Gary Quesenberry

Quick Facts

I have over 25 years of law enforcement and military experience and have extensive instructional experience with both domestic and foreign law enforcement agencies. I have served in the United States Army and am a veteran of Operation Desert Storm. I am also a certified firearms and tactics instructor who has developed and implemented both basic and advanced training courses for law enforcement agencies worldwide. 


I think that situational awareness is the most important thing that anyone can learn or practice. Realize that you can never fight what you don’t see coming.
Gary Quesenberry

Gary Quesenberry was born in the Blue Ridge Mountains of Virginia, where his parents taught him the value of hard work, patriotism, and commitment to family. His passion for the outdoors and patriotic spirit led him to enlist in the United States Army at the age of seventeen where he served in the 7th Infantry Division as an Artilleryman during Operation Desert Storm.

Shortly after being honorably discharged from the Army, Gary married his wife, Kelly and began his law enforcement career with the Federal Bureau of Prisons. There he served as a correctional officer and Special Operations Response Team (SORT) member in FCI Beckley, West Virginia, and United States Penitentiary, Atwater, California. After the events of September 11th, 2001, Gary left the Bureau of Prisons to become a Federal Air Marshal. There, he traveled the world in the service of his country and devoted his time to studying the areas of violence and predatory behavior.

Now Gary is the CEO of Q-Series LLC, a company that manufactures concealed carry holsters and he’s developed numerous basic and advanced level training courses focused on mental toughness, marksmanship, and defensive tactics. As a competitive pistol shooter, Gary has been featured on the History Channel’s hit television series Top Shot -Season 3 and Top Shot All-Stars. He has an extensive background in both domestic and foreign counter-terror training and has worked in both the private and corporate sectors to help educate others on the importance of situational awareness, and personal safety.

For the last twenty-six years, Gary and his wife Kelly have traveled the country together and raised three children – all three are now proudly serving in the military. Gary currently resides in New Jersey where he is planning his retirement from federal service and one last move back to his hometown of Hillsville in the mountains of Virginia.
