Center for Injury Research and Prevention

CVP Scholars and Associates

In 2013, the co-directors of the Center for Violence Prevention (CVP), formerly the Violence Prevention Initiative, sought the input and expertise of a multi-disciplinary group of clinicians and researchers from across Children’s Hospital of Philadelphia (CHOP) to help set direction and priorities for the new initiative. CVP’s Scholars and Associates offer a unique perspective to the causes and impact of violence on our children and youth, as well as solutions.

The result is a powerful network of violence experts that helps CVP to be strategic and practical in its efforts, as well as nimble in our ability to respond to violence and crisis in our communities.
