Mallory Trepanier, 
C.C.C., MEd., Registered Psych 

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.
