National Network for Safe Communities

National Network for Safe Communities NNSC reduces violence, builds trust, and transforms public safety in partnership with communities around the world.

The National Network for Safe Communities, a project of John Jay College of Criminal Justice in New York City, was launched in 2009 under the direction of David M. Kennedy, and with executive guidance from Jeremy Travis. Our work focuses on supporting cities implementing proven strategic interventions to reduce violence, minimize arrest and incarceration, enhance police legitimacy, and strengthen

relationships between law enforcement and the communities it serves. The National Network recognizes that both law enforcement and the community must play a critical role in addressing these issues—but that neither can do it alone. Our strategies operate along the following guiding principles:

• First do no harm

• Strengthen communities’ capacity to prevent violence

• Enhance legitimacy

• Offer help to those who want it

• Get deterrence right

• Use enforcement strategically

We are committed to saving lives and saving communities by taking our strategies to a national scale and serving the nation’s most vulnerable areas. We represent and support our members by raising the visibility of their work, offering them strategic advising, recognizing and helping others learn from their work and innovations, providing peer support and learning opportunities, and conducting research and evaluations. Please visit www.nnscommunities.org for detailed information on the National Network’s mission, principles, strategies, research findings, media coverage, events, and membership.

How can communities adapt Group Violence Intervention (GVI) to better meet the needs of young people involved in serious violence?

In this National Network for Safe Communities webinar, practitioners from Philadelphia, Minneapolis, and Pine Bluff share early lessons from implementing youth-focused adaptations of GVI.

The discussion explores how communities are combining focused accountability with intensive wraparound supports, family engagement, mentorship, behavioral health services, education, and workforce opportunities to improve outcomes for youth.

Since 2016, we have supported Kingston, New York with designing and implementing our Intimate Partner Violence Intervention (IPVI). Partners in Kingston—and the larger Ulster County area—took a chance on doing something new to address intimate partner violence (IPV). This collaborative, multidisciplinary approach provided critical support to victim-survivors and engaged directly with those causing harm, thereby using a comprehensive response to violence. These efforts resulted in sustained reductions in IPV reoffending and established a model for coordinated response in Kingston.

As NNSC’s advising comes to a close in Kingston, we thank all the partners for their hard work, diligence, and commitment to addressing IPV. Over the years, partners have included: Kingston Police Department, Ulster County District Attorney's Office, Ulster County Department of Probation, New York State Department of Corrections and Community Service, Ulster County Crime Victims Assistance ProgramGroup, New York State Division of Criminal Justice Services, Family of Woodstock, Ulster County Sheriff's Office, New Paltz Police Department, Saugerties Town Police, Town of Ulster Police Department, and Ulster County Social Services Department.

When communities come together around data, partnership, and a shared commitment to safety, meaningful change becomes possible—that’s the power of partnership.

NNSC was honored to participate in the Seattle Violence Prevention Symposium, hosted by Councilmember Maritza Rivera, alongside leaders from across government and the community. It was a meaningful opportunity to better understand what Seattle’s data is telling us about gun violence and explore solutions tailored to the city’s unique needs.

Special thanks to our partners from Philadelphia, South Bend, and Baltimore for helping create a powerful space for learning,

collaboration, and action.

Join us for a virtual conversation on emerging efforts to adapt the evidence-based Group Violence Intervention (GVI) strategy for younger populations involved in serious violence.

While juveniles account for a relatively small share of those involved in gun violence, communities have a responsibility to respond in ways that recognize the unique developmental needs of young people. Effective intervention requires more than enforcement alone — it demands coordinated support, meaningful opportunities, and services tailored to adolescence.

Building on the core principles of GVI, this emerging work emphasizes intensive wraparound supports, family engagement, mentorship, behavioral health services, education, workforce pathways, and other youth-focused interventions. By strengthening connections to supportive adults and institutions and creating pathways to long-term success, communities can reduce violence and improve outcomes for young people.

Moderated by Sasha Cotton, Executive Director of NNSC, this webinar will feature practitioners and partners from Philadelphia, Minneapolis, and Pine Bluff — three jurisdictions participating in NNSC’s pilot efforts to adapt GVI for youth. Panelists will share implementation challenges, promising practices, and early lessons from the field, offering practical insights for jurisdictions exploring youth-focused violence reduction strategies.

Date: Wednesday, June 24, 2026
Time: 11:00 AM (ET) | 10:00 AM (CT) | 9:00 AM (MT) | 8:00 AM (PT) | 5:00 PM (CEST)

Alexis Acevedo, Senior Research Advisor, and Fatma Zahra, Director of Intimate Partner Violence Strategies, attended the 21st Annual Conference on Crimes Against Women, where they shared NNSC’s emerging research on the intersection of intimate partner and community violence. They connected with practitioners and emphasized the importance of trust building and collaboration across violence prevention fields to better support high-risk IPV victim-survivors.

NNSC is proud to support the ongoing work in Nashville, where partnership is driving real impact through our Group Violence Intervention (GVI).

Through our technical assistance, the city and its partners are seeing powerful early results: 86% of individuals who received custom notifications have not been rearrested for new violent offenses. That level of impact speaks to what’s possible when strategy, relationships, and support align.

This work is made possible through strong collaboration with the Metropolitan Nashville Police Department, the Nashville/Davidson County Health Department, and the Urban League of Middle Tennessee—the anchor agency leading social services and community-based support.

We were honored to participate in the Urban League’s first annual GVI Conference, bringing together leaders committed to building safer, more resilient communities.

The power of partnership is showing up in Nashville—and this is what progress looks like.
