Suk,
Google "volleyball clubs in atlanta" for a complete listing.

Wow. Atlanta. What fun. Y'all have a tournament called the Big South and it's HUGE in Atlanta. This year it's in the beginning of April. Okay. You need to look under usavolleyball.org and aausports.org to find a club in your area. Vball is pretty big there (hello, Big South?) so finding a club shouldn't be hard. I love the Atlanta clubs so much, here you go:

Everything you need to know about clubs should be right there. Tryouts should be going on RIGHT NOW, so get to researching. Ask any HS or MS coach or the parents of players which club may be right for you.

GOOD LUCK! Hope to see you at the Big South!
