The NARM Framework

The Four Pillars of NARM

These four pillars guide the exploration of what drives behavior while maintaining moment-by-moment attunement in the therapeutic session.

1
Therapeutic Contract
Establishing a clear, collaborative working relationship grounded in the client's own intentions for healing and growth.
2
Deconstruction of Experience
Exploring how clients organize their experience — thoughts, feelings, sensations — to understand their adaptive survival patterns.
3
Supporting Agency
Reinforcing the client's sense of choice, self-direction, and authentic self-esteem — the heart of post-traumatic growth.
4
Psychobiologic Shifts
Acknowledging and working with the somatic, emotional, and relational shifts that signal authentic healing in session.
Why This Book

Essential for Every Trauma Clinician

Integrative Mind-Body Approach
Unifies relational, psychobiological, and psychodynamic perspectives into one coherent, non-pathologizing framework for developmental trauma.
Built on the Latest ACE Research
Integrates cutting-edge findings on adverse childhood experiences with clinical practice — arming psychologists, social workers, and therapists with practical tools.
Real Annotated Session Transcripts
Two full transcripts of NARM sessions with moment-by-moment commentary reveal the thought process and key choice-points — a behind-the-scenes look at NARM in action.
Reflective Exercises Throughout
Experiential exercises invite clinicians to deepen their own self-awareness — because the therapist's capacity for presence is central to the NARM model.
Non-Pathologizing Language
NARM de-pathologizes trauma symptoms, framing them as adaptive survival responses — a profoundly humanizing shift for both clinicians and clients.
For Clinicians & Laypeople Alike
Written with accessible, clear language. Many readers share passages with clients and loved ones — the insights are universal and deeply illuminating.

"Our vision is to bring humanity to the transformation of complex trauma. NARM is a therapeutic approach that supports reconnection to one's lived experience, so that clients can feel more fully alive — and become more fully human."

A heartfelt breath of fresh air for the field!
Whitney M. Sutherland, MA, LPC  ·  ✓ Verified Purchase  ·  August 19, 2022
This practical guide shows us how to actualize a more humanizing approach into reality. It elucidates straight-forward methods of refining our own relationship to ourselves to facilitate deep healing on an identity level, rather than a temporary behavioral or symptom-reducing level. The simple breakdown of core NARM principles allowed for greater ease, less effort, and significant self-trust in how to balance being directive while holding an open space for discovery.

Profoundly impactful "must read" for clinicians
Marcia Black, PhD  ·  ✓ Verified Purchase  ·  July 26, 2022
After 40 years as a clinical psychologist, I was moved and inspired to encounter NARM. It offers a unique integration of relational, psychobiological, and psychodynamic approaches that has transformed and enlivened my clinical work. The book teaches in a way that parallels the important themes being taught — it does what is rare in a clinical guide.

Invaluable resource for therapists and laypeople
Lisa Gillispie, LPC, SEP  ·  ✓ Verified Purchase  ·  July 26, 2022
This book does an excellent job of laying out the NARM model for working with developmental trauma. The two annotated session transcripts give us an inside look at each author's thought process — a peek behind the curtain. For therapists struggling with burnout or feeling stuck with clients, this chapter on the relational model will be incredibly useful.

Incredible Resource for Clinicians and Personal Growth

Even after studying the NARM model for 8 years and incorporating its principles in my practice, this book offered fresh insights. Anyone curious about what a NARM session looks like will find the two clinical transcripts invaluable. Many of my clients have started reading this and find it an illuminating resource in their own healing process.

I highly recommend this to anyone interested in deeper healing
Ryan Jones, LCSW CCTP  ·  ✓ Verified Purchase  ·  August 26, 2022
This is a crucial book for anyone treating trauma or interested in further healing their own. It provides a complete roadmap — from disrupted attachment to clinical process. NARM de-pathologizes trauma symptoms and positions them as adaptive, a notion that is itself healing. The concept of Agency and Protest Anger are absolutely vital to C-PTSD treatment.

Cutting-Edge and Accessible
Alex White, MS, LCMHC  ·  ✓ Verified Purchase  ·  August 15, 2022
Heller and Kammer observe the wisdom and strength that evolve out of traumatic experiences and seek to draw on those as resources for change. Many counseling books are laden with esoteric jargon. Here the authors distill a complex therapeutic model into clear, succinct concepts relatable for both new and seasoned practitioners — even for clients as a resource on their own healing journeys.

AMAZING RESOURCE for therapists and self-growth
Irem Akduman  ·  ✓ Verified Purchase  ·  August 2, 2022
NARM is a very compassionate and humanistic approach with a non-pathologizing language. This new book is a very comprehensive manual. The authors explained in considerable detail how NARM is used in sessions and how change happens, with actual case examples. The book also contains reflective exercises which deepen the reader's experience. I recommend it not just to psychotherapists but to anyone interested in self-growth.

Wonderful resource!
Peggy  ·  ✓ Verified Purchase  ·  December 8, 2025
This book takes a very complex subject and makes the information understandable, relatable, and usable. It even provides "scripts" for counselors to address adverse childhood experiences in their clients and gives them information to help resolve complex trauma. Written with empathy and heart, it gives therapists hope in helping their clients heal.

Transforming the way we understand trauma
Wendy Reiersen  ·  ✓ Verified Purchase  ·  August 4, 2022
Not only should every therapist read this book, so should every teacher, health practitioner, supervisor, and parent — anyone who interacts with people. We all have trauma. We heal through our relationships with self and others, and with generous quantities of acceptance and agency. It really is that simple. But read the book, and experience it for yourself!

A Tour De Force & Opus Magnum
Keith N.  ·  ✓ Verified Purchase  ·  August 22, 2022
The theoretical underpinnings are brilliantly aligned — informed by somatic work, relational therapy, bioenergetics, neurobiology, and attachment theory. The Four Pillars offer guideposts for the therapist to follow as sessions unfold, while the authors maintain a cogently focused enumeration of the model that never loses sight of the humanizing element. Magnificent!
