Hello! I'm Mrs. Allison Duffer. I am so proud to be part of the Greenbrier community. It is a pleasure to serve the village of Arlington Heights and to be your child's teacher. I have been teaching for twenty four years....twenty of them here in District 25. I graduated from Illinois State University and received my masters degree in Curriculum and Instruction from St. Xavier University. I reside here in Arlington Heights with my husband, three sons, and schnauzer.
