There are two Developmental Centers and one Community Facility that have Police Departments which operate under the Protective Services Branch.
When an incident occurs at a developmental center/community facility (DC/CF), a number of reviews occur to determine the contributing factors, develop plans to prevent recurrence and initiate corrective actions if necessary. Special investigations are conducted by PSB as a critical element of safeguarding the DC/CF residents. In response to specific recommendations, PSB operations and organizational restructuring has occurred, and the PSB is reviewing and revising all internal operating systems to ensure ongoing improvement. The Department and PSB leadership are achieving this with subject matter expert consultants.
Meet the Captain of each Department below:

Message:
As the Headquarters Captain, it is my goal to help each member achieve their personal best, so they may serve the community to the utmost of their ability.
I strive daily to help others understand what my father taught me each day before he dropped me off for school:
“It’s your attitude, not your aptitude, that determines your altitude.”
