Keep in mind that this board can be as toxic as any I have ever seen. There are very opinionated people and I tend to see the darkest of answers on here.
There are excellent coaches and clubs in SCV, just like everywhere else.
What works for one parent (should be the kid but often not) doesnt work for another. Kid is on a great team but gets less play time and suddenly the coach, team, club and the entire system is a dumpster fire.
Take your kid to tryouts, ultimately they should be the one that likes/dislikes the coach/team.
There is every level in town, flight 3/bronze to flight 1/gold.

Have your kid ask around at school. Good way to discover teams
Have fun, ignore the negativity around here.
