Customer Testimonials
"I can personally attest that Charles is one of the heroes, perhaps an unsung one, behind the success of J. D. Power and Associates. In the mid-80's, John U. hired Charles to help him instill a new level of research discipline and to groom a team of skilled researchers. Charles helped take the company's research products and processes to a level where they became fully defensible, of high quality and integrity. The "message" of its research still generated plenty of slings and arrows over the years. But thanks to Charles' daily operational management and focus on quality, its armor was strong. Without Charles and the team of talented researchers he helped to shape, JDPA might have become only a brief footnote in the story of customer satisfaction."  March 28, 2011

“As Executive Vice President of both J.D. Power and Research Information Center, I had the pleasure of twice working with Charles. I found him to be highly intelligent, very creative and always motivated to do excellent work in whatever he was involved in. He worked very effectively with his staff, and they responded with consistent high quality work. If I were starting a business today, he would be the first person I would want to hire. Needless to say, I would recommend him unconditionally."
