Our Team

Dr. Jeffrey A. Zink


A retired career lieutenant colonel in the United States Air Force, Dr. Jeffrey Zink works as a highly acclaimed facilitator and motivational speaker on ethics and leadership enrichment. Jeffrey gained his theoretical knowledge of ethics and philosophy through undergraduate study at the University of Pittsburgh, master’s work at the University of Southern California, and doctoral study at Oxford University, England, where he earned his doctorate in moral philosophy in just under 2½ years for his research into the morality of strategic nuclear deterrence. He continued to refine that knowledge through thousands of hours in the classroom teaching professional applied ethics, practical reasoning, and symbolic logic, and through three additional years as a student in various military professional development institutions.

Jeffrey’s practical experience began with over 2,000 flying hours as a navigator and bombardier in B-52 strategic bombers during the height of the Cold War. His missions included Operation Bright Star, a historic 32-hour nonstop, round-trip flight from North Dakota to a demonstration bombing run near Cairo, Egypt, a flight for which he was awarded the U.S. Air Force Air Medal.

Jeffrey also gained managerial experience as chief of the newly formed Treaty Compliance Division at Fairchild Air Force Base near Spokane, Washington, where he took charge of preparations for Soviet, then Russian, inspection visits dictated by the START and Nuclear Threshold Test Ban treaties, as well as various other operations, including food relief flights to western Russia in 1991. Executive experience came through his selection as squadron leader at the USAF Air Command and Staff College, as well as in his position as Director of Operations for the Department of Philosophy and Fine Arts at the U.S. Air Force Academy, from which he retired in 1997.

Since 1994, Jeffrey has been sharing his knowledge on ethics and leadership enrichment with thousands of people in a wide range of audiences throughout the United States and Canada, as a speaker and executive life coach. His client list includes  Pikes Peak National Bank, KB Home, Southwestern Energy, Nestlé Waters North America, the Simmons Mattress Company, Agilent Technologies Inc., and components of the U.S. Federal Government, including the Department of Defense and the Office of Personnel Management. He is the author of Hammer-Proof: A Practical Guide to Values-Based LeadershipChoices: Using Values Every Day, and From I to WE: The Round Table Journey. In addition, he is a partner in Zink Executive Wellness, helping to create cultures in which people are committed to each other and the values of their organization.
