"David and I were senior consultants at HRN, a public affairs agency that helped define corporate social responsibility long before most knew what that meant. David was a mentor, a friend and a partner on many a project. He's was the first true professional public relations expert I encountered and had the good fortune to learn from. Fifteen years and hundreds of PR friends, clients and colleagues hence, he still stands out as one of the best." Mark Nowlan is Marketing and Communications Leader at The Center for Wooden Boats
