John McLean served as a spokesman for the sunflower industry for almost 40 years. He worked in the grain industry since 1973, with 32 of those years at Cargill. His primary responsibility was commercial seed origination. He considers the development of NuSun oil as the highlight of his time spent on the NSA board of directors. The foresight of the organizers of NSA to have a board of directors made up of both producers and industry personnel was something McLean credits as the foundation for success of the organization and the crop.
