“Dr. Cialdini amazed our audience with his immense knowledge on the psychology of persuasion. His presentation style is relaxed, intense and ‘pleasantly confronting’. A brilliant mix! Over 350 managers could not get enough of Dr. Cialdini’s highly interesting lectures. After his last talk, he received a standing ovation, which is very rare in Holland. It was a sign of deep appreciation for his contribution to the success of the day.”
