A World Without Violence

Cure Violence is guided by clear understandings that violence is a health issue, that individuals and communities can change for the better, that community partners and strategic partnerships are keys to success, and that rigorous, scientific, professional ways of working are essential for effectiveness.

Our Mission: To reduce violence globally using disease control and behavior change methods.

Cure Violence Vision

Violence behaves like a contagious problem. It is transmitted through exposure, acquired through contagious brain mechanisms and social processes, and can be effectively treated and prevented using health methods. To date, the health sector and health professionals have been highly underutilized for the prevention, treatment, and control of violence. Now is the time to mobilize our nation’s healthcare and public health systems and methods to work with communities and other sectors to stop this epidemic.

Cure Violence History

Cure Violence was founded by Gary Slutkin, M.D., former head of the World Health Organization’s (WHO) Intervention Development Unit. Cure Violence launched in West Garfield Park, one of the most violent communities in Chicago, and was quick to produce results, reducing shootings by 67% in its first year. From 2000-2008, Cure Violence focused its activities in the United States, quickly expanding to Baltimore, New York, New Orleans, Oakland, Loiza, Puerto Rico and other sites. In 2008, Cure Violence began its first international adaptation and replication of the methodology in Basra and Sadr City, Iraq.  Since then, international programs have been added in Canada (Halifax and Alberta), Colombia (Cali), El Salvador (San Salvador and San Pedro Mazawal), Honduras (San Pedro Sula), Jamaica (St. Catherine North and St. James), Kenya (Nairobi and Rift valley), Mexico (Ciudad Juarez and Chihuahua City), South Africa (Hanover Park), Syria (western and northern), Trinidad & Tobago (Port of Spain) and United Kingdom (London).  Cure Violence has also provided training in violence prevention techniques to representatives from dozens of other countries.

Several Cure Violence program sites have been externally evaluated, demonstrating strong results in multiple sites.  In June 2009, U.S. Attorney General Eric Holder, Jr. referenced Cure Violence as  a “rational, data-driven, evidence-based, and smart approach to crime.” The Economist termed the Cure Violence method “the approach that will come to prominence.”

A Few of Our Partners

Cure Violence Global Staff

Gary Slutkin, MD — Founder and CEO


Founder and CEO, Cure Violence

Formerly, Chief, Intervention Development, World Health Organization

Gary Slutkin is a physician and epidemiologist who has led efforts to combat epidemics of tuberculosis, cholera and AIDS, worked in over 25 countries in east and central Africa, Latin America and Asia, consulted on SARS and Ebola, was the Director of Intervention for the World Health Organization and is currently tracking and advising governments on COVID19. Dr. Slutkin is also known for innovating with the epidemic control approach and leads the #9 NGO in the world, Cure Violence Global.

Dr. Slutkin received his M.D. from the University of Chicago Pritzker School of Medicine, and completed his internship, residency, and infectious disease training at UCSF and San Francisco General Hospital (SFGH), where he was also the Chief Resident in Medicine. Following a year in Africa he returned to SFGH for infectious disease training, and was then asked to run the Tuberculosis Program for the City of San Francisco at a time when S.F. had the highest rate of tuberculosis in the country. Here he innovated with the use of local health workers, and this epidemic was reversed within 3 years.

Dr. Slutkin then moved to Somalia to work on TB and cholera epidemics full time and lived in Somalia for 3 years, guiding the work of TB control in 40 refugee camps consisting of 1 million refugees, and then co-guided the response to a devastating national cholera epidemic.

Dr. Slutkin was then recruited in 1987 by the World Health Organization (WHO) to join the newly forming WHO Global Program on AIDS where he worked in over 25 countries. He was assigned to lead the efforts to start the national AIDS programs with the 13 countries in the epicenter of the epidemic in central and East Africa. Dr. Slutkin also led World Health Organization’s efforts to reverse the AIDS epidemic in Uganda, and Uganda became the first country, and for over 10 years the only country, to successfully reverse its AIDS epidemic. He was then appointed Director of Intervention Development for WHO at Global Headquarters/Geneva where he formed and led a team responsible for guiding countries around the world in behavior change methods.

After 10 years abroad, Dr. Slutkin returned home to the U.S. and shifted his focus to violence, seeing it as an epidemic process since the charts, maps and graphs as well as other epidemiologic characteristics appeared to define it in that way. He is credited with having fully revealed the scientific and practical links for seeing and treating violence more as a standard health epidemic. In the year 2000 he founded Cure Violence which has achieved 40 – 70% drops in violence – and sometimes to 90-100% using these methods. The approach is summarized in the 2013 Institute of Medicine Report, “The Contagion of Violence”, and in his article in that volume entitle “Violence is a Contagious Disease”. Seeing and treating violence as a health problem changes our view of people as well as the approach to the problem.

Cure Violence works in over 100 communities in 25 U.S. cities and 15 countries with the focus abroad in Latin America and the Middle East. There have been multiple independent evaluations of the work, and several heavily impacted communities have gone to zero shootings or killings for 1 to 3 years with this approach.

New initiatives for 2019 include expanding the national effort to design more complete systems for community health and safety, and an exploration of health-based intersections with the justice reform movement – in language, policy, systems and metrics. The international work is focused on reducing the stresses to immigration through violence reduction in Latin America, and a new approach to conflict zones focusing on the Middle East in particular Syria, Israel and the West Bank.

Dr. Slutkin’s work has been featured as the NY Times Sunday Magazine Cover Story, “Blocking The Transmission of Violence”, the award winning documentary film, “The Interrupters”, and in over a dozen books, most recently in Nicholas Kristof and Cheryl WuDunn’s book, “A Path Appears”. He also has a very highly acclaimed TED Talk. He has appeared on The PBS News Hour, CNN, 60 Minutes, and is quoted regularly in the NY Times, Wall Street Journal, Washington Post, USA Today, The Guardian, Financial Times, The Economist, and other leading publications. National and international awards include the U.S. Attorney General’s Award for Public Safety, The Order of Lincoln Award, and the UNICEF Humanitarian of the Year Award.

Dr. Slutkin speaks regularly at local, national and global forums including The World Bank, Institute of Medicine, The World Economic Forum, and the UN. He is a Global Ashoka fellow, and is a senior advisor to the World Health Organization.

Violence Interrupters, Outreach Workers, Hospital Responders, Supervisors from around the world

Cure Violence is centered on the work at the community level, implementing the health approach to prevent violence.  As an organization, we are guided by the work in the community.  Below are a few pictures of Cure Violence teams:

Michael “Mikey” Davis — International Trainer

Michael Davis was brought up on the south side of Chicago in the Auburn Gresham and Englewood communities, the oldest of three siblings. With his father incarcerated since Michael was an infant, serving a 20-year prison sentence, and his mother going through issues with drugs, Michael worked hard trying to be a big brother and a provider for his siblings. He was introduced to the streets at a young age, becoming involved in street activity at just 11 years old. At 15, Michael was incarcerated for armed robbery and sentenced to six years at a medium security youth detention center. While there he met two Cure Violence interrupters, who regularly gave presentations at the facility. He began engaging with one of the interrupters who was from his community. This interrupter came to pick him up when he was released from detention three years later.

Upon reentering society at age 18, Michael made the decision that he wanted to be a better role model for his siblings and to give back to the communities he’d taken from in any way he could. As he searched for employment with the help and mentorship of the Cure Violence interrupter, he began volunteering at the Cure Violence program in his community, as well as with other violence prevention efforts. The interrupter introduced Michael to Joakim Noah (former Chicago Bulls basketball player) and he began volunteering at the Noah’s Ark Foundation. Despite struggling to find employment, Michael stayed focused and positive with the help and support of his mentor and ultimately found a job. As times got better, he decided to use his past as a guide in helping the youth to find hope and a positive path forward.

He became a youth counselor, and then supervisor, at BAM (Becoming A Man), a program that teaches young men rights of passage and core values such as integrity, accountability, positive anger expression, and respect for womanhood.

Today Michael works as a National and International Program Specialist and Trainer for Cure Violence Global, training other credible messengers in violence detection, interruption, and behavior change in cities around the world.

Jarmain “Juice” Merritt — International Trainer

As a young child, Jarmain “Juice” Merritt moved from a small town to bustling Chicago. Despite the love and attentive care of his parents, Jarmain’s immediate environment shaped his early goals. Seeing others, including his older brothers, gain status and wealth through their actions led Jarmain to strive for the kind of influence and power that he saw could come from embracing risk and violence. Jarmain’s involvement with the criminal justice system began with his first arrest at age twelve. Between twelve and eighteen, Jarmain was in and out of juvenile detention so frequently that it began to seem like a revolving door between incarceration and freedom. During this period, Jarmain’s exposure to violence only increased.

While serving 19 years in prison for a crime he didn’t commit, Jarmain was introduced to a program that promoted a public health approach to nonviolence by a respected friend, Cobe Williams. Cobe had gotten involved with CeaseFire, which focuses on reducing gun violence through intervention and community mobilization. At the time, Cobe was an Outreach Worker with CeaseFire, and he started sending information about the program to Jarmain. Jarmain initially reacted with skepticism. He couldn’t reconcile the criminal goals he still had – which were all he knew – with Cobe’s talk of nonviolence and positive community impact. Gradually, Jarmain’s perspective changed as he saw how the program was changing his friend’s life, and as the logic of the public health approach – when led by credible messengers – resonated with his own thinking. Jarmain could see Cobe applying the same intensity Cobe had previously applied in a negative way to something that now had a positive effect on his community and in Cobe’s own life. Jarmain knew from his own experience that people are affected by their proximity to violence. He began to get involved with CeaseFire himself, and he began to share what he was learning with others throughout his community.

Jarmain started with Cure Violence first as a volunteer, then expanded his responsibilities as a consultant, and was ultimately asked to join the organization as a technical assistant. His role expanded, and Jarmain became a Program Coordinator. Building on his success in Chicago, Jarmain now travels extensively with Cure Violence, teaching others how to implement the Cure Violence model. Jarmain trains a broad range of people, from those with life experiences similar to his own to those who have no firsthand experience with. Jarmain and others on the Cure Violence team conduct assessments, go to high violence areas, and make recommendations on what can be done to stop the spread of violence. Jarmain has led programs and taught classes across the United States, training more than one hundred Program Managers, Directors, Outreach Workers, Community-Based Organizations and Violence Interrupters. The scope of his work is currently expanding internationally, with projects underway in Trinidad and Tobago and the Belize.

Jarmain brings his relentless passion to his work, and now applies the leadership and influencing skills he developed over the past three decades to helping others see new possibilities for themselves and their communities. Grateful to have the opportunity to pass on what he’s learned from his own life experiences, Jarmain uses his unique ability to understand the needs of others to connect with program participants in an authentic and powerful way.
Deeply committed to youth, Jarmain aspires to see violence reduction programs paired with valuable skills-based and entrepreneurial training programs so people can see a path out of violence that provides real opportunity for personal and community success.

Jarmain spends his free time reconnecting with family, including his kids and his grandchildren. He also enjoys playing chess with friends.
