My philosophy of treatment is the use of evidence-based and trauma-informed practices in a strength-based, multi-disciplinary approach. Helping clients become empowered in their own healing, I am trained in TF-CBT, Eye Movement Desensitization and Reprocessing Therapy (EMDR), and Structured Intervention Trauma-Child and Adolescent (SIT-CAP). I specialize in
trauma treatment, grief and loss, depression, stress, and anxiety issues for children, adolescents, and adults.
My specialized area of expertise is providing treatment to first responders and their family members. I also offer treatment for those individuals who are in the helping profession who may be experiencing PTSD or secondary traumatic stress. I have a strong knowledge of first responder culture which allows me to build connections and understand the role that workplace culture has one’s occupational stress injury. I offer one-to-one treatment for first responders and
also group therapy.
I have conducted training throughout the USA and Canada on topics such as line-of-duty death, victimology issues, sexual offenders, secondary traumatic stress and multi-disciplinary team approach to child abuse response and treatment.  I have conducted critical incident group debriefings for hundreds of front-line public health nurses and staff during the COVID-10 pandemic.

Hi! I’m Katie Koruna RP

As a registered psychotherapist, I offer an eclectic approach, combining the modalities I am trained in as well as that little hint of lived experience. I believe in the transformative power of an honest and understanding connection and I hope to become a support system for you, in the way that you need right now.

I hope you leave our work together feeling powerful enough to give yourself permission, to do the hard thing or to sit and just be. There is strength in taking that first step and I have the privilege of watching this happen. I work with folks across the lifespan and on all walks of life. I view client issues through a humanistic lens meaning I believe in the strength of the individual, their potential for growth and the client’s ability to overcome.  I want to help folks move from their anxiety, depression, trauma, attachment issues and all of the things that keep them feeling ‘stuck.’

An integrative approach means I draw from my training in EMDR (Eye Movement Desensitization Reprocessing), Cognitive Behavioural Therapy, Dialectical Behaviour Therapy, Trauma Focused CBT for Children and Emotion Focused Family Therapy (EFFT).  I have facilitated group therapy for kids and teens dealing with anxiety and have also co-facilitated critical incident debriefing sessions for teens.

Pairing instruction with intention, I dedicate time to helping others in Newmarket by volunteering with community meal programs. It is important to me to continue to give back to those in my community. Some of my hobbies include camping, cycling and reading as well as spending time with family.
