Greg began his career as a Distinguished Military Graduate of the U.S. Army Officer Candidate School at Fort Benning, Georgia. He then served as a commissioned officer of infantry soldiers. Later he became a police officer with the cities Atlanta and LaGrange, Georgia. In Atlanta he served as a Zone 3 police patrolman. In LaGrange Greg 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 law enforcement career. Greg then became a criminal justice professor at a Washington State community college. He’s also worked as a private investigator specializing in criminal defense casework for 16 years.
The origins of Greg’s expert witness casework can be traced to his service as an International Police Trainer in Iraq and Afghanistan. The U.S. Department of Defense and U.S. Department of Justice vetted his curriculum vitae and qualified him as a Subject Matter Expert in Police Practices and Procedures. Greg then deployed, lived, and worked with NATO Forces for over two years in active war zones. He supported and supervised the training of Iraqi and Afghan national police officers in Baghdad and Basrah, Iraq, and Kabul, Afghanistan. In summation, Greg’s experience as police officer, SWAT Team member, college professor, private investigator, and international police trainer affords him the moral and intellectual authority to analyze and explain complex police incidents and and law enforcement concepts to jurors in a manner they can easily understand.
