Psilocybin Retreats in Denver, Colorado
Denver is one of the only cities in the country where a person can walk into a legal, licensed setting and take part in a group psilocybin journey guided by trained clinical facilitators. Nikki Fall, LCSW, a licensed psychotherapist and Colorado Natural Medicine Clinical Facilitator, leads this work alongside her colleague Camila Pastor, LCSW, through OUR HOUSE, the psychedelic healing community they co-founded. Their healing and trauma centered psilocybin retreat is built for people who want to experience a therapeutically guided journey, versus a recreational experience that many people have had. Many people come to Nikki and Camila after they learn that their unique therapy-backed process creates very different healing experiences and results, with preparation, a lot of care and support, community, a supervised journey weekend, and integration that turns insight into lasting change.
A Legal, Therapy Grounded Model
Colorado's Natural Medicine Health Act, passed by voters in 2022, created a licensing system for facilitators and healing centers. For Denver residents, this means the choice is no longer between doing nothing and taking an unregulated risk. Nikki's retreat journeys take place at a licensed Denver facility, led by clinicians who are also trained psychotherapists, not only medicine administrators. That distinction shapes the entire program. A facilitator who understands trauma can help someone build trust in the process before the journey even begins, hold a steady container during the experience itself, and guide the transformative work with integration afterward. Without that full arc, the insights from a psilocybin journey tend to fade. With it, they become tools a person can keep using long after the retreat program ends.
Each program follows the same three part structure, spread across roughly six weeks.
Preparation comes first and happens virtually, in small group sessions focused on mental and physical readiness, working with trauma and shadow material, and setting a clear intention for the journey ahead. Self paced coursework on dosing strength, journeying skills, and what to expect is also part of this stage, so participants arrive at the retreat weekend feeling informed rather than uncertain.
The journey weekend takes place in person in downtown Denver. It opens with an arrival session and a low dose journey, giving participants a chance to settle into the space, the nervous system, the medicine and the group before the larger dose experience. A full day high dose journey follows, held with facilitators and a nurse present throughout. The weekend closes with an integration circle the next morning, giving the group a chance to share and begin making sense of what came up before everyone returns home.
Integration continues in the weeks after the retreat through virtual group sessions focused on connecting mental and somatic shifts to daily life, along with practical exercises for staying open to thoughts and emotions rather than shutting back down into old patterns. This stage is often where the real change takes hold, since a single journey rarely does the lasting work on its own.
How the Program Is Structured
Psilocybin loosens rigid patterns of thought, which is part of what makes it useful for people carrying depression, anxiety, grief, or trauma that talk therapy alone has not fully reached. That same openness is also why a trauma informed frame matters so much. Nervous system regulation, self knowledge, and real trust in the process are built deliberately during preparation, not assumed. Facilitators trained in clinical trauma work can recognize when someone needs extra support, slow a moment down, or hold space for material that surfaces unexpectedly. This is medicine work built around the person, not the other way around.
Why Trauma Centered Care Matters
Nikki Fall is a licensed psychotherapist, psychoanalyst, and Colorado Natural Medicine Clinical Facilitator with years of experience working legally with psilocybin and ketamine in individual, couples, and group settings. She co-founded OUR HOUSE with her colleague Camila Pastor, LCSW, and together they bring clinical, somatic, and relational training to every retreat, supporting participants through safe openings and reconnection to themselves, to others, and to the world around them.
Camila Pastor holds a Master of Social Work from New York University, an EMDR license and is a Somatic Experiencing Practitioner (SEP) who trained with Peter Levine. Camila is also trained in IFS, MDMA, Ketamine and Ayahuasca facilitation and therapy, with certificates from Fluence and MAPS, and a Colorado Natural Medicine Clinical Facilitator license.
Camila and Nikki co-founded OUR HOUSE, offering psychedelic group therapy programs and retreats in Colorado, and New York, and they are licensed in both states.

Program cost covers the full six week arc: preparation sessions, the guided journey weekend at a licensed Denver facility, and integration circles afterward. It does not include the psilocybin itself, travel, or lodging, which participants arrange separately. A thorough mental health intake and medical screening is part of every application, since fit and safety come before anything else. This screening process helps Nikki and Camila understand each participant's history and goals, and it helps participants understand what to expect before they commit to a cohort.
What Is Included
The next retreat opens with virtual preparation sessions, followed by an in person journey weekend at a licensed facility in downtown Denver, and closes with virtual integration circles in the weeks that follow. Exact dates, times, and registration deadlines for the current cohort are listed above and are updated each time a new program is scheduled.
Current Cohort Dates
Anyone interested in joining begins with a free consultation to talk through fears, goals, and whether this retreat is the right fit. From there, a short interest form starts the intake and screening process. Spaces in each retreat are limited, since the program depends on close attention from Nikki and Camila throughout preparation, the journey weekend, and integration.
This is not a fast track or a shortcut. It is a supported, legal path toward healing, built by therapists who believe that lasting change comes from real preparation and real integration, not from the medicine alone.
