Learn More About Our Healing Center & Colorado Psilocybin Therapy
Where thousands of years of ancient wisdom meets evidence-based mental health care — a safe, fully legal, and deeply supportive space for psilocybin-assisted therapy, grounded in an IFS-based, ACT-informed clinical framework. Colorado is leading the nation, and we're proud to be part of it.
A Sacred Sanctuary for Healing & Self-Discovery
The Psychedelic Therapy Den in Denver, Colorado offers something genuinely rare — a safe, fully legal, and deeply supportive space where whatever arises in your inner experience can be met without fear. For thousands of years, cultures around the world have worked with psilocybin mushrooms for healing, insight, and spiritual growth. Today, Colorado stands at the forefront of bringing that tradition into regulated therapeutic practice.
We welcome clients at every point on their journey. Some come navigating depression, anxiety, PTSD, or trauma. Others arrive mentally well, seeking personal growth, creative breakthroughs, spiritual connection, or simply a deeper understanding of themselves. You don't need a diagnosis to benefit.
What makes our practice distinct is the clinical framework we hold around the medicine: Internal Family Systems (IFS) and Acceptance & Commitment Therapy (ACT). The medicine softens defenses and opens the door; the framework gives that opening direction and turns insight into lasting change.
This practice is not about a facilitator, a guide, or any one person. It's about the container itself — the safety it protects, the freedom it offers, and the profound possibilities that emerge only when fear is no longer part of the process.
You Are Your Own Healer
We believe deeply in the self-healing model of psychedelics. Psilocybin doesn't fix you — it reveals what's already within you, waiting to be integrated, understood, and transformed. Our role is to hold space, ensure safety, and offer skilled clinical guidance when it's needed.
Inner Wisdom First
The medicine illuminates what is already within you. We don't impose a therapeutic agenda — we create the conditions in which your own inner healing intelligence can lead the way forward.
Structure for Those Who Need It
For those who get stuck, who need support navigating difficult territory, or who benefit from structured therapeutic guidance — we're here. Clinical expertise is available, not imposed.
Returning to Self
Many of us live misaligned — diverged from our true values, with protective parts leading instead of our authentic Self. This work helps you find your way back to who you actually are.
How Psilocybin Therapy Works: Ancient Practice, Modern Evidence
Psilocybin is a naturally occurring, non-habit-forming compound found in certain species of mushrooms. In a therapeutic setting, it temporarily alters patterns of consciousness in ways that support emotional insight, expanded awareness, and meaningful self-reflection. A typical session lasts between two and six hours, depending on dosage, setting, and individual physiology.
Modern scientific interest expanded dramatically after a landmark 2006 Johns Hopkins study demonstrated both psilocybin's strong safety profile and the potential for lasting positive effects from a single guided experience. Since then, research worldwide has examined applications for depression, trauma-related symptoms, substance use, and anxiety.
Crucially, the neurobiological changes psilocybin produces — softened defenses, quieted self-criticism, increased openness — are precisely the conditions in which evidence-based therapies like IFS and ACT do their deepest work. The medicine creates the opening; the clinical framework gives that opening direction.
Neuroplasticity & New Neural Pathways
Psilocybin stimulates BDNF (brain-derived neurotrophic factor), promoting new neural connections that help the brain escape entrenched patterns of depression, anxiety, and trauma — often after just one experience.
Carhart-Harris et al. · Imperial College LondonDefault Mode Network Reset
Psilocybin temporarily quiets the brain's Default Mode Network — the region behind rumination, self-criticism, and "stuck" thinking — creating a window of genuine openness and psychological flexibility.
Carhart-Harris et al., 2012 · PNASPsychological Flexibility & Defusion
Emerging research links psilocybin's lasting benefits to increases in psychological flexibility — the central mechanism of ACT — and to a less-fused, more workable relationship with difficult thoughts long after the session ends.
Davis et al., 2020 · Watts & Luoma, 2020Access to Inner Parts & Patterns
The same softening of defenses that allows for emotional insight lets the protective parts of the psyche relax. From a grounded state of Self-energy, clients can meet old wounds with curiosity rather than avoidance.
Strong Safety Profile
Research consistently confirms psilocybin is non-addictive with an excellent safety record when administered in a structured, supervised context. Guiding an expanded state requires clinical skill, presence, and a deep commitment to safety.
Johnson et al., 2008 · J. PsychopharmacologyBeyond Symptom Relief
Many clients report increased clarity, emotional openness, spiritual insight, and long-term shifts in perspective — changes that extend well beyond symptom reduction into a different relationship with themselves and their lives.
Griffiths et al., 2016 · J. PsychopharmacologyThe Medicine Creates the Opening. The Framework Gives It Direction.
Psilocybin alone is not therapy. What turns a powerful experience into lasting change is the clinical structure built around it — preparation that meets you where you are, presence during the journey, and integration that translates insight into a different way of living. Our framework rests on two evidence-based modalities working together: Internal Family Systems (IFS) and Acceptance & Commitment Therapy (ACT).
Internal Family Systems (IFS)
A parts-based therapy that recognizes the mind as a system of distinct inner voices — protectors that work hard to keep you safe, exiles that carry old pain, and a calm, compassionate core Self beneath them all. We help you build a curious, non-judgmental relationship with every part of who you are, so the parts carrying burdens can finally be witnessed and released.
Acceptance & Commitment Therapy (ACT)
A modern, mindfulness-based therapy focused on psychological flexibility — making room for difficult thoughts and feelings instead of fighting them, unhooking from the stories the mind tells, and orienting your actions toward what truly matters to you. Recent research identifies psychological flexibility as a core mechanism through which psilocybin produces lasting change.
Both modalities pair naturally with psilocybin — the medicine itself softens defenses, invites openness, and lets protective parts relax, so the work of acceptance, defusion, and unburdening can unfold from a place of clarity rather than effort.
Individual & Group Psilocybin Therapy
The Psychedelic Therapy Den offers full-spectrum psilocybin-assisted therapy — preparation, guided sessions, and integration — in both individual and group formats. Both pathways use the same IFS-based, ACT-informed clinical framework. Choose the structure that best supports your goals.
Individual Psilocybin Therapy
The highest level of personalized care and therapeutic attunement. Preparation, the psilocybin experience, and integration are paced entirely around your personal history, emotional needs, and nervous-system capacity — anchored in our IFS-based, ACT-informed framework throughout every phase. Especially supportive for those working with trauma, depression, anxiety, grief, or major life transitions, in a completely private studio.
Group & Couples Psilocybin Therapy
A different but equally powerful pathway. Professionally facilitated group and couples sessions offer shared intention, relational insight, and the experience of being witnessed in a safe, supportive community — with the same IFS-based, ACT-informed preparation and integration as individual work. Well-suited for connection, creative or spiritual exploration, or a more accessible entry into psychedelic work.
Is Psilocybin Therapy Right for You?
Emerging research and clinical experience suggest psilocybin therapy supports healing across a wide range of emotional, psychological, and psychosomatic concerns. It is not appropriate for everyone — we conduct a thorough intake to determine whether this approach aligns with your goals, health history, and current supports. If it isn't the right fit right now, we'll help you find what is.
- Depression, including treatment-resistant depression
- Anxiety disorders, panic, and OCD
- PTSD and Complex Trauma (C-PTSD)
- Grief, loss, and prolonged bereavement
- Addiction and substance use recovery
- End-of-life distress and chronic illness
- Burnout, existential distress, and loss of meaning
- Stress-related physical conditions (headaches, digestive)
- Personal growth, self-discovery, and spiritual exploration
- Personal or family history of psychotic spectrum disorders
- Current use of antipsychotic medications
- Certain antidepressants (assessed case by case)
- Significant cardiovascular or kidney conditions
- Active psychiatric crisis requiring immediate support
- Pregnancy or nursing
- Under 21 years of age (Colorado law)
These conditions don't automatically disqualify — they require documented physician approval or additional assessment before services begin.

A little about me.
Outside of work, you'll usually find me exploring the outdoors with my dogs — whether that's hiking, biking, snowboarding, camping, or cruising around on a Onewheel. I'm a huge animal lover, and being outside is where I feel most at home.
Music is a big part of my life, too. I love producing music, discovering new artists, and catching live shows whenever I can. I'm always drawn to experiences that help me learn, create, connect, and stay present.
I'm also passionate about personal growth and helping people become more fully themselves. I don't pretend to have all the answers — in fact, one of the things I value most is knowing what I don't know and staying curious enough to keep learning. Growth, self-awareness, and continuous improvement are themes that show up in both my personal life and my work.
Lately, I've been working toward a more plant-based lifestyle. I'm an aspiring vegan, though definitely not a perfect one. Progress over perfection feels like the better approach.
At the end of the day, I care deeply about animals, meaningful connections, good music, time outside, and becoming a little better than I was yesterday.

Colorado's natural medicine regulations differ from traditional medical models. A prescription or physician referral is not required to access psilocybin-assisted therapy. State law does require preparation work with a licensed facilitator before any psilocybin session, and certain medical conditions require documented physician approval. These requirements exist to protect your safety.
