CORE Investigations and Polygraph is owned and operated by Doug Brenn. Doug is a veteran of California Law Enforcement with over 25 years of service, and is a Licensed Private Investigator (CA P.I. License #25534). During his law enforcement career, Doug was a Sworn Peace Officer with the following Agencies: 1) Los Angeles County Sheriff's Department 2) San Bernardino County Sheriff's Department 3) Investigations Division - Department of Motor Vehicles
During the last 5 years of his law enforcement career, Doug served as the Deputy Chief for the Investigations Division of the Department of Motor Vehicles Southern California Law Enforcement Operation. After his retirement from law enforcement, he served as District Governor for the Inland Empire District of the California Association of Licensed Investigators. The Inland Empire District is comprised of approximately 160 Private Investigators.
Doug has received thousands of hours of training in all aspects of workplace, civil, and criminal investigations. As a result of the Workplace Investigations he has conducted, Doug has provided testimony in California State Personnel Board administrative hearings and in Criminal Courts. Due to his expertise in all aspects of investigations, he has been called upon to be a Training Presenter for both law enforcement and private investigations personnel.
If an investigation requires the interview of a six-year-old student in an Elementary School setting or a High-Level Manager in a business environment, Doug has the ability to transition his skill set and adapt it to any person, place, or circumstance. Equally as important, he understands the importance of "working with" Human Resources/Risk Management Department Directors, Executive Management and Labor Attorneys. A positive and cooperative working relationship with these key personnel in any Workplace Investigation is essential.
Doug has been certified through the State of California as a "Skelly Officer." This certification has given him a well rounded perspective on what constitutes an unbiased, thorough and competent workplace investigation.
Some of Doug's more complex Workplace Investigations have taken place at major educational institutions and corporations in California. His interview and investigative skills are "exceptional." He has dedicated his career to the "Art" of Interviewing and Investigation. His practical "decades" of investigative experience, combined with some of the "finest" training available in the nation, have given him the skill set to produce an exceptional investigative product.
Of noteworthy mention is the quality of his investigative reports. Without exception, his final investigative reports are always: Well Written, Thorough, Concise and Factual.
