About Jose Marenco

Chief Jose Marenco’s career in law enforcement has spanned nearly three decades. 

After starting as a patrol officer with the Snoqualmie Police Department in 1996, he joined the King County Sheriff’s Office in 1998. He quickly distinguished himself as an exemplary detective, serving in several specialized investigative units, including Street Crimes, the Neighborhood Drug Enforcement Team, and the Criminal Investigations Unit. His path eventually led him to the Special Assault Unit and the Internal Investigations Unit where he continued his victim-centered approach and a commitment to integrity in policing. 

He was promoted to Captain in 2017 and spent several years with the Metro Transit Police, eventually taking over to lead this largest transit agency in the state where he enjoyed contributing to improving safety on transit for those that relied on it for mobility. 

He became the Chief of Patrol Operations in 2023, the Chief of the Criminal Investigations Division a year later and is currently the Chief of the Special Operations Division.

His long career has reached almost every major operational and investigative area within the King County Sheriff’s Office.

Chief Marenco is a graduate of the University of Washington and is most proud of his family; his wife and four children. In addition to Chief and Dad, he also holds the title of ‘coach’ from his days leading youth baseball and wrestling teams. His family remains his strongest motivation to serve the community and make it safer for everyone.  He credits his parents for his compassion and supporting those most vulnerable in our communities.
