John is a graduate of the American College of the Building Arts, where he studied timber framing, architectural history, preservation, drafting, and the building trades. That education is complemented by experience working on timber framing and construction projects across the United States and abroad, exposing him to a wide range of building traditions, materials, and approaches to craft.
