Katie Joosten, MSW, RSW, PMH-C

I hold a Master of Social Work degree (MSW) and am a Registered Social Worker (RSW) with the Ontario College of Social Workers and Social Service Workers, specializing in perinatal mental health, trauma recovery and grief. I bring 17 years of experience working in community counselling, health care, child welfare, and palliative care.

I am an EMDR Certified Therapist and a Certified Perinatal Mental Health Professional (PMH-C) through Postpartum Support International. I also work with couples using Gottman-informed therapy, including my role as a Bringing Baby Home Educator.

I do this work because I’ve seen how often people—especially parents—are expected to carry too much, too quietly. Pregnancy, postpartum, and parenting can surface anxiety, trauma, grief, and identity shifts that are deeply real AND treatable. My approach is person-centred, integrative, and evidence-based, drawing from EMDR, somatic approaches, ACT, and ERP to support healing at both the nervous-system and practical levels.

Therapy is about creating a safe, compassionate space where you don’t have to be perfect—just honest—and where real, sustainable change can happen.

Outside of work, I enjoy most of my time with my husband and two daughters. Being a bit of an introvert, I lean towards solo hobbies such as running (slowly), reading and playing the piano.
