Hi, I'm Greg. I began teaching chemistry and biology at the secondary school level after graduation from The Citadel in 1974. Over the years I have taught various science courses including general science, physics, and organic chemistry. My students frequently come back after graduation to tell me they're convinced my teaching helped them to do well in these subjects on the college level, when many of their classmates were struggling. In 1991, I obtained a Master's in Chemistry from DePaul Unive
