More about
Celine du Tertre
Celine is the psychotherapist who blends science, soul, and a pioneering passion for exploration. Equal parts clinician, spiritual caregiver, and sound alchemist, Celine navigates the depths of human experience with a compass tuned to evidence-based practice and ancient wisdom.
Whether exploring the depths of the psyche, guiding clients through psychedelic experiences, unblocking voices with vocal activation, or finding stillness in meditation, Celine lives at the crossroads of the mind, body, and spirit.
Grounded in compassion but unafraid to explore the unconventional, Celine’s work is as multidimensional as the frequencies she loves to study — resonating with authenticity, curiosity, and compassion.
