Therapy as a tool for living well, not just getting by
Something feels off. Not broken, exactly, but not quite right either. You're functioning, maybe even thriving by most measures, yet there's a gap between the life you're living and the one you want.
PRISMA is a boutique psychology practice in Yorkville Village built for people who take their inner lives seriously. We think of therapy as a tool you return to across different chapters of your life, not a problem you solve and move on from. Our team of registered psychologists, therapists, and an in-house nurse practitioner brings deep clinical training and a genuine belief that therapy should improve the quality of your whole life, not just put out fires.
Why PRISMA
Most therapy is built around crisis. PRISMA isn't. We work with high-functioning adults and couples who want more than symptom relief, and we've built a practice specifically around that.
A multidisciplinary team under one roof Our clinical team is led by Dr. Iara Da Costa, a registered psychologist with specialized training in Emotion-Focused Therapy (EFT) and ketamine-assisted psychotherapy. Alongside Dr. Da Costa, our therapists bring training across trauma-informed care, CBT, and EMDR. For clients whose care intersects with medication or psychiatric needs, Katie Langille, NP, holds a fellowship in medical psychiatry and works in the same building. No referrals to strangers. No fragmented care.
Progress you can actually measure We use Greenspace, a clinically validated measurement-based care tool, to track your progress with real data throughout therapy. You'll see what's shifting over time, not just feel like things might be getting better.
Registered, credentialed, and accountable Our psychologists are registered with the College of Psychologists of Ontario. Our therapists hold designations across social work and psychotherapy. Every clinician on our team was chosen for both their clinical depth and their ability to form the kind of therapeutic relationship that actually moves the needle.

Land Acknowledgment
PRISMA is located on the traditional territory of the Mississaugas of the Credit, the Anishnabeg, the Chippewa, the Haudenosaunee and the Wendat peoples. This territory is currently comprised of both ceded and stolen land. We recognize the persisting impact of the colonial invasion that resulted in genocide, forced societal assimilation, and intergenerational trauma on indigenous peoples. As Treaty people under The Dish with One Spoon Wampum treaty, we hold ourselves accountable to care for this land and take action to contribute to the continued healing of Indigenous communities. As part of this commitment and acknowledging that we have benefited from the teachings and wisdom of Indigenous communities, we contribute to Anishnawbe Health Foundation’s Traditional Knowledge Training Fund to be directed toward training for Traditional Healers, Ceremonialists and Osh-ka-be-wis.
