Dr. Sarah Thompson, C. Psych.

Sarah launched her part-time private practice in 2017 after thirteen years of full-time practice at the Centre for Student Development and Counselling at Ryerson University.  She has a deep interest in utilizing evidence-informed practice to assist individuals and couples in overcoming emotional and relational challenges.  Sarah works with clients to transform repetitive or stuck emotion and relationship patterns into the healthy and adaptive responses needed to support individual mental well-being and healthy and satisfying connections with loved ones.  The cornerstones of her practice include respect for each client’s lived experience, a focus on the intersecting identities that each person brings to their successes and challenges, acknowledgement and respect for the impact of systemic oppression on personal development and lived experience, and knowledge that, once safe environments have been reached, neuroplasticity and supportive relationships allow us to heal from past hurts.  Sarah practices Emotion-Focused Therapy from a trauma-informed perspective.  She draws upon her training in experiential, relational psychodynamic, and cognitive behavioural therapies to tailor her treatment to each client.

Sarah earned her doctorate in psychology at the University of Toronto (2006) and is a member of The College of Psychologists of Ontario (Registration #4417).

Stephanie Cosma, M.A., Clinician

Stephanie works with all of her clients to navigate difficult life changes, change old, stuck feelings, and explore and develop parts of the self that have been previously undiscovered or ignored. Her practice is evidence-based and rooted in empathy, curiosity, and openness. Stephanie views her clients as experts in their own experience, and fosters an environment where their needs are valid and their feelings are important. She works within an emotion-focused framework, and also draws on cognitive-behavioural and dialectical-behavioral orientations based on individual client’s needs, goals and preferences. She works collaboratively with clients in therapy, and provides a safe, accepting space for them to address emotional hurts and make sense of inner conflicts so they can begin to come out of their shell and thrive. Together, they explore the client’s personal patterns and environmental factors that contribute to emotional pain, and find sources of empowerment.
