After studying Communication at the University of Arizona, Peter began his career as a rock climbing and whitewater instructor for Outward Bound in the Northwoods of Maine. Peter became Outward Bound’s Operations Manager and later pursued a Master’s degree in Resource Management from Antioch University. Following Antioch, Peter became the Pollution Prevention Manager for the state of Maine. At Maine’s Department of Environmental Protection Peter developed sustainability programs for dozens of business sectors including starting one of the nation’s first green hotel programs (over 200 businesses in Maine participating). The success of the model used for Maine’s hotels prompted the Sustainability Manager from Hannaford, New England’s largest grocery chain to inquire if the methodology could work for grocery stores. After a successful implementation for Hannaford, Peter joined Manomet, a sustainability non-profit and founded the Grocery Stewardship Certification (GSC) Program in 2012. The GSC became a nationwide sustainability platform for the grocery sector with more than 1,000 grocery stores from 15 chains (including Ahold Delhaize, Whole Foods, Albertsons, Sprouts, HEB, Hy-Vee, Brookshire Brothers, Shop and Save) applying store-level sustainability improvements that reduce operating costs. Peter has facilitated the process of establishing sustainability strategies for companies such as L.L. Bean, Bowdoin College, Sunday River, and Easter Funding. Peter is ISO 14001 Lead Auditor certified, Commercial Energy Auditor trained, Building Operator Certified, and Hazardous Waste Operations certified. Peter teaches as adjunct faculty for Antioch University, Tufts University, and the University of Maine.
