Meet our Speakers!

Colin A. Ross, MD completed medical school at the University of Alberta and his psychiatry training at the University of Manitoba in Canada. He is a Past President of the International Society for the Study of Trauma and Dissociation, and is the author of over 225 papers and 32 books. He has spoken widely throughout North America and Europe, and in China, Malaysia, Australia and New Zealand. He has been a keynote speaker at many different conferences, and has reviewed for over 30 different professional journals.

Dr. Ross is the Director of hospital-based Trauma Programs in Denton, Texas, Torrance, California and Grand Rapids, Michigan. He provides cognitive therapy groups at all three locations, in person in Texas and by video-conference in Michigan and California. He has been running a hospital Trauma Program in the Dallas area since moving to Texas in 1991.

Dr. Ross’ books cover a wide range of topics. His clinical books focus on trauma and  dissociation and include: Dissociative Identity Disorder. Diagnosis, Clinical Features and Treatment of Multiple Personality, Second Edition (1997); Schizophrenia: Innovations in Diagnosis and Treatment (2004); The Trauma Model: A Solution to the Problem of Comorbidity in Psychiatry (2007); Trauma Model Therapy: A Treatment Approach for Trauma Dissociation and Complex Comorbidity (2009); Structural Dissociation: A Proposed Modification of the Theory (2013); and Treatment of Dissociative Identity Disorder: Techniques and Strategies for Stabilization (2018).

Dr. Ross has published a series of treatment outcome studies in peer-reviewed journals, which provide evidence for the effectiveness of Trauma Model Therapy. Many of his papers involve large series of cases, with original research data and statistical analyses, including a paper entitled ‘Trauma and Dissociation in China” in the American Journal of Psychiatry.

Besides his clinical psychiatry interests, Dr. Ross has published papers and books on cancer and human energy fields, as well as literary works including essays, fiction, poetry and screenplays. He has several different hobbies including travel.

Melissa Caldwell Engle, MS, LPC, ATR is a co-founder and co-owner of Healing Springs Ranch (HSR) LLC. She is a Licensed Professional Counselor (LPC) and a Registered Art Therapist (ATR). She has over 20 years of experience treating trauma and addictions in the behavioral health arena. Through her experience, she was able to create a truly unique clinical program for HSR that addresses all addictive patterns (substance and process) as well as all co-occurring psychiatric diagnoses during one treatment stay. Her integrated addiction model addresses the underlying function of all symptoms, which in turn eliminates the reasons behind most, if not all, continued self-defeating behaviors.

Melissa’s clinical background began with her role as the Executive Clinical Director of the Colin A. Ross Institute for Psychological Trauma. While in this position, she clinically managed three inpatient programs where she was involved in the development, certification, and implementation of the Trauma Model and its integration into the programs’ curriculum.  In addition to her administrative role, she also provided groups, individual therapy, supervision and consultation.  She has co-presented with Dr. Ross for over 15 years.

Mrs. Caldwell Engle is also a co-founder of the Trauma Recovery Associates (TRA 2002), which was originally created in response to the Catholic Church’s “sex abuse scandal” in 2002. TRA has since grown with its focus being to educate and foster the development of organizational leaders, human service providers, and trauma survivors themselves to respond more effectively to the impact of childhood trauma on individuals and on society. 

In addition, Melissa has also worked in her private practice for 15 years. She has worked with many behavioral health diagnoses including Depression, Dual-Diagnoses, Anxiety, Bipolar Disorder, Personality Disorders, PTSD, Eating Disorders, OCD, Dissociative Disorders and all addictive patterns and diagnoses both at the individual and group level.

She is an internationally recognized speaker on the effects of trauma, addiction and the comorbid client. She has a unique way of combining theory and specific treatment techniques emphasizing experiential/expressive treatment modalities. This combination allows her to reach a broad range of clinicians and participants. Her humor and case examples create a highly entertaining presentation style that makes her a recognized and sought after speaker.



In this workshop, Dr. Ross and Melissa Engle will describe how to recognize dissociative identity disorder (DID) and the principles of its treatment. In the morning Dr. Ross will describe the key symptoms of DID and how to ask about them in a clinical interview. He will then demonstrate how to use the Dissociative Experiences Scale (DES) and the Dissociative Disorders Interview Schedule (DDIS) to screen for and diagnose DID. Attendees will receive copies of the DES and DDIS by email for their own use. The second half of the morning and the afternoon will be spent on treatment. Principles of the therapy include: the central paradox of DID; the problem of host resistance; and talking through to the voices. Time will be spent on techniques for fostering inter-personality communication and cooperation, grounding and stabilization and other tasks. Techniques and strategies will be illustrated through case examples.
