In my community service in Upington at the military base, I saw only one rep the whole year. That was none other than Terry Greyling. Terry knows so much about dental materials Google asks him for results. For a man with 50 years experience in an industry I don't know if he ever gets enough recognition. Be warned you need to book a long lunch to see Terry, as the information he channels doesn't stop before your assistant starts prying you with a crowbar from Terry's information download. I think if you would wake Terry in the middle of the night, he would still quote some literature and tell you what you need in your practice. But this is Terry someone you can feel the passion for dentistry radiate from his being. 

Terry you are a star and we salute you.
