We are in South Carolina and were suprised that no one could help us in Charleston. After several visits we were referred to the Dermatology department at the University of North Carolina (not incredibly far from TN). We made one trip and they gave us so much information. The doctor had other doctors under him studying the condition and they are accessible the way a nurse would be in another office. They work through my ped here and I have not had to travel back. Anything I need, I call them and a doctor calls me back within 48 hours. I have been very impressed.
