Jeff's passion for nonverbal communication was born in 1988 when he became a consultant in Total Quality Management (TQM) for eight years. This passion is the result of the convergence of two trends, his classical education and his formal training before he became an accomplished mime artist (Marcel Marceau's School techniques).

Jeff received a MS in Chemical Engineering from the National Polytechnic Institute of Grenoble, France and his MBA from Wharton, University of Pennsylvania.
