About Laetitia Passemier

My name is Leti. I was born in France and currently live in Costa Rica with my partner Chi and my dog Amma. I’ve also lived in Italy, Spain, and the Netherlands.

I’ve been through my fair share of traumatic experiences – my parents’ bitter divorce, not seeing my dad for 25 years, a close friend’s death during high school, physical violence, unsuccessful fertility treatments, and a devastating breakup with my long-term former partner. Experiencing repeated heartache and anguish has allowed me to develop compassion for all those who are going through their own struggles.

Straight out of college, I worked for 16 years in the corporate world. When I finally left,  I was ready to live in fuller alignment with my values. At the time, I felt lost yet somehow lighter and freer.

I spent many months travelling through India and Southeast Asia, learning from spiritual teachers and deepening my yoga and meditation practice.

On my first psilocybin mushroom journey in Thailand in March 2018, I discovered something profoundly special. The awe and wonder of that first journey are beyond words. Soon after, I attended my first 10-day silent Vipassana retreat. These two experiences liberated me from the negative thought patterns that had plagued me for years.

Since then, I’ve been on countless psychedelic journeys. These medicines have helped me make peace with God and confront the reality of death.  They have helped me work through deep traumas. I’ve learned to forgive myself and others and to have faith in something bigger than myself. Day by day, I’m more connected with Mother Earth and the Spirit Realms.

I am honoured to hold space for those who want to share what they are experiencing on their mushroom journey.

I enjoy learning new ways to enrich my ability to serve people. I have studied Trauma-Informed Plant Medicine with Atira Tan, as an End of Life Doula with INELDA and as a Somatic Experiencing Practitioner with SE International.

Laetitia Passemier's approach to integration

I’m honoured to provide a safe, supportive, and compassionate space for your inner exploration.

My intention is to share psilocybin carefully, with reverence and wisdom.

I guide individuals through their micodosing and macrodosing journeys.

For microdosing, we work together to create a protocol, track your results, and maximize your benefits.

In preparation for larger doses, I listen to your intentions, answer your questions, and share tips to create an ideal set and setting.

During post-journey integration, I help you process your insights, find meaning, and apply the lessons in your everyday life.

Integrating psychedelic insights is crucial for lasting change. I use a Somatic Experiencing approach to help you tune into subtle body sensations as portals for accessing and integrating subconscious material.

Psilocybin provides a push into self-acceptance while Somatic Experiencing develops the somatic resources to sustain it.

Somatic Experiencing powerfully complements psilocybin sessions by grounding experiences somatically, discharging trapped energy, teaching self-regulation skills, and providing a customizable roadmap for integrating insights into daily life and routines.

These modalities empower individuals to take an active role in their healing process and self-discovery.
