Mallory Trepanier,  C.C.C., MEd., R. Provisional Psychologist  | McAtee Psychology | Calgary

Registered Psychologist with the College of Alberta Psychologists - License No. 6154
Psychologists’ Association of Alberta

I am a Registered Psychologist, who’s worked 8 years in the field of mental health.  I am passionate about working with adults, children/teenagers, and families who have experienced loss and grief, intergenerational trauma, sexual violence trauma, domestic violence, addiction and mental health concerns including, PTSD, anxiety, dissociation and attachment related presentations.  


I have worked extensively with families and individuals in the nonprofit sector to support them in learning communication skills, relationship building skills,  and conflict resolution skills. As a trauma informed clinician, I value the importance of knowing the family’s history, stories, and relationships as a way of building a foundation for success in these areas.


My ideal clients are seeking a therapist who is authentic, holistic and intentional with how they support their clients. I full heartedly believe that your story is central to healing and that you have your own narratives, strengths and resources to heal in your own unique way and at your own pace. My goal is to support you as you navigate and learn new approaches in healing so that you can see direct changes in your quality of life and relationships. If this is something you are interested in exploring I would be more than happy to connect with you!
