He is a NRA Certified Instructor for Pistol, Home Firearm Safety, Personal Protection and Range Safety and has been certified as a State of Illinois Patrol Rifle Instructor. He is a graduate of the famed LAPD Handgun Instructor Training School (HITS) under the tutelage of Chief Instructor Lawrence Mudgett. Doc Gunn has taken Tactical Medicine at Gunsite under the Late M-SGT Chris Dwiggins and modified these lessons to pertain to the average police officer or armed citizen who may find him/her-self caught in a gunfight. 

Tactical Treatment of Gunshot Wounds is a shooting course combined with what a non-medical professional can do to treat a gunshot victim immediately after a shooting. Special emphasis on the control of Hemorrhage, relief of Tension Pneumothorax and maintaining a simple Upper Airway is stressed, along with precise shooting with anatomical awareness in order to best neutralize our would-be murderers.


Since 2004, Doc has given his TTGSW course to elements of the USMC, Federal, State, County and Municipal Law Enforcement and countless "ordinary citizens and gun owners."
