Theory of Transformation

To help interrupt the destructive impact of the criminal justice system on black, brown, and marginalized communities and advance fairness, equity, and restoration in the administration of justice, sustained investment in those communities is required. Such an investment should focus on the recruitment, development, and empowerment of Credible Messengers to have transformative influence and impact in their communities and throughout the entire continuum of the justice system – including policing, court processes, community supervision, incarceration, and re-entry.


“Power at its best is love implementing the demands of justice, and justice at its best is power correcting everything that stands against love.”


― Martin Luther King Jr.

Clinton Lacey 
President & CEO
Credible Messenger Mentoring Movement – CM3

Clinton Lacey is the president and CEO of the Credible Messenger Mentoring Movement (CM3), a newly launched organization focusing on supporting Credible Messenger Mentors – community rooted natural leaders who have successfully navigated their own prior involvement in the justice system, who share similar life experiences with current justice-involved young people, and are poised to have transformative impact on an individual, family, community and systemic level – and maximizing their impact around the nation.

Prior to the recent launch of CM3, Lacey served as Director of the District of Columbia Department of Youth Rehabilitation Services (DYRS), Washington DC’s cabinet-level juvenile justice agency, where he was appointed by Washington, DC Mayor Muriel Bowser in 2015.

As a longstanding senior executive at the U.S. Department of Labor, Mr. Harrison provided leadership for management, operation, and direction for three USDOL agencies, contributing to advancing the mission of America’s employment and training programs, equal employment opportunity & affirmative action programs, and labor-management standards. He did a stint from 2012-2013, on executive loan from USDOL, with Office of the Mayor of New York City, working on the City’s $127 million Young Men’s Initiative. Lorenzo led the initiative’s Ban the Box effort, aimed at improving the employment chances of returning citizens by removing questions concerning an applicant’s arrest and conviction record from initial job applications.

Harrison spent seven years as the Administrator of the Office of Youth Services in DOL’s Employment Training Administration (ETA), where he helped lead and manage the nation’s $3 billion youth employment training system, serving hundreds of thousands of youth in the U.S. annually. The Youth Opportunity Grants initiative, a sophisticated systems development demonstration program focused on improving outcomes of 14 – to 21-year-old youth from 36 high poverty communities in the U.S., was a major focal point during Harrison’s tenure at ETA.

​He established the first Office of Youth Services at the Department of Labor in over twenty years. The Youth Opportunity program alone served 93,000 at-risk youth, including youngsters in the juvenile justice system, placing almost half of them in jobs, high school graduation, or college enrollment, and created a leadership institute that serviced 1,500 frontline youth workers in 36 communities nationwide.

​Regarded as one of the founding staff of the STRIVE program in East Harlem, New York, where he worked for over a decade before going to D.C., Harrison has considerable knowledge and experience leading and managing innovative, cutting edge non-profit organizations. He served as chief operating officer, responsible for leading this national, non-profit employment and training organization, then comprised of 31 sites in 11 cities. In the employment training arena, STRIVE is considered one of the nation’s premier community-based job training programs, credited with ‘putting a face’ on soft skills training and demonstrating the value of attitudinal development and long-term post-placement support of youth and young adults from low-income communities. STRIVE influenced various elements of the Workforce Investment Act of 1998.

​Lorenzo holds a master’s degree in Public Administration from New York University. He is a Kellogg Foundation National Fellow. Mr. Harrison and his wife, Glenda, live in Waldorf, Maryland, and are the proud parents of a son and daughter, and have five grandchildren.

Mosi Deterville-Makori
Chief Program Officer
Credible Messenger Mentoring Movement – CM3

Mosi Deterville-Makori is a social scientist committed to community-based participatory action research (CBPR) approaches to neutralize power disparities informing negative life outcomes among marginalized peoples. Under the tutelage of cultural workers and COINTELPRO survivors across the Black Belt, Mosi led initial project implementation and CBPR strategic planning to inform the Mississippi Roadmap to Healthy Living and GA Tools for Change.

After large-scale research demonstration experiences as a research analyst with MDRC in New York City, Mosi joined Students at the Center (SAC) shortly before synergizing leadership roles with SAC, Resurrection After Exoneration, and Innocence Project New Orleans. Spanning eight years, Mosi co-facilitated SAC’s Bard Early College English Courses across multiple New Orleans Public Schools, advancing post-conviction investigations, critical literacy- exchange, and shared-inquiry among secondary-post-secondary-post-baccalaureate (law) students, exonerated men and Angola prisoners – most of whom resided in neighborhoods bearing the highest incarceration rate in the world.

​Forming a constituency to critically assess, locate and liberate themselves within the carceral system, students centered discourse and action to circumvent power disparities maintained by the prison and academic-industrial complexes, as co-director, Mosi’s contributions refined SAC’s dialogic pedagogy and 21st Century Slavery and Human Trafficking course theme resulting in the release and exoneration of numerous persons serving life sentences and exoneration compensation policy reform in Louisiana. As a 2014 Nathan Cummings Foundation Fellow and 2015 Echoing Green Black Male Achievement Finalist, Mosi joined impacted communities and stakeholders nationally and abroad, co-organizing Andover Bread Loaf at Phillip Academy’s 4th International Education Conference in Port-au- Prince, Haiti. Facilitating cultural exchanges among youth descendants of the Haitian Revolution and New Orleans 1811 Slave Revolt, Mosi centered intergenerational Maroonage legacies of resistance and mutual aid in the wake of the 2010 Earthquake, Hurricane Katarina, and ensuing Disaster Capitalism. Mosi serves as a Sankofa Cultural Institute board member and principal of Star Institute for Conscious Organization.
