Mark’s consulting practice is focused exclusively on serving CEOs,C-Suites, and boards of directors. Since 2015, he has also led research strategy for Deloitte’s Chief Executive Program.

His work over the years as a consultant and professor has inspired his writing for such publications as Harvard Business Review, MITSloan Management Review, and Journal of Management Consulting. An earlier book, “Guiding Growth: How Vision Keeps Companies on Course” (Harvard Business School Press, 2003), has been translated into multiple languages and is considered ‘the vision playbook for CEOs.’  His 2017 book, “Mean Men: The perversion of America’s self-made man, garnered media praise and three book awards for its incisive, no-holds-barred analysis of entrepreneurism’s dark side in the U.S.and beyond.

Mark currently serves on several nonprofit boards. Among them is Footsteps, a human rights organization that supports and affirms individuals and families who have left, or are contemplating leaving, insular ultra-Orthodox Jewish communities in their quest to lead self-determined lives.

He divides his time between New York City and The Berkshires of Western Massachusetts, where, for the past forty-five years, he has restored The Alderman Farm. As the third owner (deeded originally by King George III to the Alderman family), Mark feels history’s responsibility; he has brought the mountain-top property back to its original beauty and productivity. The Farm is currently a sanctuary for a large herd of retired work and war horses, representing near-extinct breeds.

Mark received his Ph.D. from the School ofManagement at the University of Massachusetts in Amherst and was an Erik Erikson Visiting Scholar-in-Residence in 2009 at the Austen Riggs Center.
