He was on President Ronald Reagan's U.S. Advisory Commission on Public Diplomacy.

In addition to Richard Edelman and Susman, DJE's board includes Ruth Edelman (deputy non-exec chairman); John Edelman, managing director at Edelman; Matthew Harrington, COO; Victor Malanga, CFO, and Steven Felsher, a former vice chairman of Grey Global Group.
