Strengthening connections among criminal justice agencies, behavioral health organizations, and the community to improve wellbeing for people with mental health conditions or co-occurring substance use disorders.


Every year, more than 15 million criminal cases enter U.S. state courts with approximately 10 million of those cases leading to jail admission; about 20 percent of those individuals who are admitted have a serious mental illness.

People working in courts—such as judges, prosecutors, defense attorneys, and court administrators—oversee critical initiatives that can serve to identify people with mental health conditions or co-occurring substance use disorders, connect them to treatment, and, when appropriate, divert them to community-based supports. JMHCP supports initiatives such as court-based diversion programs, treatment courts, prosecution-led diversion efforts, and much more. These initiatives often combine court supervision with community-based treatment services, usually in place of incarceration.

Propelling Change: A Prosecutor Call to Action

Collaboration Spotlight

Hon. Janet R. Holmgren

As a judge, I have been uniquely positioned to bring criminal justice and clinical professionals together with community partners to develop and implement behavioral health diversion programs that offer hope and recovery to people whose lives have been devastated by addiction and mental illness. At the same time, these efforts promote public safety by dramatically reducing the likelihood that they will reoffend. The public safety and quality of life benefits of these programs to the individuals, their families, and the community can’t be overstated.

Judge Janet Holmgren, 17th Circuit Court, Illinois
