Mark Fairfield, LCSW, BCD, Founder & Executive Director (Board Certified Diplomate in Clinical Social Work) received a Master of Science in Social Work from Columbia University in 1995. He was the former Clinical Director of Common Ground - The Westside HIV Community Center in Santa Monica, California. Mark has 20 years' experience in direct practice, program development and administration in community mental health, community organizing and public education. He also consults with other non-profit boards and management teams for strategic planning, leadership development and technical assistance. Mark's work during the AIDS crisis in the 1990s led him to a revelation about the role of interdependency in human health. He observed how social movements, with their strong emphasis on collaborative action and systems-thinking, keep people engaged in a common goal and embedded in dense networks of trust and reciprocity that actually make them healthy. So he dedicated his career to designing communication and organizing strategies that help people build and maintain interdependency, improving the conditions of communities and the relationships that constitute them. He continues to publish in books and journals on the subject of confronting individualism in social services and teaches/trains mental health providers and community organizers internationally.
