Since they had CAO - south of perimeter I can also count
ACE of Atlanta
GA Heat
Nitro - which is now Total Athlete
??? There a bunch
If you start at the center of Atlanta and drive out 1 hour you'll hit at least 50 gyms. Go to hours you get 75 or so and 3 hours pretty much clears the state all around with about 100 Allstar gyms.
Biggest names of note in the state or level 5 teams that I know of - Stingrays, GA Allstars, ACE, A-Towne Allstars (ATA), Jayhawks, Twisters, ProCheer, Trinity, C4 Longhorns.....
Again, lots of teams but only 9 that I know of with level 5 programs. But I might be missing some.
