SERGEANT PETE BOLLINGER (Ret.)

 

Pete Bollinger first became interested in law enforcement while serving in the United States Air Force, where he attained the rank of Sergeant. While in the military, he obtained A.A. Degrees in Industrial Security from the College of the Air Force and Criminal Justice from Devils Lake College in North Dakota. After honorable discharge, Mr. Bollinger continued his education, obtaining a B.S. Degree in Public Administration from the University of La Verne and a Master's Degree in Management from the University of Phoenix.
 

Mr. Bollinger became a police officer with the Santa Ana Police Department in 988 and worked a variety of assignments throughout his career. First and foremost, he is proud that the majority of his work history has been on patrol. He has served in an undercover capacity, both purchasing and selling narcotics, in vice programs with prostitutes, transvestites and other dregs of society. Mr. Bollinger was fortunate enough to earn an assignment in Personnel, specifically in the background unit. He attained the rank of Sergeant and is now retired from the SAPD.
