Wilson, Bradon
I began my career in the field of public safety and criminal justice at the age of eighteen as a student service officer for the Cal State University East Bay police department. I worked as a student service officer while studying to obtain my bachelor’s degree in criminal justice. During my time at Cal-State East Bay I also served on their Community Policing Advisory Board, which was my introduction to the world of community policing.
At the age of twenty-one I began my career as a law enforcement officer for the City of Hayward. I attended the Alameda County Sheriff’s Office 139th police academy and shortly afterwards I began my field training as a patrol officer. I served as a patrol officer until 2012 when I was assigned as the School Resource Officer for Hayward High School and the surrounding middle schools. During my time as a School Resource Officer I was in charge of the local Junior Giants outreach program as well as participating in the Gang Resistance and Education Training (GREAT) program.
I was eventually assigned as an acting Sergeant in 2016 and received a full promotion of the rank of Sergeant in 2017. As a sergeant I was assigned to Chabot College to act as their law enforcement liaison as well as director of campus safety and security from 2018 to 2019. In 2020 I was retired from the police department in good standing due to a work-related injury.
During my law enforcement career I also held ancillary assignments as a SWAT team operator and an arrest and control instructor. As a SWAT team operator I received training on team tactics and participated in training exercises such as Urban Shield. As an arrest and control instructor it was my responsibility to train officers on numerous areas such as searching, handcuffing, the use of force, and documenting such incidents.
After my law enforcement career ended I returned to Chabot College to act as the interim director of campus safety from 2021 to 2022. During that time I assisted in the implementation of the new parking system in use, the installation of a new security system, and consulted the college on various public safety matters as well. While I was the interim director of campus safety I obtained my Master’s degree in criminal justice from Lamar University. Before my graduation I was inducted into Lamar University’s honor society, Phi Kappa Phi.
This will be my first year as a part time faculty member for Chabot College and I am excited for the opportunity!
