Sean is the principal of Heritage Green Consulting, a preservation consultancy working at the intersection of historic preservation and sustainability.

His work at Heritage Green is built on a career at the forefront of sustainability and decarbonization codes and policy, including his work at (ironically) New Buildings Institute. As an Associate Director, he was the subject matter expert on existing buildings for NBI’s work in energy codes, decarbonization policy and building performance standards.

He is a former chair of the Clark County Historic Preservation Commission and current co-chair of the Association for Preservation Codes Committee. He earned a Bachelor’s Degree in Architecture with a minor in Architectural History at the University of Oregon and a Master’s Degree in Historic Preservation at the University of Pennsylvania where he also earned a Certificate in Real Estate Development from a joint program between the Graduate School of Design and Wharton Business School.
