Sheriff Ty Trenary


Ty grew up in Washington State and graduated from Bethel High School in Spanaway in 1984.

He has served the citizens of Washington State as a police officer for over 25 years.  He started law enforcement in the Town of Eatonville where he also served as a D.A.R.E. officer until joining the Snohomish County Sheriff’s Office in 1991.

Ty has served the Sheriff’s Office for more than 20 years, working his way up from master patrol deputy to Captain of the agency’s North Precinct.  He has served Snohomish County as the contract police chief in the City of Stanwood from 2008 – 2012 and has held leadership positions on the Deputy Sheriff’s Association and the Management Team Association.  He has worked in patrol and community policing, as well as in the agency’s administration by managing the training unit and assisting with recruiting and hiring. Ty was sworn in as the Sheriff of Snohomish County on July 8, 2013, elected in November 2014 and re-elected in November 2015.

It was under Ty’s leadership that the Snohomish County Sheriff’s Office responded to the deadliest mudslide in U.S. history, overseeing everything from the rescue of 16 individuals on the first day to recovering the remains of each of the 43 victims who lost their lives. 

Ty's mission is "Community First". In 2015, he created the Office of Neighborhoods to address homelessness and untreated addiction and mental illness in Snohomish County.  He also charged the unit with finding unique ways to reach our county's most vulnerable residents.
