Dr. Wallace and his entire staff made my experience absolutely wonderful. They are kind and gentle and made me feel so comfortable while I was there. I traveled for 2 hours (each way) to see him several times as I heard he was the best, and I have to say that I have no doubt that he is. The drive was well worth it.
