Dr. Campbell worked at Moses Cone Hospital at the time he cared for me (2006-2007). My own doctor was stumped as to what my problem was and referred me to Dr. Campbell. I found him to be quite thorough, trying everything he could think of to diagnose the cause my illness. He also took into consideration my concerns and input. He always seemed prepared for my visits, having familiarized himself with test results and file notes before he saw me, not while with me. He discussed lab results with me. His staff also spoke very highly of him.
