Welcome to Mr. Duffey's website.  have been teaching math and coaching soccer at the high school level for 4 years.  Before teaching I had a twenty year career in Commercial banking. During my banking career, I learned how math is used in everyday life.  I teach Algebra 1, Advanced Algebra, and AMDM(Advanced Mathematical Decision Making). I have two sons in college and I take care of my two parents that all live here in Winder. Teaching math is a surprisingly rewarding career and I enjoy making a difference in the lives of students and players. I look forward to making all of my students successful, as well as achieving important tools they can use in life after high school.
