Testimonials: The following individuals endorse Professor Gilbertson as an expert witness in civil rights and criminal defense casework:

Darryl Parker, Attorney at Law, Seattle, WA: “Professor Greg Gilbertson has twice served as my retained expert in search and seizure and false arrest cases. His analysis and opinions were always spot on. I was most impressed with his willingness to take on and process a considerable amount of information. Methodical and thorough, he took the time to interview each client and determine for himself the veracity of the information they provided. His work ethic is extraordinary, and his credentials are unassailable. I would not hesitate to work with him again and highly recommend him to other attorneys.”

Patrick Trudell, Attorney at Law, Seattle, WA: I am a personal injury trial lawyer who has been trying cases in King and Snohomish Counties for over 30 years. I have worked with many experts including Police Misconduct Expert Professor Gregory Gilbertson. Professor Gilbertson was our expert witness in 2017 for a 42 U.S.C. 1983 case at the United States Federal District Court for the Western District of Washington. This case proceeded to a jury trial.

My co-counsel and I met with Professor Gilbertson at a local college. Professor Gilbertson was prepared for our meeting. He listened to our input on the facts of the case, took time to insure his understanding was accurate, and provided input on the police conduct in our case.  He also provided us with guidance on his direct examination, and on our cross examination of the respondent’s expert witness. We were never rushed and were able to bond with him as our expert. He left us knowing he was available for other pre-trial work.

Professor Gilbertson arrived early for his trial testimony. His direct examination went well. He engaged with the jury, his testimony was solid, and he was did not over advocate. On cross examination Professor Gilbertson was consistent in his testimony and his demeanor. He was a solid expert witness who testified with credibility. I recommend Professor Gilbertson as an expert witness in any case involving police misconduct and practice issues. We look forward to working with Professor Gilbertson in the future.”

Dr. Stephen Pidgeon, Ph.D., Attorney at Law, Everett, WA: Professor Gilbertson has again brought a high level of professionalism and competence to bear as an expert witness in our most difficult murder trial. Once the opposition made demands for a rushed expert witness opinion, Professor Gilbertson not only responded quickly, but eloquently, and his language and conclusion were dis-positive, the trial judge mentioning its credibility in hearings. We considered Professor Gilbertson’s contribution to be highly effective, and we intend to use him again when the necessity arises.” 

Michael Blanchard, Attorney at Law, New London, CT: “We used Professor Gilbertson as an expert witness in a criminal trial where self-defense was the primary issue. Greg was accessible, prompt, and thorough. He explained “use of force” and “self-defense” in a manner the jury easily understood. Greg’s testimony was an integral factor in achieving a not guilty verdict.” 

Nicholas Krakana, Scottsdale, AZ: “I reside in a gated community in Scottsdale, Arizona. My family and I were victims of a violent, warrantless forced entry of our home, based upon false pretenses, by the Scottsdale Police Department SWAT Team. We were then subjected to excessive force, false arrest, and defamation of character. Fortunately, I found Professor Gilbertson’s web site online, read his credentials, and contacted him. Professor Gilbertson was receptive and empathetic to my situation. I hired him to examine the facts and circumstances of my case. I am very pleased I did. His expertise and insight uncovered legal findings that solidified my position of victimization by the Scottsdale Police Department. Professor Gilbertson genuinely cares, and worked diligently on my case. I recommend Professor Gilbertson to anyone in need of his expertise.”

Greg resides with his wife Julie in Olympia, Washington. He is available for casework anywhere in the United States.
