karen & jim, My name is Jeff Konin. I also am a physical therapist. I teach in a PTA program at Delaware Tech. While my previous experiences have found me specializing in orthopaedics, I have taken the challenge of becoming a full-time instructor with the hopes of graduating competent PTA's to our field and the opportunity for me to teach and therefore be forced to learn about a lot of other topics. I don't have much experience with PD, but I am always lookign for info, especially if you are also in PT education. Jeff Konin
