I’m Katherine, a Registered Psychotherapist specializing in trauma recovery.

My practice is focused on providing evidence-based treatment to adults who have experienced trauma, specifically those who have treatment resistant symptoms or who struggle with disassociation.

I tailor my treatment plans and therapeutic modalities to fit each person’s needs, while also integrating the latest research and neuroscience.

Occasionally, I offer group art expressive therapy programs and am an approved provider for the Victim Quick Response Program+(VQRP+)

I welcome and honour people of all sexual and gender identities, racial identities, cultures, religions, spiritualities, abilities, and world-views.

Whether it’s your first-time seeking therapy, or you’ve never really found a good fit please reach out – I’d love to help you find the care you need.
