Ellis Amdur balances two careers, that as a crisis intervention specialist, through his company, Edgework and as a 50+ year practitioner of traditional Japanese martial arts. His writing meets right in the middle. Through his company, Edgework Books, he has self-published twelve books on the verbal de-escalation of aggression and calming of agitated mentally ill people, one each for those in the social services personnel, for hospitals, for families, for police officers, for firefighters and EMTs, for parole/probation officers, for 911 call-takers, for security guards, correctional officers in a jail setting and for worksite safety (HR, threat assessment professionals, etc), some co-written. In addition, he has published two volumes Shapeshifting: Effective Scenario Training for Hostage Negotiation Teams, co-written with Fmr. Sgt. Lis Eddy. Amdur has also published Body and Soul: Toward a Radical Intersubjectivity in Psychotherapy, a combination of a lyrical description of how phenomenology and dialogal philosophy can be applied to psychotherapy, followed by two heart-wrenching accounts showing how these abstract principles are embodied in the real world. He has written and published three books on martial arts, the iconoclastic Dueling with Osensei: Old School, a work on classical martial traditions and most recently, Hidden in Plain Sight, on esoteric knowledge within various Japanese martial traditions. All three of these books, in revised, expanded editions have been - or will soon be - released by by Freelance Academy Press. Along with authors Neal Stephenson, Charles Mann & Mark Teppo and artists Robert Sammelin and Dean Kotz, Ellis has released the Jet City Comics graphic novel, the Cimmaronin. His first novel, The Girl with the Face of the Moon is published on Amazon KDP, with powerful paintings by artist Ben Trissel. His books are considered unique in that he uses his own experiences, often hair-raising or outrageous, as illustrations of the principles about which he writes, but it is also backed by solid research, and boots-on-the-ground experience.
