In my career, I have taught mostly high school (Grades 9-12 following the American format. I have taught Earth Science, Environmental Science, Geography, Government, History, and Economics, however the last is my weakest. I have taught AP, IGCSE, and A-Level of each of these subjects, as well as a year of IB. I have used a proactive approach to instruction, trying to relate what the students learn to their lives. After 13 years overseas, my wife and I decided to raise our children here in the USA.
