Andrea Kay
Registered Psychotherapist (Qualifying)
Andrea Kay, MACP, RP (Qualifying), is a Registered Psychotherapist (Qualifying) with a deep passion for transformative, soul-rooted healing. A recent graduate of Yorkville University’s Counselling Psychology program, she brings a rich interdisciplinary background in environmental studies and journalism—fields that enhance her understanding of story, identity, and the interconnected systems shaping human experience. Her holistic approach integrates psychodynamic, cognitive-behavioral, existential, and humanistic modalities, all framed through a trauma-informed and client-centered lens.
She has had the privilege of supporting individuals in a variety of settings, including clinical placements, private practice (ATK Psychotherapy), and crisis response with Kids Help Phone. Authenticity, curiosity, and reverence guide her work, particularly in the realm of psychedelic-assisted psychotherapy. Deeply aligned with the healing potential of psychedelic medicines, she supports clients navigating treatment-resistant depression, PTSD, grief, ADHD, anxiety, and existential distress, with a strong focus on meaning-making, integration, and embodied healing. Passionate about psychedelic ritual, ethics, and integration, she walks beside clients as a steady companion, guided by their inner wisdom. To her, therapy is not about fixing what’s broken, but rather transforming survival into a life of purpose, presence, and personal truth.
Outside of sessions, she finds renewal in movement, nature, and meaningful connection. As a neurodivergent multitasker with a curious mind, she often juggles ideas and projects, fueled by spontaneous inspiration and an encyclopedic knowledge of random facts. A devoted cat enthusiast, she is enchanted by felines of all kinds—wild or domestic.
Brooke Enright
Registered Social Worker
I’m Brooke (they/she/he), a Registered Social Worker and counsellor with a trauma-informed, client-centred approach to therapy. I work primarily with adults experiencing depression, anxiety, PTSD, and trauma-related concerns, particularly when these challenges feel longstanding, complex, or difficult to shift through traditional therapy alone.
My clinical work integrates evidence-based modalities including Acceptance and Commitment Therapy (ACT), Dialectical Behaviour Therapy (DBT), and Internal Family Systems (IFS). I support clients in developing emotional regulation skills, increasing self-understanding, and safely processing past experiences that continue to impact their day-to-day lives. When appropriate, I also incorporate creative and reflective approaches to help clients access insight in ways that feel natural and meaningful to them.
I have experience working with clients from diverse backgrounds and lived experiences, including 2SLGBTQ+ individuals, neurodivergent clients, and people in non-traditional relationship structures. My practice is grounded in respect, consent, and collaboration, and I aim to create a therapeutic space where clients feel safe, understood, and supported, regardless of where they are starting from.
Therapy with me is thoughtful, flexible, and focused on helping clients reduce symptoms, build resilience, and regain a sense of stability, agency, and connection in their lives.
