History of the Traumatic Stress Institute

The original Traumatic Stress Institute (TSI) was founded in 1986 by Laurie Pearlman, Ph.D., Lisa McCann, Ph.D. and Dan Abrahamson, Ph.D. in South Windsor, CT. For 20 years, through it’s clinical service, the Traumatic Stress Institute/Center for Adult & Adolescent Psychotherapy (TSI/CAAP) and non-profit sister organization, the Trauma, Research, Education and Training Institute (TREATI), TSI’s mission was to contribute to the knowledge base about psychological trauma and its treatment through the development of theory, original research, and the integration of clinical work with both theory and research.

Among it’s accomplishments, TSI ran a post-doctoral psychology training program with seven graduates, treated more than 4000 clients, and sponsored the writing of 5 books on trauma treatment.  It influenced thousands of clinicians through presentations, workshops, and professional trainings, and direct clinical consultation. TSI was the breeding ground for much of the early conceptualization and theory building about the concept of vicarious traumatization.

In 2006, TSI sold its name and the license to be a national provider of Risking Connection training to Klingberg Family Centers in New Britain, CT. TSI is now a department of Klingberg Family Centers whose role is promote trauma-informed treatment both within Klingberg and internationally in settings serving trauma survivors. TSI of Klingberg does this via training, clinical consultation, and specialized evaluations related to psychological trauma.
