Sara Lewis, PhD, LCSW
Dr. Sara Lewis is co-founder of Memoru Center for Visionary Healing Arts with Marcela Ot'alora G. and Bruce Poulter in Boulder, CO. While at Naropa University, Sara served as Associate Professor and Chair of Contemplative Psychotherapy and Buddhist Psychology where she also co-founded the Naropa Center for Psychedelic Studies, and has trained upwards of 400 students in providing psychedelic-assisted therapy. She is the director of Memoru Center for Visionary Healing Arts’ Colorado-approved Natural Medicine training program.
As a psychotherapist and facilitator, Sara specializes in intergenerational and ancestral trauma. She loves to work within deep time and honors the wisdom and inner-knowing of her clients, as well as the inherent knowing of mushrooms, themselves. As a mother, she feels particularly called to work with parents and grandparents, and also is called to supporting end-of-life transitions, grief, and existential distress. Sara upholds her ancestral traditions of Celtic and Hungarian lineages, and is a long-time Vajrayana Buddhist practitioner.
Lost Garden is honored to supply natural medicine for Dr. Sara Lewis and Memoru’s talented team of licensed facilitators, dedicated to providing both clinical services and DORA-approved facilitator training.

Accurately dosing natural medicine can be daunting— We’d love to help you!
We understand that calculating the correct amount of medicine to equal the desired dosage of psilocin can be an intimidating task— and precision is vital!
To assist you, each Lost Garden natural medicine order comes accompanied by a Psilocin Dosing Guide. Each dosing guide is individually tailored to accurately reflect the potency of the specific harvest lot that the medicine came from. This guide exists for your reference and convenience when dosing our medicine.
Sample Psilocin Dosing Guide
Here’s a chart comparing the potencies of our proprietary cultures. This chart features our most recent test numbers for each culture, and is updated regularly as new test results become available.
Click here for more information about each individual culture.
Let us help you find the strain that best suits your facilitation style, or we can create a unique one specifically for your practice!
We’ve invested years into researching and refining our proprietary strains for consistency and the experience they deliver, making our offerings both reliable and ideal to be used in a vast range of therapeutic settings. We’ll work with you to select the best strain for your practice, or if you prefer, we would love to develop a proprietary strain exclusively for your healing center.
pharmaceutical-grade freeze-dried natural medicine options— available at the end of January!
Lost Garden is excited to offer
Why choose freeze-dried vs. conventional drying methods?
Air-drying will get the job done and is the main way natural medicine gets preserved for consumption. That said, the primary psychoactive compounds in natural medicine, psilocybin and psilocin, are heat-sensitive and oxidation-prone. Freeze-drying is a way to preserve the medicine that requires minimal heat and air exposure versus conventional air-drying methods. As a result, freeze-dried mushrooms maintain higher potency preservation and more closely resemble their fresh, natural state.
Our pharmaceutical-grade freeze-dryer is specialized to process delicate organic compounds at lower temperatures than a home freeze-dryer, preserving our proprietary natural medicine at top-tier, pharmaceutical-grade quality.
“In our quest to provide the absolute top quality medicine, offering freeze-dried medicine is a no-brainer for us.”

VoyageDenver: Check Out Josh Walker's Story
Josh was nominated by fellow community members to tell his story and share what we do at Lost Garden.
Lost Garden is officially a state-licensed natural medicine cultivation facility!
On November 24, 2025, Lost Garden Labs was officially licensed by the State of Colorado to produce natural medicine! This license marks the culmination of an intense period of preparation, dedication, research, and hard work. Throughout all of that time, we eagerly awaited the moment our medicine could be used by licensed facilitators across the state to aid in their important work in the healing space. Now, that moment is finally here!
