Geoffrey divides his time between consulting on strategy and transformation challenges with senior executives and on developing mental models to support his advisory practice. His newest book, Escape Velocity: Free Your Company’s Future from the Pull of the Past (Harper Collins 2011), is the result of his experience working with large enterprises in his former role as a Managing Director at TCG Advisors. His other bestselling books -- Crossing the Chasm, Inside the Tornado, The Gorilla Game, Living on the Fault Line, and Dealing with Darwin -- are required reading at leading business schools.

Geoffrey is a founder of both The Chasm Group and TCG Advisors. Earlier in his career, he was a principal and partner at Regis McKenna, Inc., a leading high-tech marketing strategy and communications company, and prior to that, he was a sales and marketing executive in the software industry. Geoffrey holds a bachelor's degree in literature from Stanford University and a doctorate in literature from the University of Washington.
