A good chunk of Jon Walton’s higher education was devoted to environmental and natural resources policy and science, and he helped start a Pacific Northwest conservation group bringing together disparate stakeholders on win-win conservation projects. Jon spent his first five years after college as a wilderness skills instructor working with juvenile delinquent youth. Later odd jobs included FEMA-funded mental health work for victims of natural disasters, and providing leadership training to executives of major corporations. A member of his state bar since 1992, he always intended to put his legal training toward service in the public sector, and started by working as legislative staff, and then a state agency lobbyist, at his state legislature. Someone obviously having difficulty figuring out exactly what to do when he grows up, Jon came to government procurement in 1997, working in state agencies, and has felt fortunate to handle a large variety of procurements and contracting situations. Jon strives to be a champion for procurement training and certification, has a graduate Certificate in Public Management, is the author of the Public Procurement Guide for Elected Government Official, was Chair of the NIGP Legislative & Position Committee, was the 2015-16 Buyer of the Year, and continues to be heavily involved in NIGP initiatives, task forces and global best practices. Jon is currently recently completed several terms on the NIGP Governing Board, and is an NIGP Instructor and part of the Radio NIGP team.
