This is who
we are.


MMG is a research and change management firm that centers the principles of racial justice and social justice in all that we do.

We help people in the private and public sector transform their communities and global societies. MMG partners with organizations that range in size from 20 employees to 6,000. We hold more than 15 years of experience developing and implementing research and change management strategies for equity, justice, and belonging in tech companies, foundations, healthcare groups, progressive organizations, and academic institutions. We help organizations and companies create actionable and impactful data-informed frameworks for transformation. Our global network of researchers, strategists, and facilitators has implemented some of the largest change management actions in the world.


In some of the largest change management firms in the world, firms tasked with driving the socialization of COVID-19 vaccine campaigns, cutting delivery times in half for lifesaving medicines, building businesses that change the fabric of our global societies, actually creating internal culture that aligns with the values that these companies present to their clients proves to be an enduring failure. At MMG, we don’t just engage in change management work that helps our clients build, create, and dismantle. We live by our principles and continuously innovate in creating a radical, trauma-informed, and harm-reductive culture that builds our community up as opposed to tearing them down in the name of innovation.

Here are some of the benefits we offer to part-time and full-time team members:

  • Full benefits (health, eye, vision)
  • 1 30-day paid sabbatical/year
  • Free therapy (with on-staff therapist)
  • Director of Healing + Repair who supports our team with facing conflict, confronting harm, and seeking repair
  • Unlimited PTO (with a 6-week mandatory minimum)

At MMG, innovation doesn’t begin with our clients. It begins with us. We can only be enterprising, creative, strategic, and brave as we demonstrate ourselves when are clients are not in the room.  That’s true innovation. Welcome to MMG.

Who would we be without the oppression? What could we do? Where could we go?

Our vision is creating a world that is centered in the principles of accountability and repair, justice and harm reduction, courage and imagination. We imagine communities at work and beyond that are led by a desire to honor and respect each other’s dignity, wellbeing, capacity, and humanity. This is our vision.

Acknowledge Power, Name Privilege
We agree to struggle against racism, sizeism, transphobia, classism, sexism, ableism, and the ways we internalize myths and misinformation about our own identities and the identities of other people.

Stop Harm, Seek Repair
We know that no space can be completely “safe” and we agree to work together towards harm reduction, centering those most affected by injustice in the community even if it means centering ourselves.

Normalize Vulnerability, Embrace Discomfort  
We agree to sit with the discomfort that comes with confronting the complexities of harm, repair, identity, and accountability. We agree to try our best not to shame ourselves for the vulnerability that this kind of work requires.

Build Coalitions, Build Community
We agree to value the viewpoints of other people that do not challenge or conflict with our right to exist nor with the right of others to exist. We agree to build communities that are founded in our shared liberation.

Do the Work Together, Never Alone
We agree to work together; to build change management and research processes that offer everyone an opportunity to contribute, to create, to act. We know we don’t have all the answers. We do this work in community. Our clients are our collaborators. They have just as much to teach us as have to teach them.
