Thomas Zweifel

Thomas David Zweifel is a Swiss-American university professor known for his theories Strategy in Action, the Global Leader Pyramid, and the Matterhorn of Masterful Listening.

Career
From 1985 to 1997, Zweifel worked for the non-governmental organization The Hunger Project. As its Director of Global Operations (from 1992 to 1997), he lived in various European countries as well as in Japan, India, and the United States. He was responsible for the profitability of 27 Global Affiliates but did not have the legal power to manage them through command-and-control. So he learned the skill of coaching in action. Zweifel became co-founder and CEO of Swiss Consulting Group, a management consulting firm, which he sold in 2013. Since then, he has worked independently as a management consultant for strategy and performance.

Academics
In 1996, Zweifel earned a master's degree from the School of International and Public Affairs at Columbia University. In 2001, he earned a PhD in International Political Economy from New York University with a thesis on the democratic deficiencies of the European Union, particularly in the regulation of corporate mergers. Zweifel has also taught as an adjunct professor at Columbia University since 2001, and as an adjunct lecturer at the University of St. Gallen since 2004.
