Celine du Tertre
Mental Health Therapist Brooklyn, New York

I’m a licensed psychotherapist, spiritual caregiver, and psychedelic integration coach dedicated to supporting people through the complex terrain of transformation and awareness.

My work lives at the intersection of modern psychology, ancient wisdom, and intuitive healing practices.

Raised in a household that honored both structure and sensitivity—my father a military colonel, my mother an energy healer and published scholar in consciousness studies—I grew up with a deep appreciation for both the seen and unseen. This duality continues to shape my approach: grounded, clinical care held in a container of spiritual insight and cultural humility.

I hold a Master’s in Applied Psychology from NYU and have worked in NYC’s inpatient and outpatient clinics with adults and children from underserved communities. My clinical focus includes addiction, existential distress, grief, depression, and trauma. I’m a Certified Psychedelic-Assisted Psychotherapist through the Integrative Psychiatry Institute, trained in working with psilocybin, ketamine, and MDMA. My additional research and personal practices with Buddhist meditation and music therapy have further deepened my understanding of altered states, integration, and the power of the voice.

Over the last 7 years, I’ve also trained immersively with tribes from Peru and Colombia, drawing on the wisdom of both clinical and ancient traditions. I approach psychedelic integration as a sacred process of meaning-making, not as a problem to fix. I don’t divide experiences into “good” or “bad”—I believe even the most difficult journeys can become profound allies when held with discernment, curiosity, and integrity.

My work is holistic, relational, and integrative—combining somatic, transpersonal, and narrative therapies within a trauma-informed, multicultural lens. I specialize in vocal activation and the psychospiritual reclamation of voice as a tool for self-expression and embodiment.

If you’re navigating a psychedelic experience—or simply feel called to explore your inner world more deeply—I offer a collaborative space for reflection, awareness, and insight. Together, we can co-create a new story—one that honors where you’ve been, clarifies where you’re going, and walks you home to yourself.
