Dr. Wechsler is a family practice physician in Trenton. She is very respectful of non and delayed vaccinations when the parents are informed. Also Dr. Erinle in Ft. Oglethorpe. I believe he practices with Dr. Ho, and I *think* he's okay with delaying, but I'm not 100% sure. If you want to join the Mountain Mothers Birth Network (MMBN) yahoo group, there are pretty frequent discussions about pediatricians.
Oh, and welcome to the Chattanooga area :)
