Sol Erdman founded the Center for Collaborative Democracy to develop innovative tools for reaching constructive agreements on long-festering political controversies. Erdman's expertise on resolving ideological conflict emerged at midlife, when he attended the Program on Negotiation at Harvard Law school and did cutting edge research with two of the program’s founders. Erdman’s articles on how to bridge seemingly irreconcilable differences have appeared in Barrons, the Boston Globe, the Chicago Tribune, the National Civic Review, State Government News, Roll Call and the Los Angeles Times.
