Our Mental Health Professionals

Adrien Tempier, BSc, MSc, MSc

Registered Psychotherapist (Qualifying)

Adrien has over ten years of international clinical experience in hospitals, community agencies, and private practice, and has recently returned from the United Kingdom. He is currently a registered psychotherapist (qualifying) and provides sessions under supervision at the Ebb Therapy Group in Ottawa.

Adrien aims to create a compassionate and safe space for clients to share their lived experiences. His practice employs an integrative scientist-practitioner approach, meaning that while he critically reflects on and draws from research evidence to inform his practice, he also stays close to clients’ lived experiences with curiosity and empathy. He helps clients understand the patterns, thoughts, and feelings they have toward themselves and others by exploring how these were formed through past and present relationships. This enables clients to reduce their distress, gain more control over their lives, and develop more meaningful relationships.

Adrien trained in counselling psychology and psychotherapy in both Canada and the United Kingdom, which has broadened and enriched his practice. Following graduate training in neuroscience, he sought a more holistic method of clinical practice that individualizes interventions to match the body-psycho-social-spiritual needs of clients. He specializes in humanistic, transpersonal, existential, relational psychoanalytic, neuroaffective, and cognitive behavioural approaches. He also draws from treatment interventions based on dialectical behavioral therapy, mindfulness, and motivational interviewing to support clients’ needs and goals.

Adrien provides therapy in both English and French.
