Lindsey has been with Mathnasium since 2013. She holds a master's degree in Elementary Education from Grand Canyon University and always enjoyed math during her years of schooling.

When Lindsey is not teaching math, she can be found playing the piano, attempting Pinterest projects, or hiking the trails of Arizona with her husband. She was born and raised in Tucson and is therefore a U of A fan...sorry, folks!
