In 2012, she was promoted to Lieutenant where she then served as the Lieutenant of the Investigations Unit. In 2015, she was promoted to Police Captain in charge of Field Services. As the Captain of Field Services, the position she now holds, she managed the Patrol Division, K9 Unit, Traffic Division, Volunteer in Police Services, Police Explorers, Police Chaplains, Peer Support Team, and Police Reserves. Her commitment to community has been demonstrated time and again through her work and participation with our monthly neighborhood cleanup events.
Over her career, Captain Aguinaga has had an immense impact on the police department and fostered a strong sense of family amongst us. Affectionately referred to as, “Momma D,” by many at the department she will be greatly missed. We wish you well in your much deserved retirement, “Momma D!” Please help us in celebrating such an amazing person.
