James L. Greenstone's CV

There is an old proverb that says, "Fear not the path of truth for the lack of people walking on it." In my 50 years of practice and in my almost 39 years as a police officer, it has been my goal to prepare well and to seek the truth. Perhaps I can be of help to you and your clients. My expertise reflects work as the Director of Psychological Services for the Ft. Worth Police Department, a therapist, a teacher, an author, a police officer, a mediator and negotiator, and as a consultant. The field of Crisis Intervention has been my focus and I have written and published in this area. The specific area of knowledge most frequently asked about is that of police practices in a range of circumstances. These include, but are not limited to, training, use of force, critical incidents, hostage situations, suicide scenarios, stress management, barricaded subjects, psychological services, police procedures, tactical issues, handling the mentally ill, first responders and officer involved shootings. For the better part of my career as a police officer, I have worked extensively in the field of hostage and crisis negotiations. As a mental health professional and consultant and as a trainer of negotiators, as well as a member of hostage negotiations teams, I am knowledgeable about negotiator training, current practices in this area, dealing with suicidal and barricaded subjects, negotiations techniques, team development and team and negotiator interactions with police tactical units. I have participated in numerous hostage, barricaded and suicidal situations and have practical experience in all aspects of hostage and crisis negotiations team functioning. For many years, I trained most of the police negotiators in the North Texas area. I have trained many negotiators and crisis interveners both nationally and internationally. Additionally, my continuing work as a psychotherapist for the police officers and their families, as well as the general public .
