Design Director, Sustainability

Tom is our design director for sustainability and a design principal in the Seattle studio. He actively leads the design direction of projects and our global efforts on low-carbon solutions. His current mass timber projects on the U.S. West Coast and Asia use our carbon-balancing methodology, targeting net-zero emitted carbon on day-one for structure, core and shell.  

His recent mass timber projects include the Orange County Sanitation District HQ and the recently completed CLTree kiosk at the University of Montana. He leads our mass timber working group; projects include a mass timber lab in Braunschweig, Germany, the CNL campus in Canada, and several tall buildings in British Columbia.

He's a frequent lecturer on design innovation, and the potential for long-term carbon sequestration of buildings at-scale, to reduce the climate impact of urbanization. Tom earned a master’s degree from the Harvard Graduate School of Design and is a recipient of over 25 design awards. He is the pro-bono design leader for an all-volunteer team for the U.S. Green Building Council's Children’s Center in Port-au-Prince, Haiti. The LEED Platinum and WELL Gold orphanage is positioned for triple net-zero performance when completed this year. He serves on the advisory board of the Biomimicry Center at Arizona State University.
