About Lt. Col. Dave Grossman

Lieutenant Colonel Dave Grossman , U.S. Army (Ret.) is the Director, Killology Research Group, an author, a speaker, and a former West Point Psychology Professor.

Killology is the scholarly study of the destructive act, just as sexology is the scholarly study of the procreative act. In particular, killology focuses on the reactions of healthy people in killing circumstances (such as police and military in combat) and the factors that enable and restrain killing in these situations.

Col. Grossman’s research was cited by the President of the United States in a national address, and he has testified before the U.S. Senate, the U.S. Congress, and numerous state legislatures.  He has served as an expert witness and consultant in state and Federal courts.  He helped train mental health professionals after the Jonesboro school massacre, and he was also involved in counseling or court cases in the aftermath of the Paducah, Springfield, Littleton and Nickel Mines Amish school massacres.

Col. Grossman has been called upon to write the entry on “Aggression and Violence” in the Oxford Companion to American Military History, three entries in the Academic Press Encyclopedia of Violence, Peace and Conflict and has presented papers before the national conventions of the American Medical Association, the American Psychiatric Association, the American Psychological Association, and the American Academy of Pediatrics.

Since his retirement from the US Army in 1998, he has been on the road almost 300 days a year, for over 19 years, as one of our nation’s leading trainers for military, law enforcement, mental health providers, and school safety organizations.

Col. Grossman is a US Army Ranger, a paratrooper, and a former West Point Psychology Professor.  He has a Black Belt in Hojutsu, the martial art of the firearm, and has been inducted into the USA Martial Arts Hall of Fame.
