Moving up the Ladder

The St. Joseph Chargers boast many graduates in law enforcement.  They serve as far west as California with many more serving in the Chicago area.

Sergeant Sean Gilhooley, Class of 1991, started his law enforcement career with the Addison Police Department in 1996, serving as a patrolman in the Field Services Division before being assigned to the Investigations Section in 2001. 

Sean is a graduate of Lewis University where he received a Bachelor’s degree in Criminal Justice.  He has been trained as a Field Training Officer, Juvenile Officer, Evidence Technician, Bicycle Patrol Officer, Gang Specialist, Fitness Instructor and Defensive Tactics Instructor.  He was a member of the DuPage Major Crimes Task Force, DuPage Sex Crimes Task Force (SPEAR), Midwest Homicide Investigators Association, Midwest Gang Investigators Association and is currently a court certified expert in street gangs.

Sergeant Gilhooley is also a supervisor of the Department’s Community Response Unit and an Assistant Supervisor for the Major Crimes Evidence Technicians.  He is a member of the Critical Incident Stress Management Team for Police Officers and a member of the Northern Illinois Police Alarm System Mobile Field Force (NIPAS).

Sean was recently promoted to the newly created position of Administrative Sergeant, working with the department’s support services.  “I am looking forward to my new responsibilities,” remarked Sean. “I’ll be working with some of the leaders in different areas of the Addison Police Department, such as evidence and communication.  We have done some good things in Addison during the last several years and I see this position as building on that work.”


            We are very proud of this Charger and his work.  Congratulations, Sean!
