There's a considerable projection in any of the previous posts regarding why there aren't more / more successful female coaches, and using personal experience is anecdotal. However, doing so in my daughter's case would show that the only female head coach she had in club soccer was a two-time national champ and the coach of the D1 national champions in her first year of college play is a woman.
Also, in terms of team culture, the club coach I mentioned above is exceptional. I still remember the first time I saw her coach. Her demeanor on the sideline was calm, her communication was always constructive, and her team played skilled soccer. Over time, I saw her responses to winning and losing, and it was exactly the behavior I wanted my daughter to model. A few years later, my daughter joined a team she coached, and I observed the same positive behavior in training and in communicating with parents. If we could do it over again and only select one coach, she would be the one.
I don't claim to know why we don't have more / more successful female coaches at the club level. It may have to do with the fact that many of the more successful ones get better opportunities. I know that Quakes/Bay Area had two - Erin Ridley, who is now with the boys' side of the Earthquakes, and Natalia Astrain, who is now coaching the USWNT U17s. Also, Margueritte Aozasa was coaching at MVLA. My take is we need more women coaches at the club level coaching girls - and boys if they are so inclined.
