- Take the OCD Test
Kate Caldwell believes that effective therapy is built on curiosity, collaboration, and a deep respect for each person’s unique story. Drawing on years of experience in psychotherapy, psychological research, and human behavior, Kate provides thoughtful, evidence-based care that helps clients move beyond survival toward meaningful, lasting change.
Kate is a Registered Psychotherapist who earned her Master of Arts in Counselling Psychology from Yorkville University after completing her undergraduate studies in French and Social Anthropology at the University of Edinburgh. Fluent in both English and French, she provides therapy to adolescents and adults throughout Ontario and Connecticut, creating an inclusive, culturally responsive space where clients feel safe to explore even their most difficult experiences.
Her approach integrates Cognitive Behavioral Therapy (CBT), Exposure and Response Prevention (ERP), Prolonged Exposure (PE), person-centered therapy, narrative therapy, and psychedelic integration, tailoring treatment to each client’s individual strengths, goals, and lived experiences.
Obsessive-Compulsive Disorder (OCD)
Providing evidence-based treatment using Exposure and Response Prevention (ERP), the gold standard for OCD, to help clients reduce anxiety, overcome compulsions, and reclaim their daily lives.
Racial Trauma & Post-Traumatic Stress Disorder (PTSD)
Utilizing trauma-informed therapies, including Prolonged Exposure and evidence-based cognitive interventions, to help clients safely process difficult experiences and restore a sense of safety and control, including individuals healing from race-based traumatic stress. Kate specializes in providing care that is culturally conscious and provides a safe space to process microaggressions and racial trauma.
Anxiety, Bereavement & Life Transitions
Supporting individuals navigating anxiety, grief, identity changes, and major life transitions through compassionate, individualized care focused on resilience and emotional well-being.
Psychedelic Integration
Offering specialized support for those seeking guidance in integrating meaningful psychedelic experiences into their ongoing personal growth and mental health journey.
Kate remains actively engaged in advancing evidence-based psychological care through clinical research and scholarly collaboration. Her work has contributed to peer-reviewed publications examining racial trauma, healthcare disparities, and psychedelic-assisted mental health care, reflecting her commitment to expanding access to culturally responsive, scientifically grounded treatment.
Her research includes innovative work on racial trauma treatment protocols, the impact of racial microaggressions in healthcare settings, and the evolving role of psychedelic medicine within psychological care. These contributions allow her to bring emerging clinical knowledge directly into her therapeutic work while maintaining the highest standards of evidence-based practice.

Before becoming a psychotherapist, Kate spent nearly two decades as a user experience (UX) researcher, consultant, and educator, leading qualitative research projects across North America and Europe. This background sharpened her ability to listen deeply, understand complex human experiences, and appreciate the many ways people make meaning of their lives.
Today, that same curiosity and empathy inform every therapeutic relationship. Kate believes each client is the expert on their own experience, and therapy works best as a collaborative partnership built on trust, respect, and shared goals.
Kate provides psychotherapy in both English and French for adolescents (12+) and adults seeking support with OCD, trauma, anxiety, grief, racial trauma, psychedelic integration, and life transitions. Whether you are beginning therapy for the first time or looking for specialized, evidence-based care, Kate is committed to helping you build resilience, gain insight, and create lasting change.
