Welcome to the Los Angeles County Probation Department’s website. It is an honor to lead the largest probation department in the nation, where our officers and staff work each day to serve, support, and positively impact our LA County communities.

Our department plays a vital role in public safety, rehabilitation, and justice reform. Whether providing essential services to youth in our care, supporting adults under supervision, or engaging with the community through outreach and resource events, we are committed to making a positive impact. Our employees go beyond their daily responsibilities, stepping up in times of need—serving as disaster service workers, assisting in juvenile facilities, and ensuring that those in our care receive the guidance and resources they need to succeed.

Collaboration is key to our success. We work closely with the Los Angeles County Board of Supervisors, Probation Oversight Commission, Superior Court, Sheriff’s Department, District Attorney’s Office, Public Defender’s Office, Department of Mental Health, Department of Health Services, Department of Child and Family Services, Department of Youth Development, and many other partners to reimagine probation and advance meaningful justice reform.

As we continue to evolve, our focus remains on strengthening rehabilitation efforts, expanding educational and vocational programs, and fostering opportunities for growth and success for those we serve. Through innovation, accountability, and community engagement, we are committed to shaping a department that is responsive, effective, and dedicated to the well-being of Los Angeles County residents.

Thank you for visiting our website and for your support of our mission. We invite you to learn more about the work we do and join us in building a safer, more just community for all.

In Service,

Guillermo Viera Rosa

Chief Probation Officer
