Diana Leafe Christian is an author, former editor of Communities magazine, and nationwide speaker and workshop presenter on starting new ecovillages, on sustainability, on building communities, and on governance by sociocracy. She lives in an off-grid homestead at Earthaven Ecovillage in the Blue Ridge Mountains of North Carolina, U.S. She has said that living in an intentional community "is the longest, most expensive, personal growth workshop you will ever take," though others are also associated with this quotation and it's unclear who originated it.
