You should consider a few things when joining. Start with where you live. For example, if you're in Nassau, Liberty is prob your best choice. If you live in Suffolk, Top Guns or YJ. There are others, of course, too. Go to a few tryouts and then you can decide based on what teams she makes, the cost for the program and the tournaments they attended (and maybe how well they did or didn't do), the prior summer.

Good luck! My daughter plays in college and is finished with her summer lacrosse playing days. I miss them!
