Josie Nelson


Director of Programs

JOSIE NELSON is an ethicist, an advocate, a certified health coach, and a lifetime student of holistic health. With degrees from both Georgetown University and the University of Chicago Divinity School, Josie planned a traditional academic career but a detour into management consulting changed everything. While her doctoral dissertation lay undone, Josie worked first with industrial engineering clients and later on business ethics initiatives. As a consultant for Fortune 500 firms, she learned many things about the health industry. Since 2002, she has dedicated herself to understanding the rise in childhood illness, especially autism and related disorders, from an historical, political, ethical, scientific and environmental health perspective. She has witnessed the profound impact of an approach to health that includes informed consent, access to real food, integrative medicine, and healing modalities not typically embraced by mainstream medicine. She once held elected office in the District of Columbia and lived to tell about it. She has been blessed with two healthy children, a fine sense of humor, and many wise teachers.
