Book Description

Organizations that get diversity right reap tremendous benefits that ripple across the company culture and eventually lead to an indisputable impact on the bottom line. But robust, resilient diversity in the workplace thrives only when members of the majority group actively educate and challenge each other. Based on twenty years of pioneering workshops engaging white male leaders in transforming their own 4-days-change 500wmindsets, building leadership skills, and creating powerful partnerships at work and at home, Four Days to Change follows a group of men embarking in a life-changing process to broaden their view of the world and lead them into more authentic relationships across race, gender, and sexual orientation. Witness the kinds of conversations that have opened the eyes of thousands of white male leaders, freeing them to benefit from more inclusive, authentic partnerships in the workplace and at home.

Why did you write this book?

Why to change the world, of course!

Yes, I know. Sort of like boiling the ocean. Along with my partner, Bill Proudman, and all of WMFDP’s staff and consultants, we are on a mission. And while we have facilitated sessions for thousands of executives over the past twenty years, our reach is still minimal compared to the millions of leaders around the globe. So to have a sustainable impact on the world, we must extend our reach. And so, the book.

On a more personal level, I also feel the need to continue my own journey by writing as a way to further my authentic voice in diversity and inclusion work. The deep personal sharing and the 12 mindset shifts that occur in the book are examples of taking my voice forward. Four Days To Change is the book I always wanted to, from a passionate, humble, authoritative, vulnerable voice.

Whether with WMFDP or elsewhere, the book is also a powerful tool for facilitators. It demonstrates why and how our approach to the work is different than most, if not all other firms.

A meaningful book that will help white men redefine their role as key leaders for inclusion and equity in the workplace. Keith Nosbusch, CEO, Rockwell Automation

Four Days to Change shows white male leaders how to strengthen their organizations by having them understand and accept their responsibility toward improving equity.  It does so without shame or guilt and in a manner that encourages you and makes you proud to be a part of this work. Larry O’Dea, Chief of Police, Portland, Oregon

We know from our research that to develop more inclusive workplaces, we must fully engage and empower men to serve as agents of change. In Four Days of Change, Michael shares powerful insights that will help any organization transform into one that leverages and embraces differences, by equipping men to lead more inclusively. Deborah Gillis, President and CEO, Catalyst

We know we have to make race and gender visible for white men to fully engage men as allies.  But how?  In this valuable volume, Michael Welp compresses 20 years of facilitating that engagement into a book as deeply theoretical as it is handy and practical.  Quite a feat! Michael Kimmel, SUNY Distinguished Professor of Sociology and Gender Studies, Executive Director, Center for the Study of Men and Masculinities

More Testimonials

Four Days to Change challenged my thinking to recognize that as a white male leader in a high masculinity profession, I have a very real role in growing an environment of openness to the real – sometimes painful – realities for those of a different sexual orientation, the women, and people of color with who I live and work. Paul Schnell, Chief of Police, Maplewood, Minnesota

WMFDP has helped so many leaders rise to the opportunity to put their privilege to honorable use.  In Four Days to Change, Michael captures the essence of an experience that transforms diversity work from “someone else’s problem” into an inspiring opportunity to make the world a better place. Mark Burget, Executive Vice President, The Nature Conservancy

The W.K. Kellogg Foundation embraces differences and respects and nurtures people of all races, ethnicities and religions as a result of our longstanding relationship with WMFDP. Their body of work has provided the single most important factor in an organization’s success, which is the ability to create an authorizing environment for learning to take place.  An “authorizing environment” means that the place is completely safe at all levels, from boardrooms to bathrooms.  The change garnered in four days is palpable and its impact on lives and institutions is brought to life in “Four Days to Change”.   Congratulations on providing an effective tool for the field. La June Montgomery Tabron, President and CEO, W.K Kellogg Foundation

Four Days to Change can transform your mind, your heart and your life! Shattering the ‘Myth of Meritocracy’ this important book opens the eyes of white male leaders, like myself, and points us to a much more inclusive, authentic and value-creating world. Kevin Ashman, Senior Partner, CEO and Executive Development, Korn Ferry, Best-Selling Author, Leadership from the Inside Out and The Pause Principle



Through the work and introspection during the White Men’s Caucus, I’ve participated in one of the most impactful events in my 35 year career. Michael has captured the essence of the Caucus in his book, “Four Days To Change.” He has honed in on the essential element of this unique and enlightening experience for white men: learning to lean into our discomfort and to question our assumptions. This book will elicit a transformational experience for the reader that is essential in our increasingly diverse society. Paul J. Steffen, VP, Northwestern Mutual

Every so often, a book comes along that enables us to see the world differently, with the inspirational power to drive one to responsible action.  Four Days to Change is such a book.  As an attendee of the White Men’s Caucus, I can attest to the transformative insights Michael articulates in this easy to read book based upon his decades of experiential learning.  I found Four Days to Change enormously informative and life changing both on a personal and leadership level as we strive to support an increasingly diverse and inclusive workforce in full partnership.  A must read for any courageous leaders ready to begin their lifelong journey of enlightenment while viewing and understanding diversity and inclusion through their white male lens. Rick Gesing, Corporate Vice President, Worldwide Operations, Applied Materials Inc.

More Testimonials

This is one of the most profound books on culture I have ever read because it tackles the difficult problem of the culture within us that we don’t see.  By reviewing what happens in white men’s caucuses we learn the deep cultural differences that exist between races, genders, and sexual orientations, and see how these have worked their way into western business culture and our daily life.  This is a must read for those of us who are blind to the automatic privileges we enjoy. Edgar H. Schein, Professor Emeritus, MIT Sloan School of Management • Author of “Humble Inquiry and Humble Consulting”

As a white man reading this book I felt totally engaged and fully accounted for, caught up in the transformations that were taking place in front of me. To say this is “must read” is to understate its importance. A real tour de force! Thomas Coachman, COO, Kochman Mavrelis Associates, Inc., Co-Author, Corporate Tribalism, and Author, Black & White Styles in Conflict

Four Days to Change is, more than anything else, a book about possibility.  It, along with the work it represents, leaves us with hope that by honoring the human condition, and shining the light of consciousness on ourselves and others, we actually have the ability to transcend the wounds that divide us from others, and even from our own true nature.  Thank you for this book.  Thank you even more for your work. Howard J. Ross, Founder, Cook Ross, Inc., Author Everyday Bias and ReInventing Diversity

A courageous book about the critical journey and lessons that enable White Men to live and work authentically across differences. Judith H. Katz and Frederick A. Miller The Kaleel Jamison Consulting Group, Inc., Co-authors: Inclusion Breakthrough & Opening Doors to Teamwork and Collaboration
