Dear Casey, Prof. Joseph Jankovic is a movement disorder specialist based in Houston since 1982 I believe and I was his first fellow from 1986 until 1987. He is well renowned among the movement disorder colleagues. They are performing surgeries for PD at Baylor College of Medicine, but I believe most of the surgeries are still pallidotomies. Best regards, Chris van der Linden, M.D. Movement Disorder Center St. Lucas Hospital Ghent Ghent BELGIUM
