Scott has over 30 years of experience tackling waste management issues in the public, private, and nonprofit sectors. He is a founding Board Member and four-time past-President of the North American Hazardous Materials Management Association (NAHMMA), and a founding Board Member of the Global Product Stewardship Council.

As PSI’s CEO, he developed the widely acclaimed facilitation process that the organization uses for stakeholder engagement and consensus-building—a process that resulted in the nation’s first industry-run, government-mandated paint stewardship program. Scott holds a master’s degree in Environmental Policy and Dispute Resolution from the Massachusetts Institute of Technology, and a bachelor’s degree in Geology and Environmental Studies from the University of Pennsylvania. He loves craft beer, frisbee, photography, and playing the harmonica any chance he can get.
