Greg Glassock

Founder & CEO After leaving Law Enforcement and recognizing a need for high-level firearms and tactical instruction to industry professionals, Greg founded Olympic Tactical & Investigations. He began networking with industry leaders and worked his way up to Assistant Lead Instructor for the Washington Criminal Justice Training Commission Private Security/Private Investigator and Bail Enforcement Agent Firearms Division. He became a leader surrounded by instructors who had more experience but did not let that slow him down and mastered all the disciplines offered by CJTC. Greg then spent the next few years finding and vetting out those instructors with the same drive and ethics as his own to build a team of industry leaders of his own. He did not stop with Washington State when he reached the top he looked around and found other states with the same needs. He made a push into Oregon and California as well and now holds instructor certifications for the west coast. Greg is not only an instructor but holds credentials to teach and certify Instructors. Greg is active in the development of curriculum for private companies as well as state and federal agencies.
