Trauma-Informed Therapy That Treats the Root, Not the Label

What Makes Therapy “Trauma-Informed”

SAMHSA (the Substance Abuse and Mental Health Services Administration) defines a trauma-informed approach through four commitments: an organization realizes the widespread impact of trauma, recognizes signs and symptoms in clients and staff, responds by integrating knowledge into policies and practices, and actively resists re-traumatization.

In practice, this means six principles guide every interaction. Safety: physical, psychological, and emotional safety is the first priority. Trustworthiness and transparency: you know what to expect and why. Peer support: healing does not happen in isolation. Collaboration and mutuality: the therapist works alongside you, not above you. Empowerment, voice, and choice: you lead the pace and direction of your own treatment. Cultural, historical, and gender issues: your identity, your history, and your community context are never separated from your clinical care.

These principles sound simple. Applying them consistently requires a practice built around them from the ground up. Most therapists have some training in trauma. Fewer have built their entire clinical identity around it. The difference shows up in how quickly trust is built, how carefully pacing is managed, and how deeply the work can go without retraumatizing the person it is meant to help.

Our Approach: Relational Psychodynamic Therapy as the Foundation

Turning Leaf Therapy is a relational psychodynamic and trauma-informed practice. This means we believe the therapeutic relationship itself is the most powerful clinical tool available for healing trauma, particularly trauma that occurred in relationships.

Relational psychodynamic therapy holds that human beings are formed, wounded, and healed in relationship. When the source of your pain was a person, whether a caregiver who was absent or unpredictable, a partner who was controlling or violent, a family system that dismissed your experience, or a community that devalued your identity, the healing has to happen in relationship too. No protocol or worksheet can do what a consistent, attuned, trustworthy human relationship can do.

This is not a passive process. In relational therapy, the therapist pays close attention to what happens between the two of you: the moments of trust and rupture, the patterns you bring into the room, the ways old relational dynamics replay themselves in new relationships, including this one. When a client who was chronically dismissed as a child tests whether the therapist will really listen, that test is not resistance. It is the material. Working through it is how relational patterns actually change.

Research supports this approach. A landmark review by Jonathan Shedler in the American Psychologist (2010) found that psychodynamic therapy produces effect sizes that increase after treatment ends, rising from 0.97 at termination to 1.51 at long-term follow-up. This “sleeper effect” suggests that psychodynamic therapy sets in motion psychological processes that continue producing change long after sessions stop. Additionally, psychodynamic therapy demonstrates lower dropout rates than trauma-focused CBT protocols, with one meta-analysis finding a relative risk reduction of 37 percent (p=0.049). When therapy honors the complexity of trauma rather than pushing through it, people stay.

Within this relational framework, we also draw on evidence-based modalities to address specific dimensions of trauma. EMDR therapy helps reprocess traumatic memories that remain stuck in the nervous system. Internal Family Systems (IFS) works with the protective parts that formed in response to overwhelming experience. Somatic approaches address how trauma lives in the body. DBT and ACT provide emotion regulation and distress tolerance skills. Cognitive behavioral therapy offers structured tools for managing symptoms. No single modality is sufficient for all trauma presentations. The relational psychodynamic framework is what holds them together and determines when each one is called for.

What Trauma Actually Is

Most people think of trauma as a catastrophic event: a car accident, a combat deployment, a violent assault. These are traumatic. But they represent only one category. Trauma is better understood as any experience that overwhelms your capacity to cope and leaves a lasting imprint on how you see yourself, other people, and the world.

“Big T” and “Little t” Trauma

Clinicians often distinguish between “Big T” trauma and “little t” trauma. Big T traumas are the events most people recognize as traumatic: abuse, assault, combat, natural disasters, life-threatening accidents, witnessing violence. These events are objectively overwhelming and often meet the diagnostic criteria for PTSD.

Little t traumas are the experiences that may not seem dramatic from the outside but leave a lasting mark on how you function. A parent who was emotionally unavailable. Being humiliated by a teacher in front of the class. Growing up in a home where conflict was constant but never physical. Being chronically overlooked, dismissed, or made to feel that your needs did not matter. Individually, these experiences might seem manageable. Cumulatively, they shape how you relate to yourself and others as profoundly as any single catastrophic event.

Many people who carry little t trauma do not identify as having experienced trauma at all. They minimize their experiences because “other people had it worse.” But trauma is not defined by what happened to you measured against someone else’s suffering. It is defined by how your nervous system responded and whether that response still runs your life. Research consistently shows that cumulative little t traumas can produce the same psychological and physiological effects as Big T events, including anxiety, depression, relational difficulties, and somatic symptoms.

Single-Incident Trauma

Accidents, assaults, natural disasters, sudden loss, witnessing violence. These events are identifiable, often time-limited, and typically recognized by others as traumatic. They respond well to targeted interventions like EMDR, which has demonstrated that 90 percent of single-trauma victims no longer met PTSD criteria after three sessions (Shapiro, 2001). Our PTSD and Complex PTSD Therapy page addresses this in depth.

Complex and Developmental Trauma

Prolonged, repeated trauma, especially during childhood. Abuse, neglect, chronic family instability, growing up with an addicted or mentally ill caregiver, exposure to ongoing domestic violence. The ICD-11 defines Complex PTSD as arising from “prolonged exposure to significantly threatening events from which escape is difficult or impossible.” Complex trauma does not just create symptoms. It shapes personality, attachment patterns, and the very architecture of the self.

Relational Trauma

Harm that occurred within significant attachment relationships. This is the category that a relational psychodynamic practice is uniquely equipped to address. When the person who was supposed to protect you was also the source of your pain, the wound is relational and the healing must be too. Relational trauma disrupts the capacity to trust, to be vulnerable, to receive care without suspicion. These patterns do not resolve through insight alone. They shift through experiencing a relationship that works differently. Our Attachment Therapy page explores this territory.

Medical Trauma

Not all trauma involves violence or abuse. A serious diagnosis, a traumatic birth, an emergency surgery, a prolonged ICU stay, or an invasive medical procedure can leave lasting psychological imprints. Research shows that 20 to 30 percent of ICU survivors develop PTSD symptoms, and approximately 9 percent of women experience clinically significant post-traumatic stress following childbirth. Medical trauma is uniquely disorienting because it occurs in settings that are supposed to help you, creating a painful confusion between safety and threat. Philadelphia is home to some of the country’s largest hospital systems, and many of our clients carry unprocessed experiences from medical contexts they were told they should feel grateful to have survived.

Intergenerational Trauma

Trauma transmitted across generations through family systems, attachment patterns, and emerging epigenetic mechanisms. Research has found that grandchildren of Holocaust survivors are overrepresented by 300 percent among psychiatric referrals. Intergenerational trauma is not abstract. It is the anxiety your mother carried that you absorbed before you had words. It is the emotional numbness your father modeled because his father modeled it before him. Our Identity Exploration Therapy page addresses the process of understanding how inherited patterns shape present identity.

Community Violence and Environmental Trauma

Between 2015 and 2024, Philadelphia recorded 3,839 gun deaths and 16,475 shootings. The Philadelphia Urban ACE Study found that 40.5 percent of adults witnessed violence in their community and 27.3 percent lived in a neighborhood they did not feel safe in. These are not peripheral statistics. They are the lived reality of a significant portion of the clients we serve. Trauma-informed care in Philadelphia requires acknowledging that many of our clients carry not just individual wounds but the cumulative weight of living in a city where violence, poverty, and systemic disinvestment are structural realities.

How Trauma Lives in the Body and Brain

If you have read Bessel van der Kolk’s The Body Keeps the Score, which has sold over 3 million copies and spent more than seven years on the New York Times bestseller list, you already have a sense of this. Trauma is not just a memory. It is a physiological state that persists in the body long after the event is over.

When you experience a threat, your autonomic nervous system activates survival responses: fight, flight, freeze, or fawn. These are involuntary. You do not choose them. Your nervous system chooses them for you, based on what it calculates will keep you alive. The problem is that after trauma, this system stays activated. The threat is gone, but your body does not know that. You remain in a state of chronic hyperarousal (anxiety, hypervigilance, insomnia, irritability) or hypoarousal (numbness, disconnection, dissociation, fatigue), or you swing between both.

Dan Siegel’s concept of the window of tolerance describes the optimal zone of arousal where you can think clearly, feel your emotions without being overwhelmed, and engage with the world. Trauma narrows this window. Therapy, particularly relational therapy that provides the consistent experience of safety, gradually expands it.

Stephen Porges’ polyvagal theory explains this through the vagus nerve, which mediates three nervous system states: the ventral vagal state (safe and social), the sympathetic state (fight or flight), and the dorsal vagal state (freeze and shutdown). Trauma survivors often oscillate between sympathetic activation and dorsal shutdown, rarely accessing the ventral vagal state of safety and connection. The therapeutic relationship, when experienced as reliably safe, provides the co-regulatory experience that helps the nervous system learn that safety is possible again.

Signs That Unresolved Trauma May Be Affecting Your Life

Many people who benefit from trauma therapy do not initially identify as having experienced “trauma.” They come to therapy for anxiety that will not respond to logic, depression that does not lift despite changes in circumstance, relationship patterns that repeat no matter who the partner is, or a persistent feeling of being disconnected from themselves.

Unresolved trauma often shows up in ways that do not look like trauma at first:

• Emotionally: reactions that feel disproportionate to the situation, chronic anxiety or dread without a clear cause, emotional numbness or difficulty feeling anything at all, shame that permeates your sense of self, hypervigilance and difficulty relaxing.
• Relationally: difficulty trusting, people-pleasing as a survival strategy, patterns of choosing unavailable or harmful partners, fear of conflict, pushing people away when they get close, expecting abandonment.
• Physically: chronic pain without medical explanation, persistent fatigue, tension you carry in your body, sleep disturbances, weakened immune system, digestive issues.
• Behaviorally: substance use, emotional eating, workaholism, avoidance of situations that trigger memories or feelings, dissociating during stress, difficulty being present.

These responses are not signs of weakness or dysfunction. They are adaptations. They are the strategies your nervous system developed to survive an environment that was not safe. Trauma-informed therapy does not pathologize these adaptations. It honors them as evidence of your resilience while helping you develop responses that serve you better now.

How Trauma Therapy Works at Turning Leaf

Judith Herman’s foundational three-stage model of trauma recovery, from Trauma and Recovery (1992), provides the roadmap for our work. It is not a rigid protocol. It is a framework that respects the pace and complexity of genuine healing.

Stage 1: Safety and Stabilization

Herman wrote that the first task of recovery is to establish safety, and that “this task takes precedence over all others.” Before any trauma can be processed, you need a stable foundation: a therapeutic relationship you can trust, skills for managing overwhelming emotions, and an understanding of what is happening in your body. This stage is not preliminary to the “real work.” It is the real work. For many clients, especially those with complex or relational trauma, this stage takes months, and rushing it undermines everything that follows.

Stage 2: Remembrance and Mourning

When sufficient safety is established, the trauma story can be told in depth, at a pace you set. This is not about reliving the experience. It is about transforming traumatic memory so it can be integrated into your broader life narrative rather than existing as an intrusive, fragmented presence. This is where modalities like EMDR, IFS, and somatic approaches are most directly engaged.

Stage 3: Reconnection

The final stage involves reconnecting with the world, with relationships, with a sense of purpose, and with a version of yourself that is no longer organized around survival. Herman’s core thesis: “The essential features of psychological trauma are disempowerment and disconnection from others. Recovery therefore is based upon empowerment of the survivor and restoration of relationships.”

Not everyone needs all three stages. Some clients come to therapy already feeling safe and needing help with Stage 2 processing. Others are primarily working on Stage 3 reconnection after years of isolation. The model provides a compass, not a script.

Trauma in Philadelphia

Philadelphia has a unique and important relationship with trauma. It was here, in 2012-2013, that researchers conducted the Philadelphia Urban ACE Study, which expanded the original CDC-Kaiser ACE framework to include five community-level adverse experiences: witnessing violence, experiencing racism, living in an unsafe neighborhood, being bullied, and living in foster care. This expansion fundamentally changed how public health professionals understand trauma, recognizing that individual experiences of adversity cannot be separated from the communities in which they occur.

The data was stark. Forty percent of Philadelphia adults had experienced four or more ACEs, nearly double the national rate from the original Kaiser study. Nearly 14 percent experienced adversity limited only to the expanded community-level categories and would have been entirely missed by the conventional ACE framework.

Philadelphia also carries the weight of structural violence: a poverty rate of 19.7 percent (nearly double the national average), the lowest economic mobility ranking of any major metro region in the United States (Raj Chetty, Harvard/Opportunity Insights), a gun violence epidemic that killed 3,839 people in the past decade, and racial disparities so stark that Black Philadelphians are 13 times more likely to be shot than white Philadelphians.

We practice in this city. Our clients carry this city’s history. A trauma-informed practice in Philadelphia must reckon with these realities, not as background context but as the daily environment in which our clients live, work, raise children, and try to heal. Our approach to life transitions, grief, identity, and LGBTQIA+ affirming care is shaped by this understanding.
