In 1993, Dr. Katz co-founded the Mentors in Violence Prevention (MVP) program at Northeastern University’s Centre for the Study of Sport in Society. The mixed-gender, multiracial MVP program is one of the longest-running and most widely influential sexual assault and relationship abuse prevention programs in both secondary and higher education. It was the first large-scale program of its kind in university and professional sports culture in North America, as well as in all branches of the U.S. military. 

Among its many accomplishments, MVP introduced the “bystander” approach to the gender violence prevention field; Katz is a key architect of this now broadly popular educational strategy. Since 1990, Katz has delivered thousands of keynote addresses and conducted trainings in all 50 US states, 8 Canadian provinces, and every continent except Antarctica. 

Katz is the creator of the award-winning and widely used Tough Guise educational documentary series. His other films include The Bystander Moment: Transforming Rape Culture at Its Roots, and The Man Card: White Male Identity Politics from Nixon to Trump. He is the author of two critically acclaimed books, including the classic The Macho Paradox: Why Some Men Hurt Women and How All Men Can Help. His next book is entitled Every Man: Why Violence Against Women is a Men’s Issue, and How You Can Make a Difference. It is scheduled for publication early next year by Penguin Random House UK.
