Rangemaster Staff

Over 2,600 people in the U.S. and nearly 100 people in Europe have taken our instructor development courses over the last few decades. We’re also fortunate to have dozens of Rangemaster alumni who volunteer to assist with classes when we teach in their locales. But beyond Tom and Lynn Givens, there are only five official Rangemaster staff members. Learn more about each of them below.

John recently retired from over 20 years of service in federal law enforcement, serving primarily in uniformed patrol. He currently serves as an instructor (firearms, tactics, active shooter, & use of force), an armorer, and supervisor for his agency.

John has been a Rangemaster Staff Instructor since 2001 and has helped teach armed citizens, law enforcement officers, and military personnel across the country.

Since 2005, John has been a researcher, author, and lecturer. He has been a speaker for the National Tactical Invitational (NTI), Rangemaster Tactical Conference, Indiana SWAT Officer’s Association, Georgia Tactical Officers Association, Indiana Sheriff’s Association, and the featured speaker at the International Law Enforcement Firearms Instructors Annual Training Conference. John has over 2,000 training hours in a variety of related fields.
