Dear fellow King County employee,

John Diaz, Director of the Department of Adult and Juvenile Detention

I am pleased to announce the appointment of John Diaz to serve as the new director of the Department of Adult and Juvenile Detention, effective Wednesday, August 21. His appointment is subject to Council confirmation.

John has served as Interim DAJD Director since April of this year, and during that time I have been impressed by his leadership, strategic thinking, and genuine interest in the work of DAJD employees, and the stability he has brought to the department.

Prior to joining King County, John was the Seattle Police Department police chief from 2010 – 2013, beginning his career at the department as a patrol officer in 1980 and holding many leadership positions before being named Chief of Police. He has three decades of senior management, law enforcement, and labor engagement experience.

I look forward to continuing to work with John and his leadership team on the work that DAJD employees do 24/7 in both custody and programming to keep King County a welcoming community where every person can thrive.

Sincerely,

Dow Constantine
King County Executive
