Captain Dieter A Josef
Lt. Matthew Longhini
My name is Captain Dieter Josef, and I have been a proud member of the Palm Beach County Sheriff’s Office (PBSO) since 1993. As the Commander of District 3, I oversee law enforcement operations in northern Palm Beach County, ensuring the safety and security of our community. District 3 is one of the largest unincorporated areas in the county, covering 102 square miles of oceanfront communities, urban centers, suburban neighborhoods, and rural landscapes. My leadership focuses on proactive policing strategies, crime reduction initiatives, and strengthening partnerships with residents, business owners, and community organizations. I am committed to fostering trust between law enforcement and the community through outreach programs, collaborative problem-solving, and direct engagement with local stakeholders. The men and women assigned to District 3 are dedicated to providing exceptional service, professionalism, and a steadfast commitment to public safety.
Throughout my career, I have held a variety of positions within PBSO. I began my service in a civilian role within the Procurement Division before pursuing formal training at both the Corrections Academy and Law Enforcement Academy. After completing my training, I embarked on my sworn career in the Corrections Division, where I was responsible for the care and custody of the inmate population. Within a few years, I transitioned to the Law Enforcement Division, gaining extensive experience in patrol operations and investigations.
My leadership and expertise have been demonstrated through various assignments, including roles in Internal Affairs, multiple Road Patrol districts, and as a Field Training Officer and Sergeant. I also had the privilege of working with the Eagle Academy, a “high school boot camp” designed to support and guide at-risk boys and girls between the ages of 13 and 16. My time there reinforced my passion for mentorship and helping shape the next generation. Additionally, I have served in specialized units such as the Honor Guard, Emergency Field Force, and Marine Unit.
In 2020, I was promoted to the rank of Captain and assigned as the Command Duty Officer (CDO), overseeing daily countywide operations. Before my promotion, I served as the Executive Officer in the Boca Raton district, where I played a key role in managing district operations and enhancing public safety initiatives.
Beyond my law enforcement experience, I am committed to continuous professional development. I hold a Bachelor’s Degree in Public Administration and am an alumnus of the prestigious Southern Police Institute, further strengthening my leadership skills and expertise in public safety strategies.
With over three decades of dedicated service, I remain focused on ensuring that District 3 continues to be a safe and thriving community for all who live, work, and visit the area.
