Sheriff Ty Trenary

Sheriff Ty TrenaryAs a veteran public safety official, Sheriff Ty Trenary has served in law enforcement since 1988.  Ty became the Snohomish County Sheriff in 2013 after serving in numerous leadership and executive roles within the agency.  The Sheriff’s Office motto, “Community First” reflects Ty’s commitment to partnering with communities and residents to make Snohomish County a safer place to live and work. Under his leadership, the Sheriff’s Office has received national recognition and achieved accreditation by the Washington Association of Sheriffs and Police Chiefs.


During his nearly six years in office, Ty has initiated several landmark programs at the Snohomish County Sheriff’s Office.  Realizing early in his tenure that Snohomish County could not arrest its way out of homelessness or addiction, Ty introduced sweeping changes in both patrol and corrections of the Sheriff’s Office.  Reforms included implementing booking restrictions at the jail, improving medical treatment inside the facility and launching one of the first jail medication assisted detox and treatment programs in Washington State.  Ty tackled these issues head on by working in tandem with the Bureau of Justice Assistance and the National Institute of Corrections.  He has also worked closely with the Major County Sheriffs of America, the International Association of Chiefs of Police, and the National Sheriffs Association.  The Snohomish County jail has recently been recognized nationally for implementing programs that address addiction and assist people with opioid use disorders.


Ty created the Office of Neighborhoods, which pairs deputies with social workers to work directly with homeless individuals who face crisis over addiction and mental health. He has also partnered with Human Services to facilitate opening the Diversion Center, a short-term shelter for homeless adults seeking solutions.  In 2017, the Sheriff joined the Snohomish County Executive, County Council, and Health District to launch the Opioid Response Multi-Agency Coordination Group, an effort to build on the county’s emergency management system to tackle the challenges of opioid addiction, mental health, and homelessness.  Ty was awarded the 2017 Snohomish County Human Rights Award for his dedication to protecting the rights and dignity of all Snohomish County residents, even the most marginalized and vulnerable.


Under Ty’s leadership, the Sheriff’s Office made employee and traffic-related safety a top priority.  The Snohomish County Sheriff’s Office was selected by the Governors Highway Safety Association to receive the 2017 Peter K. O’Rourke Special Achievement Award.  In addition, the Sheriff’s Office was also recognized as the Destination Zero Officer Safety Traffic Award by the National Law Enforcement Officer Memorial Fund.


Ty has a bachelor’s degree in Criminal Justice and is a graduate of Northwestern University’s School of Police Staff and Command.  Ty serves on several local, state and National Executive Boards.
