As a professional writer since 1978, Mr. Christensen has penned over 70 published books with six publishers, dozens of magazine articles, and edited a police newspaper for seven years. He has written on the martial arts, the paranormal, missing children, street gangs, school shootings, workplace violence, riots, police-involved shootings, nutrition, exercise, prostitution, and various street subcultures. Of late, he has been writing an award-winning police thriller fiction series called Dukkha. His short stories—OLD ED, BOSS, and Parts—are popular among fans of gritty action.

His books have been translated into five languages. Policing Saigon, On Combat, Cops' True Stories of the Paranormal, and Dead Body Calls are also available in audio at

The Masters Hall of Fame inductee began training in the martial arts in 1965 and continues to this day. Over the years, he has earned a 1st-degree black belt in arnis, a 2nd-degree black belt in jujitsu, and in 2018, the American Karate Black Belt Association awarded Loren a 10th-degree black belt in karate. As a result of his tour in Vietnam and nearly three decades in law enforcement, Mr. Christensen's focus in the martial arts—writing, teaching, and training—has always been on street survival, not competition. He has starred in seven martial arts training videos.


“Loren C scares us again, but not with ghosts, shadow beings, and UFOs. This time it’s with a peek into the minds of evil people.”

“I’m a long-time reader of Loren Christensen, and this one might be his best. Thought provoking and frightening.”

"On Combat examines the stress resulting from engaging in deadly battle and its effects on the human body, from the heart and the nervous system to visual and auditory perception to memory.

The historical perspective on the evolution of combat provided in this text further deepens our understanding of the brave men and women who train their minds and bodies to go to that place from which others flee."

"[Loren] asked men and women in uniform—police officers, sheriff deputies, SWAT, command, correction officers, and MPs—to convey their experiences with the paranormal. These are veteran officers that have been there and done that, but on one occasion they were confronted with the unexplained."
