Nelson Campbell

Founder & Board Chair, PlantPure Communities

On the heels of his successful effort as Executive Producer, Director and Co-Writer of the 2015 documentary film PlantPure Nation, and with the vision of leading a grassroots movement to promote the health benefits of plant-based nutrition, Nelson Campbell founded PlantPure Communities (PPC) in early 2016. The PlantPure Nation film (now on YouTube) examines the political and economic factors that suppress information about the benefits of plant-based nutrition, and makes connections to public policy, medical practice, food deserts, and farming. As the Chair of the Board at PPC, Nelson continues to drive the direction of the organization with his vision – including the PPC Oasis Program through which he is pioneering unique partnerships to bring food-as-medicine to underserved neighborhoods. Nelson also founded the socially conscious business, PlantPure, Inc., to develop the resources and capability necessary to launch the Healing America campaign, a grassroots strategy to empower people in local communities to help share the message of plant-based nutrition. This strategy utilizes a social action platform to support local initiatives that target different sectors of the community.
