I know of a good one in Marathon but I know that is still quite a ways from you. Go back in and edit your title and say you are looking for a vet and you should get some more responses. go through this thread and you may find one in here. https://www.chameleonforums.com/area-area-country-vet-list-32880/index3.html
I go to South Kendall Animal Hospital. I don't know if it's near you but Dr. Faulkner sees my chams now and she seems great to me. She's treated several serious issues successfully for me.
where do you live??? I live in Lake Worth and that is considered South Florida. I have a vet I can recommend if you are near me. Is your chameleon sick?
