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 and Professor of Epidemiology and International Health at the University of Illinois/Chicago School of Public Health. 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

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:

Marcus McAllister — International Trainer

Marcus McAllister joined CeaseFire Illinois (the program delivery partner for Cure Violence in Illinois) as a Violence Interrupter, and after serving in the position of Violence Interrupter was promoted to Outreach Worker. Shortly thereafter, Marcus was promoted to Program Manager where he managed two sites with a combined staff of 14 people. After successfully managing these sites, Marcus was asked to interview for a position as one of only three Cure Violence national trainers to help hire, train and set up replication Cure Violence sites throughout the world. Today Marcus serves in that capacity and oversees sites in NY, Philadelphia, New Orleans and Trinidad.

Marcus was born and raised in Los Angeles, California. As a child, he found himself shuttling between Chicago and Los Angeles, shifting between parents. Marcus was introduced to the gang & drug culture as a result of living in two cities with high rates of violence in America. At the age of 18 Marcus decided to return to Illinois to finish his last year of high school. Unfortunately, Marcus’s mother never got to see him graduate because at the age of 18, Marcus found himself in a federal court room in Chicago fighting a drug & gang conspiracy charge.  He was ultimately found guilty and sentenced to 10 years in a federal prison.  After serving 9 years of his ten year sentence, he was released in December, 1998. After release, he had difficulty finding permanent employment, wound up working odd jobs and narrowly avoided falling back to life on the street.

In 2005, Marcus was approached by CeaseFire Illinois (now known as Cure Violence) where his street background was considered an asset and his status as an ex-offender could actually be used to change lives for the good.  He became a violence interrupter, a highly-trained community health worker, whose job was to stop shootings and killings using a public health behavior change approach.  Since Joining Ceasefire, Marcus has devoted his life to helping others change their lives, just as CeaseFire helped him to finally turn his own life around.

Marcus has excelled in his role as a national trainer for Cure Violence, and was selected to receive the WARRIOR award from the King of Kings Foundation in New York City in June, 2015.  He was also awarded a New York State Assembly proclamation in recognition of his dedication and commitment to stopping violence in New York City, across the US and globally.

Marcus and his wife of 17 years live in the Chicago suburbs.  They are parents of a 14 year old daughter and a 10 year old son.  Marcus travels regularly and is a frequent guest speaker/presenter on the contagion of violence at events across the U.S.

Michael “Mikey” Davis — International Trainer

Michael “Lil Mikey” Davis was brought up on the south side of Chicago in the Auburn Gresham and Englewood communities, the oldest of 3 siblings. When Mikey was an infant, his father incarcerated with a 20 year prison sentence. With his mother going through drug issues, Mikey worked hard trying to be a big brother and a provider at such a young age. Mikey was introduced to the streets at a very young age, becoming active in street activity when he was 11 years of age. At 15 years of age Mikey was incarcerated for armed robbery and sentenced to a term of 6 years.

Upon reentering society at 18 years of age, Mikey made the decision that he wanted to be a better role model for his siblings and give back to the communities he had taken from any way he could. Mikey began volunteering with the organizations Safety Networks, Ceasefire, and Joakim Noah’s Noah’s Ark Foundation, while struggling to find a employment and struggling to not just give up.  Mikey stayed consistent and positive with the help of a great support system and a phenomenal mentor, continuing to push until something had come about. As times got better, Mikey decided to use his past as a guide in helping the youth of today see hope by being able to relate in age and everyday life which made a greater impact in his efforts.

Today Mikey works as a National and International Program specialist and Trainer for Cure Violence. Mikey now trains other credible messengers in cities around the world and is the youngest employed worker of the Cure Violence organization campaigning to stop the shootings and killings and mediating conflicts

Before coming to Cure Violence, Mikey was a BAM Counselor for The Becoming A Man program which teaches young men rites of passage and core values such as integrity, accountability, positive anger expression and respect for womanhood. Mikey became a supervisor for BAM over 7 elementary and high schools in Chicago before making the transition to his current role with Cure Violence. Working with Joakim Noah has been a dream come true for not only the youth of Chicago but for Mikey as well. The two of them set an example of compassion and care, conducting peace tournaments throughout the city bringing guys from different groups and neighborhoods together. Mikey lives every day of life believing and knowing “today is what you make it”. Great things have come his way as he sets out to help others that come from similar upbringings see that there is hope and anything is possible.

Gary Slutkin, MD — Founder and CEO

Gary Slutkin, MD

Founder and CEO, Cure Violence

Professor, Epidemiology and Global Health, UIC School of Public Health

Formerly, Chief, Intervention Development, World Health Organization


Dr. Gary Slutkin is a physician and epidemiologist formerly of the World Health Organization, the Founder and CEO of Cure Violence, and an innovator in health, behavior change, and data based approaches to local and global problems. Cure Violence is listed No. 9 among the top 500 NGOs in the World by The NGO Advisor, and 1st among NGOs devoted to reducing violence.

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.
