Meet the Team

Our Math Festival presenters are WONDERFUL! Each has had a full career as a classroom teacher and teacher-leader. Together we have hosted over 900 successful student and family Math Festivals. One of these presenters will work with you to thoroughly plan your event, and when your Math Festival date rolls around, your presenter will lead your event!
