*NEIL D. SAMUELS's mission is helping leaders flourish by re-discovering their strengths, clarifying their commitments, and fundamentally changing their conversations with themselves, their teams, and their organizations. He believes that conversations characterized by depth and intensity lead to successful, lasting change. His clients value his integrity, passion, and ability to magnify their strengths.

Neil received a bachelor’s degree in geology from Ohio University and a master’s degree in geology from the University of Cincinnati, after which he worked in energy exploration for BP in the U.S. and West Africa. While working for BP, he made a career shift to coaching and consulting, earning a masters degree in organization development from Pepperdine University. Neil has served as an examiner for the Texas Quality Award and was certified as a Total Quality Manager. In addition, he is certified in and applies a number of instruments in his coaching including the VIA Survey of Strengths.

Neil devoted 27 years of his career to Amoco/BP, 10 as a geologist and 17 as an internal consultant. He co-developed a cost-effective, web-based process to be used for 360° feedback throughout BP. He also developed, applied, and trained others in an appreciative-inquiry approach to feedback for use in leadership development. His extensive work with senior leaders and their teams helped create robust strategies with true alignment throughout their organizations. In his final internal role, Neil worked in London for four years as manager of organization development for Europe, leading a team of consultants serving 30,000 employees in 13 countries. During that time, Neil supported senior leaders in every business segment.

Having worked on six continents, he’s presented and published in the management, education, and organization development fields in the U.S. and U.K.; many of these contributions concern the application of appreciative inquiry in both business and education. Neil also served as adjunct faculty at Pepperdine University’s Graziadio School of Business and Management.

Neil resides in the Chicago area with his wife and teenage son. Always looking for a bridge game, Neil also plays tennis and enjoys bicycling on the prairie paths near his home.
