Meet Dr. Iris Antonopoulos

Ph.D., C.Psych.

As a Clinical Psychologist, I work collaboratively with individuals and couples by drawing on their capacity for growth to help them gain greater self-understanding and meet their desired goals. I believe therapy should offer a supportive, non-judgemental space where clients can explore their inner worlds.

​

My therapeutic approach is grounded in cognitive-behavioural therapy and other evidence-based methods such as mindfulness-based interventions, self-compassion, and emotion-focused therapy. I work with a variety of presenting concerns including posttraumatic stress & trauma, anxiety, OCD, depression, stress, disordered eating, bariatric surgery, perfectionism, and self-esteem issues. I am also trained in psychedelic-assisted therapy and offer preparation and integration sessions for clients engaged in non-ordinary states of consciousness. I offer WSIB-funded treatment as well.
