Professor Gregory Gilbertson has owned and operated Gilbertson Investigations for 16 years. As an expert witness since 2014, Greg has provided expert analysis and opinion on 70excessive force, false arrest, officer misconduct, and self-defense cases in 14 states. He has also completed over two-dozen depositions and testified in both state and federal courts. Prior to becoming an expert witness, Greg focused solely on criminal defense casework for 12 years.
Greg and his colleagues now consult with civil rights and criminal defense attorneys nationwide. In a recent federal trial – Moises E. Ponce Alvarez v. King County Sheriff’s Office, the presiding U.S. District Court judge for the Western District of Washington entered the following ruling to defendant’s Motion in Limine to exclude Greg’s testimony:
“Mr. Gilbertson’s qualifications demonstrate extensive experience in policing…Mr. Gilbertson’s experience includes work as a police officer in Georgia…including assignments as a SWAT team officer, superior court investigator, school resource officer, stakeout squad officer, senior patrolman, and patrolman…After his law enforcement career, Mr. Gilbertson went on to become a college professor—where he taught courses in criminal justice — and a private investigator, conducting pretrial investigations for attorneys in hundreds of criminal cases…The Court finds that, based on his experience, Mr. Gilbertson’s testimony can be expected to have a reliable basis in the knowledge and experience of police practices.”
Expert Witness Casework: The origins of Greg’s expert witness casework can be traced to his service as a police officer, private investigator, tenured college professor, Guardian ad Litem, and International Police Trainer. The U.S. Department of Justice and U.S. Department of Defense have twice designated him a Subject Matter Expert in police practices and procedures. During two deployments to Baghdad and Kabul, Greg helped train Iraqi and Afghan police officers for 25 months in active war zones. His life experience affords Greg the ability to analyze and explain complex facts and circumstances to juries in a manner they can understand.
Greg began his career as a Distinguished Military Graduate of the U.S. Army Officer Candidate School. He then served as a commissioned officer of infantry soldiers. Later he became a police officer with the cities Atlanta and La Grange, Georgia. In Atlanta he served as a police patrolman. In La Grange he served as a senior police officer (Corporal), SWAT Team member, juvenile court investigator, and school resource officer. Duty related injuries and two major surgeries ended his career after eight years.
After leaving law enforcement, Greg became a criminal justice professor at Centralia College. The curriculum he designed and developed over two decades is now ranked in the “Top 10”of all criminal justice associate degrees in the United States by BestColleges.com. In addition, Greg recently led a groundbreaking academic initiative called “Crosswalk.” The Crosswalk process aligns police academy training and work experience with academic curriculum. As a result of this work, the Northwest Commission on Colleges and Universities has authorized Centralia College to confer 45 criminal justice credits to police officers and state troopers for academy training and work experience.
