A treehouse represents the deepest desires of childhood: a place where we find comfort, safety, security and freedom
At Treehouse Trauma Centre, we help children, teens and adults overcome the hardships—trauma, abuse, anxiety or stress—that keep them from living fully. Our person-centred, humanistic approach helps adults and children break out of unhealthy relationship patterns that undermine their inner strength and equips them to move forward with security, certainty and joy
Everyone deserves a place to be themselves.

About Céliane
Born in the Québec countryside, Céliane grew up in a busy household as the second oldest of five siblings. She believes in each person’s individuality regarding how they experience, desire, and strive for wholeness and health. She deeply values holistic wellbeing and believes that connection, authenticity, compassion, and empathy can foster healing and wholeness.
Introvert by nature, she enjoys exploring the outdoors through hiking or climbing, learning languages, making a mess in the kitchen or on a canvas, or entering fictional worlds printed in a book or projected on a screen.
Approach to Therapy
Céliane strives to invite clients to explore their unique and personal experiences in a safe and open environment. She considers individuals as relational beings in constant interaction with themselves, others, and the world – emotions, values and spirituality included – while on a quest for wholeness, balance, and health; a process which can also be disrupted by traumatic experiences.
Drawing from a humanistic-existential approach, she strives to help individuals move toward (re)connection. She also draws from other therapeutic perspectives, including Cognitive-Behavioural therapy, Narrative therapy; Gestalt therapy; Emotionally-Focused Therapy; play and art therapy.
