William Trousdale is a certified professional planner, economist, and decision analyst whose work applies structured decision making, behavioral research, and negotiation science to strategic and local economic development, tourism, community and regional planning, and non-market valuation.
Since founding EcoPlan International in 1992, he has led over one hundred assignments for Indigenous communities, governments, and NGOs across the Americas, Asia, Africa, and Eastern Europe — including authoring UN-Habitat's resource guide and training series Strategic Planning for Local Economic Development, and working with Indigenous and non-Indigenous communities on developing economic development strategies. His projects have earned more than a dozen awards of excellence from CIP, PIBC, IAP2, and TTRA, most recently the 2025 IAP2 Core Values Award for the Squamish Nation Generational Plan. Some of his work has been translated into academic publications and guides.
