.

"Softball is the main thing I remember from growing up, so I would pretty much equate my MVGS experience with my childhood experience. I was a shy kid, so having teammates and a sport where I excelled did a lot for my self-confidence and social skills. It's been 20 years since I first joined MVGS (whoa) and some of my best friends today are former teammates. Being part of a group that works toward a shared goal is an amazing bonding experience, and my friends and I still reminisce about our early softball days!

I would encourage every young kid to join MVGS. Being part of a team has so much value, but beyond that, softball is special. It's a technical game with so many facets. There's room for a huge range of skills from mental strategy to physical coordination. It really is a game of specialties, which means there are so many opportunities to fit in."

Welcome Mill Valley softball players and families to the 2026 registration page!  It is our mission to teach the fundamentals of softball, to learn what it is to be a great teammate and to have a fantastic time.  We encourage as many parents to get involved with MVS, whether it be coaching, events, finance, assistant coaching, groundskeeping or snack table.  You and your kids will get more out of it than you can imagine!

This registration session will allow you to complete contact information, sign up for participation or sponsorships and submit payment. To complete registration through our secure site, please have your credit card available.

For all girls, ages pre K - 15 years

• Games are scheduled for all Marin County districts by Marin Girls Softball.  
• Practices start the week of February 22, 2026
• Regular Season lasts from mid March - third week of May.
• The last week of May is for playoffs. First weekend in June is for All Stars.
• All teams will make playoffs in either the GOLD or SILVER bracket
• All games are in Marin County (10U and up games will be played as far north as Novato)
• All home games are at Hauke Park or Tam Valley School
• Practices will be held at Tam Valley School and Hauke Park 

We try to grant friend requests but do not guarantee it. The intent is for each team to have a 10 player roster with three coaches. The intent is to provide the maximum number of repetitions to each player.  

Coaches pick practice days/times so we do not know the practice days until the head coach is confirmed and it works for their schedule. Typically, practices are held 4-530 (as an outdoor sport, lighting and weather conditions obviously can impact availability)

- Recent news in the Marin I-J

- Right now in Mill Valley, girls are not provided the same opportunity for participation in softball, in quality or scope, as the opportunities provided to boys who play baseball.

- Hauke Park, home of Mill Valley Softball, has subpar dugouts with no roof or equipment storage, no pitching warm up areas, no outfield fence, no concessions, no scoreboard, no place to store equipment on-site, while the boys have all these things. Mill Valley Little League has 6 fields, 6 equipment storage areas, 6 pitcher warm-up areas, 4 fields with enclosed dugouts, 3 score boards, 3 fields with outfield fences, 2 snack shacks, 2 fields with livestream video capabilities

- This is an argument about fair play, equality, and opportunities in the community. 

- No other community in Marin bans field use on weekends for local community sports organizations and Mill Valley should not either. Removal of the restriction on Sunday use would allow softball to hold additional and rain-out games on Sundays and provide opportunities for clinics to make our program more competitive.  Field use would be governed by Mill Valley Parks and Rec staff to balance neighborhood interests with field use schedules rather than the Bay Front Master Plan.

- We are excited about the opportunities to improve the Mill Valley softball facilities and program.
