Trauma Therapy in Oshawa, Ontario
Trauma Therapy for Adults in Durham Region — Oshawa, Whitby, Ajax, Courtice, and Bowmanville. Plus virtual therapy across Ontario and Nova Scotia.
Trauma changes how you experience yourself, other people, and the world. Long after something has ended, your nervous system can still react as though it is happening right now. I offer trauma therapy in Oshawa and virtually across Ontario and Nova Scotia, drawing on Cognitive Processing Therapy (CPT), Internal Family Systems (IFS) informed therapy, and Dialectical Behaviour Therapy (DBT). Together these help you build stability, process what happened, and feel more like yourself again.
I will be candid with you. I do not gloss over what you have been through or rush you past it. I listen closely, I explain what is happening in your nervous system so it stops feeling so confusing, and I tailor the work to you rather than running you through a script. Being trauma informed is the heart of how I work, and that includes a real commitment to anti-racist practice and to working well with neurodivergent clients, whose experiences are too often missed or misread in therapy.
In this video I share how I use DBT, IFS and CPT to help clients understand and heal from the effects of trauma
How Trauma Therapy Works at My Oshawa Practice
Where we start depends on where you are starting from. Trying to process trauma before you have the stability and skills to handle what comes up is often what makes people feel worse in therapy instead of better.
I think about trauma work in three layers.
Stabilization is getting your day to day steady enough to do the deeper work. Sleeping, eating, getting through the week without things falling apart, knowing what to do when emotions get big. For some people this layer is short. For others it takes time, and that is okay. That is real work, not a detour around the real work.
Skills are the practical tools you use to manage what comes up, in session and in your life. Riding out distress without making it worse. Coming back into your body after you have dissociated. Asking for what you need in relationships that may have taught you not to ask.
Processing is the deeper work of going back to what happened and helping your brain and body store it differently, so it becomes something that happened rather than something that is still happening.
Most people need some of all three, and the order matters. We figure out where to start together.
When Trauma Stays With You
How trauma shows up day to day is often not what people expect. You might not think of what happened to you as traumatic at all. You might do well at work, hold things together for everyone around you, and still feel like something underneath is off.
Trauma-focused therapy may help if you find yourself dealing with difficulty trusting people even when they have shown they are safe, trouble feeling safe in your own body, broken sleep or nightmares, avoiding the people and places that remind you of what happened, feeling numb or like you are watching your life from the outside, struggling with closeness, feeling alone even in a room full of people, staying on edge for no clear reason, carrying guilt or shame that it was somehow your fault, intrusive memories that arrive without warning, or reactions that feel far bigger than the moment called for.
What surprises a lot of people is that trauma also shows up in ways that do not look like trauma. Depression that will not lift no matter what you try. Perfectionism so old it feels like your personality. People pleasing, where saying no feels physically unsafe. Not knowing what you need, or not being able to ask for it. Oversharing with people who have not earned it, then feeling raw afterward. Suicidal thoughts that come and go in the background. Self-harm. Drinking or using to take the edge off. Eating in ways that do not feel within your control.
These are not separate problems sitting on top of trauma. For a lot of people, they are the trauma. They are what the nervous system learned to do to keep going when something was too much, too soon, or went on too long. It can take a while to see the thread connecting them, especially when each piece has been treated on its own.
PTSD, Complex Trauma, and Traumatic Invalidation
People often use the word "trauma" to mean different things, and it can be confusing to figure out which one fits your experience. The distinctions matter because they shape what treatment looks like.
Post Traumatic Stress Disorder (PTSD)
PTSD usually develops after a single event or a clearly defined period of time — a car accident, an assault, a medical emergency, witnessing something terrifying. The hallmark symptoms are intrusive memories or flashbacks, avoidance of reminders, changes in mood and thinking, and being constantly on guard. PTSD is what most people picture when they hear the word trauma.
Complex Trauma (C-PTSD)
Complex trauma develops when something painful happens repeatedly over a long stretch of time, often starting in childhood or in a relationship you could not leave. Think growing up with a parent who was emotionally unpredictable, long-term emotional abuse, ongoing neglect, or being in a relationship where the harm was constant but hard to name.
What makes it different from PTSD is less about the symptoms themselves and more about how deep they go. With PTSD, the trauma is usually something that happened to you. With complex trauma, the trauma is often woven into your formative years or your closest relationships, which means it shapes who you became, not just how you feel now. Your sense of self, your gut sense of whether people can be trusted, your default settings in close relationships — these get built on top of what was happening to you.
People with complex trauma do not always look like they have PTSD. You might not have nightmares or flashbacks. You might not be able to point to a single event that "explains" anything. What you may notice instead is a chronic sense that something is wrong with you, relationships that feel either too close or impossibly far away, shame that does not respond to logic, and a feeling of never quite being okay even when life is going well.
It is more common than people realize, and it often goes unnamed for years.
Traumatic Invalidation
Traumatic invalidation is a quieter form of harm and one I see often in clinical practice. It happens when your experiences, emotions, or perceptions are repeatedly dismissed, minimized, or contradicted by people who were supposed to understand you. A parent who told you that you were overreacting every time you got upset. A partner who insisted that things you clearly remembered did not happen. A family where the message, spoken or not, was that your feelings were too much, too sensitive, or wrong.
Over time, this teaches you not to trust your own feelings or instincts. You learn to second guess yourself, override what you actually feel, and look to other people to tell you what is real. It can leave you with the same nervous system symptoms as other forms of trauma — anxiety, hypervigilance, difficulty with closeness — even when you cannot point to a single event.
Traumatic invalidation is also a key piece of how Borderline Personality Disorder develops. Marsha Linehan, the psychologist who created DBT, described BPD as what can happen when an emotionally sensitive person grows up in a chronically invalidating environment. The intensity of emotion was already there, and so was the capacity for closeness — but without the experience of being understood, those traits became sources of suffering instead of strengths. If you have a BPD diagnosis, or have wondered whether you might, this is often part of the story.
It is not less serious than other forms of trauma. It is just less visible.
If you are not sure which of these fits your experience, that is something we can sort out together in a consultation.
Dialectical Behaviour Therapy (DBT) for Trauma in Oshawa
Dialectical Behaviour Therapy (DBT) was built for people whose emotions felt too intense to manage, and the overlap with trauma is significant. So much of what trauma does to the nervous system, the big swings, the shutdowns, the urges to do something that helps in the moment and costs you later, is exactly what DBT skills were made for. Working with a trauma therapist in Oshawa who actually knows the DBT model, rather than borrowing a skill here and there, means you have something solid to hold onto while we do the harder work.
I use DBT in trauma work two ways.
The first is stabilization. Before processing trauma in CPT or going deep with parts work in IFS, your nervous system needs to be able to handle the intensity. DBT skills like grounding, paced breathing, and crisis survival strategies give you something concrete to do when emotions surge and feel impossible to manage. For some people this is the foundation that makes the rest of the work possible.
The second is skill building for the long term. Trauma often leaves people without tools their early environment never gave them: how to tolerate distress, how to regulate emotion in real time, how to stay grounded in relationships, how to ask for what you need without shutting down or exploding. These are not personality flaws. They are skills, and they can be learned.
For some people, DBT skills for emotion regulation are enough to feel steady and capable again. For others, especially those with PTSD or complex trauma, or a specific event they need to work through, the next step is processing the trauma itself. That is where other therapies come in.
If you are looking for DBT therapy in Durham Region as a complete treatment program rather than as part of trauma work, you can read more about the comprehensive DBT program here.
Cognitive Processing Therapy is one of the most well-researched treatments for PTSD. It works by helping you examine and update the beliefs your brain formed during or after the trauma — beliefs that made sense at the time but are keeping you stuck now.
After trauma, the brain tries to make sense of what happened. In doing so, it often develops rigid conclusions such as:
-
“It was my fault.”
-
“I can’t trust anyone.”
-
“The world is completely unsafe.”
-
“I should have prevented it.”
-
“I am permanently damaged.”
These beliefs are not chosen — they are survival-based meanings the brain formed while overwhelmed.
CPT works by helping you examine and update these beliefs so they reflect reality rather than the moment of trauma.
What CPT Involves
CPT is a structured therapy typically completed over 12 sessions.
It focuses on how trauma is remembered and interpreted rather than repeated exposure to the event.
You will learn to:
-
Understand how trauma affects thoughts and emotions
-
Identify “stuck points” that keep you feeling trapped
-
Reduce guilt and self-blame
-
Differentiate possibility from probability
-
Rebuild a sense of safety and trust
-
Reconnect with values and future goals
Rather than simply “talking about what happened,” CPT teaches you a clear method for working through it.
Sessions include guided worksheets and between-session practice so your brain can gradually update how it stores the memory.
What Changes With CPT?
As treatment progresses, most clients notice that memories start to feel like something that happened rather than something still happening. Emotional intensity decreases. Self-blame softens. Avoidance reduces on its own as the underlying fear settles. Relationships feel safer to be in. The future starts to feel possible again.
The goal is not to forget. The goal is for what happened to stop running your life.
Is CPT Right for Me?
CPT is an active structured treatment that differs from integrative talk therapy. It involves structured sessions and between-session practice to produce meaningful, lasting change. Please reach out for a consultation to discuss if CPT is right for you.
Where CPT works mostly with thoughts and beliefs, IFS works with the different parts of you that hold trauma. Most people who have been through something painful know what it is like to feel pulled in different directions. One part of you wants closeness, another part is terrified of it. One part wants to move forward, another part is still protecting you from things that happened years ago.
IFS treats this as completely normal. We all have parts. After trauma, some of those parts get stuck in the roles they took on to keep you safe — the part that stays hypervigilant, the part that numbs out, the part that pushes people away before they can leave first.
In IFS work, we get to know these parts with curiosity rather than trying to get rid of them. We learn what they are protecting, what they are afraid of, and what they need in order to soften. The parts of you carrying the heaviest pain — what IFS calls exiles — can be supported and unburdened over time, rather than locked away.
I am an IFS informed practitioner with additional training in applying IFS to perinatal mental health.
IFS may feel more natural and less structured than CPT. Some clients want one or the other. Many do best with a blend. We figure out together what fits. If you want to learn more about how I can integrate IFS informed therapy to support your needs, contact me for a free consultation.
Birth Trauma and Perinatal Mental Health
Birth trauma is one of the most under-recognized forms of trauma. It can happen during pregnancy, labour, delivery, or in the postpartum period, and it does not require anything to have gone wrong by medical standards. What matters is how the experience landed for you.
You may be carrying birth trauma if you:
-
Have intrusive memories or flashbacks of your birth experience
-
Feel anxious or panicked thinking about future pregnancies
-
Were dismissed, rushed, or not listened to during labour or postpartum
-
Experienced a medical emergency, NICU stay, or loss
-
Feel disconnected from your baby or struggle with bonding
-
Feel like you cannot talk about your birth without people changing the subject
I have specialized training in perinatal mental health, and a personal understanding of this work. This helps me better understand the specific ways trauma intersects with pregnancy, postpartum, and parenting. This is not something every trauma therapist is trained in, and it makes a difference.
Domestic Abuse and Intimate Partner Violence
I bring clinical experience supporting people who are currently in abusive relationships, recently out of them, or carrying the impact of one from years ago. This includes emotional, psychological, financial, and physical abuse. The work requires a particular kind of care — understanding the long shadow that controlling relationships leave, the way self trust gets eroded, and the time it takes to feel like yourself again.
Your safety is my first priority, and that includes safety as you define it. There is no pressure to leave. I know leaving is not always possible, not always safe, and not always the right next step in the moment. Some people stay for years for reasons that make sense from the inside, and the work we do together can still be meaningful in that time. Other people are actively planning to leave, or have just left, or left a long time ago and are only now ready to look at what happened. Wherever you are in that, we can work with it.
I also stay well resourced in the supports that exist outside of therapy. If it would help, I can point you toward legal, financial, and shelter resources in Durham Region and across Canada — including services for people who are not ready to make any big moves yet and just want to know what is available.
Beginning trauma therapy can feel intimidating. Many people worry they will be overwhelmed, retraumatized, or pushed to share too quickly.
Effective trauma treatment is paced and collaborative.
Before starting processing work, we focus on readiness:
-
Understanding your symptoms
-
Learning grounding strategies
-
Building emotional regulation skills
-
Clarifying goals and boundaries
-
Creating a predictable session structure
You remain in control of the pace.
You are never required to share details before you feel ready.
Trauma therapy works best when your nervous system has enough stability to process without becoming flooded. Preparation is not a delay — it is what makes the treatment effective.
Healing from trauma can take time. Trauma therapy with Stephanie Campoli Psychotherapy typically involves a commitment of approximately 12 or more weeks of weekly sessions.
I also recognize that each person’s schedule, readiness, and financial circumstances are unique. I work collaboratively with clients to develop an individualized treatment plan that still remains adherent to the evidence-based treatment models I use.
Cost:
Individual Sessions (50 mins): $165
Sessions are eligible for full or partial coverage under many extended health benefit plans that include Registered Social Workers. I do not direct bill, but I provide receipts you can submit for reimbursement. If you are unsure whether your plan covers RSW services, the easiest way to find out is to call the number on the back of your benefits card
If anything on this page feels familiar, you are not alone, and you do not have to keep carrying it on your own. I offer a free 20-minute consultation so we can talk about what is going on for you and whether working together feels like the right fit.
