Jamie York is an internationally respected Waldorf math consultant, and author of Making Math Meaningful™ books. Jamie was born in Maine, went to public school in Connecticut, received two computer science degrees, and then began teaching math in 1985 at a boarding school in New Hampshire. In 1994, after spending two years in Nepal serving as a Peace Corps volunteer, Jamie’s search for meaningful education led him to Shining Mountain Waldorf School (in Boulder, Colorado), where he taught middle school and high school math for 21 years. As a self-proclaimed math missionary, Jamie traveled the world offering workshops for teachers to re-imagine mathematics and inspire their students. Making Math Meaningful™ books are the manifestation of his vision for a comprehensive mathematics curriculum that spans grades one through twelve. Jamie’s website, online math workshops, and books are resources for Waldorf teachers around the world. The award-winning Phi House is Jamie's first attempt at architectural design.

Karen van Vuuren, Jamie York's wife who believed in the Phi House project from the get-go, Carole Hanlein, long-time friend and former house-mate, who contributed her support and muscle-power on the day we erected the panels, Matthew Messner, fellow math educator who pitched in during the platform's construction, and our helpful neighbor Alan Polson who cheered us on from across the way. Thanks also to the various other construction helpers who played their part so well.
