During his time overseas, he has led student excursions to Australia, New Zealand, Indonesia, Malaysia, Nepal, and Cambodia. He began his career as a faculty intern at Culver Academies in Indiana, and has also worked at Culver’s Summer School as a counselor for the Black Horse Troop.

Lewis holds an A.B. in English from Georgetown University, where he was a Lannan Fellow, and he earned an Ed.M. in Teaching and Learning from the Harvard Graduate School of Education, and an M.A. in Private School Leadership from the Klingenstein Program at Teachers College, Columbia University.
