Our understanding of the individual-, community-, and society-level factors that contribute to crime and violence is rapidly evolving. The mounting scientific evidence of how trauma affects us, physically and mentally, is resulting in a paradigm shift in the provision of survivor services. And we are just now beginning to systematically investigate how technology is being exploited to commit crimes and how to prevent cybercrime. Crime prevention also is being revolutionized through new technologies and approaches.

DSG’s Justice Practice is devoted to reducing and preventing all forms of crime and violence – and to improving outcomes for juveniles and adults who come in contact with the justice system – through the study and application of evidence-based programs, practices, and interventions.

Every day our team of research scientists and consultants collaborates with other organizations and local, state, tribal, and federal justice agencies to apply what works to address some of the most pressing issues in juvenile and criminal justice.


Research and Evaluation

DSG engages in original quantitative, qualitative, and mixed-methods research to shed light on poorly understood juvenile and criminal justice issues. We also conduct systematic research reviews, meta-analyses, and secondary data analysis.

DSG is an established leader in assessing the evidence of criminal justice, juvenile justice, and crime victim services programs and practices. For the U.S. Department of Justice, we designed, developed, and manage two nationally recognized clearinghouses of evidence-based programs and practices.

Training and Technical Assistance

DSG works with juvenile and criminal justice organizations and agencies to build capacity, form strategic partnerships, maintain resiliency, and achieve sustainability. In addition to expert consulting, we design, deliver, organize, facilitate, and manage all manner of training and technical assistance, including in-person and web-based training.


We apply objectivity, rigorous analysis, and the best of science in its work with juvenile and criminal justice organizations to improve performance and service delivery by getting everyone working toward the same goals.



DSG provides first-rate writing and editorial expertise to help juvenile and criminal justice organizations effectively connect their message to their target audience.


DSG plans and produces trade shows, exhibits, conferences, and other thought-leadership events for groups of all sizes, adhering to the best practices and ethics of the meeting management profession.
