Physician-led psilocybin therapy
Where the mountain
meets the medicine.
Private retreats grounded in published research, guided by a medical team, and held in the quiet shelter of the high country.
Our Practice
The practice.
Private, medically supervised psilocybin-assisted therapy retreats for individuals facing life's most difficult passages. One client or family at a time. No compromises.
Physician-Supervised Retreats
Private weekend retreats with full medical oversight. A physician, psychologist, and support team present throughout -- from airport arrival to departure.
Palliative and End-of-Life Support
For individuals facing serious illness, end-of-life distress, or existential suffering. Our clinical team works alongside your existing providers.
Evidence-Based Protocols
Protocols drawn from published research at Johns Hopkins, NYU, and Imperial College London. We measure outcomes and contribute to the evidence base.
Concierge-Level Privacy
No pricing on our website. No group bookings. Every retreat begins with a private consultation. Discretion is foundational.
Our Difference
01
A Physician at the Helm
Cedars and Spores was founded by Dr. Neal Kraus, a board-certified physician with an Executive MBA. This is not a wellness brand that contracted a doctor for credibility. Medical leadership informs every clinical decision, every safety protocol, and every aspect of your care.
02
Built for the Hardest Questions
Many psilocybin services focus on personal growth or general wellness. We specialize in working with individuals facing serious illness, mortality, grief, and existential distress. Our team does not shy away from these conversations. We were built for them.
03
One Client at a Time
Your retreat is exclusively yours. No shared sessions, no group dynamics, no strangers in the next room. Your physician, your psychologist, your support team -- all focused entirely on you.
04
The Mountain as Medicine
Our retreats take place in carefully selected mountain properties in the Colorado high country. The setting is not incidental. Altitude, forest, silence, and distance from ordinary life are part of the therapeutic environment. The mountain holds the space. We hold the safety.
The Evidence
Grounded in science.
“Psilocybin produced large and significant decreases in clinician- and self-rated measures of depression, anxiety, and death anxiety, and increases in quality of life and life meaning.”
Journal of Psychopharmacology, 2016 -- NYU Langone Medical Center
57–79%
of palliative care participants achieved clinically significant symptom reduction in anxiety and depression.
Systematic review, Palliative Medicine 2026
80%
showed sustained improvement at six-month follow-up after a single psilocybin session.
Griffiths et al., Johns Hopkins 2016
70–91%
reported decreased fear of death across 31 published studies on psychedelics and mortality.
Barr et al., Psychopharmacology 2025
Over the past two decades, leading research institutions have produced a growing body of evidence -- including systematic reviews, meta-analyses, and randomized controlled trials -- demonstrating that psilocybin-assisted therapy can reduce existential distress, anxiety, and depression in individuals facing serious illness. Effects have been documented to persist from six months to four and a half years. We take this research seriously. It informs our protocols, our screening, and our commitment to measuring outcomes.
