Hello JPC,
I am in the kennesaw area, and I dont know of any vets that are knowledgeable about chameleons in your neck of the woods, but I take my animals to The Veterinary Clinic west in Marietta off Whitlock road. If you decide to not travel to the vet, I would suggest you choose a vet with caution, because some vets will say they can treat them, but really they have no experience. Dr.Brad Wilson is the vet at TVC West and is a major herp guru. He also breeds dart frogs on his own time, so exotic fauna is not foreign to him. Although Its a journey from you, I would really suggest taking your animals to him if you can.
