Founded in 1987 by Park Dietz, M.D., M.P.H., Ph.D., TAG, Inc., was the outgrowth of Dr. Dietz's unique combination of practical and research experience in injury prevention, the analysis of threatening communications, mental disorders, and criminal behavior. In the previous decade, from 1978-1987, he had advised the universities where he taught and numerous corporations on the risks associated with threatening employees and students, violent customers, extortion, bomb threats, and product tampering, and he saw that simply reacting to crises was not enough. A systematic, proactive approach was needed. From the start, TAG has focused on crisis prevention through early warning systems, early intervention, and the prompt and safe resolution of behavioral problems as they arise.
TAG's principles and training are based on the ethics, principles, and scientific findings of medicine, psychiatry, psychology, public health, and criminology. The first company to provide formal training in the field of workplace violence prevention (1993), TAG has partnered with many of the world's leading employers to develop innovative and best practices in workplace violence prevention and the management of misconduct in work settings. TAG's innovations are industry standards, and its procedures and training materials are widely imitated..
