Paul M. Mastrangelo, Ph.D. is an internationally recognized expert in employee-centric workplace change.
Over the past 25 years Paul has applied his organizational psychology background to conduct culture and engagement assessments to spur behavior change in organizations such as Advanced Instruments, Air Canada, Apple, Bozzuto, Cisco Systems, GLG, Goodyear, Hewlett-Packard, HSBC, Johnson & Johnson, Northwest Healthcare Properties REIT, Salt River Project, Raytheon, SABIC, Standex, the United Nations, Vans, Viacom, Vontier, and Wittington Investments. Paul has worked with CEOs, CHROs, C-suite teams, managers, and union members via results presentations, team building, facilitated group sessions, and one-on-one coaching meetings. His work has spanned 14 countries, literally taking him all over the world.
Paul works at First Domino Consulting, a firm he founded to teach business leaders how to design the human side of workplace behavior change. His recent innovations include the Infectious Change Design program, which combines leadership development with change coaching and organizational consulting, and the Culture Assessment Matrix, which advances the employee survey to a more precise OD transformation technique. Previously, he created the Peer Nominated Team as a change intervention and the Progress Pulse as a reoccurring leadership nudge.
His prior employer had been bought, sold, merged, and renamed more times than he cares to remember – from a private US company of 30 employees at Genesee, then acquired by CEB (2,000+ employees globally) and then Gartner (10,000+ employees globally), before being divested and merged with a CV-backed NYC startup called CultureIQ (100 US and British employees). Before that, Paul trained many leaders and professors in people analytics as Associate Professor at the University of Baltimore (plus Lecturer at Rochester Institute of Technology, Saint John Fisher University, and University of Rhode Island), teaching technical courses in statistics, research methods, and personnel assessment.
Paul is a thought leader in the OD field, having authored a book with Ingwer Borg plus 10 chapters and 23 journal publications (with co-authors) for both science and practice. He is a regular presenter at the annual conference of the Society for Industrial and Organizational Psychology, where he has presented 39 times since 1995. Paul received his Ph.D. in Organizational Psychology from Ohio University in 1993 and his BA in Psychology from the University of Rhode Island in 1989, where he was inducted into the Phi Beta Kappa Honor Society.
On a personal note Paul is a native of Rhode Island (USA) who spends time playing rock and jazz on piano, improving his pace as a 5-10k runner, developing his pandemic hobby of long-distance longboarding, and enjoying quality beverages with his wonderful wife while keeping up with four adult children. He maintains a professional online presence on LinkedIn.
