I guess we all have our favorite doctors. Have to disagree with your big four. I've done extensive research and can say without doubt that Feller is the best in the United States. I hardly see results from Cooley, Gabel, or SMG. Feller puts out results almost weekly. He's not afraid to put it out there which concerns me about other doctors who hardly put up their work. Konior is good and I put him in the same class with Dr Feller but I would like to see more patients put up by him.
