Our Mountain Math Guides

Our faculty is comprised of mathematicians with deep experience in mathematical research, camps, circles, and competitions. Led by Paul Zeitz, our faculty includes the most innovative thinkers in gifted mathematical education in the world for youth, including award-winning U.S. National Math Olympiad coaches, leading-edge mathematicians, multiple MacArthur Fellows, founders of leading math circles and gifted math camps, and math curriculum heads at the leading STEM schools in the nation. Andrew Chung, a grown-up math kid and parent of a math kid, will again lead a parents’ program focused on sharing best practices on raising mathematically-gifted children. One reason that we are excited about Math in the Mountains is because we have attracted amazing people to an amazing location.
