Mark Lipton is graduate professor of management at The New School in New York City. For over forty years, he has been a trusted adviser to a diverse client base, including founders of transformative start-ups, global Fortune 500 companies, think tanks, and some of the world’s largest NGOs.

Mark’s latest book, Mean Men, synthesizes decades of psychological research to expose what really drives this subset of America’s leaders. As surprising as it is alarming, the book reveals dark truths about a psychological disorder that rules many of our boardrooms, and challenges the status quo with a more effective humanistic approach to leadership.
