Dennis Vrooman

Strategic Account Manager

Dennis Vrooman most recently retired as the Undersheriff of the Riverside County Sheriff’s Office (CA) after a 37-year law enforcement career.  He began his career with the Downey Police Department and was one of the original founding members of the newly formed Murrieta Police Department in 1992.   Dennis honorably “retired” from the Murrieta Police Department as a Captain in 2019.  He was immediately appointed Assistant Sheriff, then Undersheriff, with the Riverside County Sheriff’s Office where he was responsible for the management of a $850M budget and a department of nearly 4,000 employees.

Throughout his career, he served in a variety of patrol, administrative and investigative assignments at every rank.  He simultaneously served on the boards of several county-wide regional law enforcement and non-profit organizations.  At both the Murrieta Police Department and the Riverside Sheriff's Office, he managed or coordinated several capital and technology projects, including CAD/RMS projects and several other software system implementations.  He successfully coordinated the migration of the Murrieta Police Department into a regional P-25 radio system, then transitioned the management of the entire radio system into the Sheriff's Office while serving as Undersheriff.  He was able to facilitate other municipal police departments in the county onto the system and coordinated the connectivity of the system to neighboring counties.   Before his retirement, he set the foundational stages to lease/occupy a new regional sheriff's station from concept to opening within 14 months.

Dennis holds a Bachelor’s degree in Liberal Arts and a Master’s degree in Organizational Leadership.  He is a graduate of the Sherman Block Supervisory Leadership Institute, the FBI National Academy; and the Senior Management Institute for Policing (SMIP).  He and his wife have three grown married children and seven granddaughters.
