Costanza Di Prisco Director of Retreats & Immersions

Costanza began working with psychedelics more than 12 years ago, training with shamans and healers around the world. She is a Breathwork Coach and has studied to become a Psychedelic Practitioner, Somatic therapist and Bioneuroemotion therapist, a field that blends biology, neuroscience, epigenetics, NLP, and psychology. 

Her facilitation style combines ancient wisdom methods with cognitive therapeutic techniques from the West to produce powerful transformational experiences. She follows the tradition of the Shipibo from Peru in terms of shamanic techniques. Her goal is to serve as a bridge for people seeking to dive deep in their own journeys of self-discovery.

Costanza has been collaborating with Synthesis since 2021 as a Co-Lead Facilitator for the Retreats held in The Netherlands and as Guest Faculty for the Psychedelic Practitioner Training, more recently turning her focus to the development and delivery of the new Synthesis Immersion Experience.

Michaela Mairinger Director of Marketing

Michaela has dedicated the majority of her professional journey to fostering growth in startups. Prior to her association with the Synthesis Institute, she led the marketing initiatives at a digital mental health startup. Her educational credentials include a degree in Business and Marketing, as well as a Master's Degree in Marketing.

A personal experience with traumatic grief sparked a decade-long exploration into a variety of traditional and non-traditional healing methodologies. Michaela is particularly intrigued by the intersection of psychology and the symbolic language of archetypes. She has received training as a Gestalt Therapist, Drama and Art Therapist, Family Constellations Facilitator, SAT-certified Enneagram Practitioner, and Jungian Astrologer.

Michaela's first encounter with Ayahuasca in 2014 marked a significant turning point in her life, inspiring her to continue her exploration of various plant medicines ever since.


Andrew received his Bachelor of Science in Environmental Management and Protection from Cal Poly, San Luis Obispo. His academic training provided a foundation for understanding the relationship between human and ecological systems, although it was a consciousness expanding moment in 2013 that provoked a fully visceral and cathartic realization of the unsustainable systems of modernity. This existential awakening led him to seek alternative paths of living and being, and pinpointed the importance of a deep need for individual and collective transformation within consciousness.

His path naturally oriented towards practices within the yogic traditions, which ultimately led him to the Esalen Institute in Big Sur, CA where he devoted five years working and studying. Andrew ultimately found a love for psychedelic guiding and integration coaching, and he continues to find an ever-deepening well of compassion and awe for the complexities within our shared human experience.

His current inquiries include how to reorient our individual and collective values towards timeless wisdom, and how to personally and collectively remember the sacredness that is life.

Rev. Konrad Ryushin Marchaj Zen priest in the tradition of Zen Buddhism and a Dharma heir of the late John Daido Loori, Roshi

Ryushin Sensei was the abbot of Zen Mountain Monastery in the Catskill Mountains of New York. Born in Warsaw, Poland, he immigrated to the United States in 1967. He received a Bachelor of Arts degree in Anthropology from Yale University in 1976, and his medical degree from Albany Medical College in 1980. He worked first as a pediatrician in Portland, Maine, later serving in the US Navy as a physician for three years. He then returned to Albany for postgraduate training in psychiatry. After completing his residency, he served as medical director for a community psychiatric outreach program, the Mobile Crisis Team, which served Albany County’s disenfranchised and homeless population. He entered full-time residential training at the Monastery in 1992. In addition to his roles as the Monastery’s abbot and director of operations, he explored contemplative practices in higher education, collaborating with several liberal arts educators and administrators in the Northeast to look at ways for college students to engage in religious practice as part of their education. He has been practicing Buddhism since 1983. Since 2014, he has been rigorously exploring and training in ayahuasca ceremonies in various traditions, guided by several teachers. Drawing on his background as a physician and psychiatrist, Ryushin’s infectious interest and thorough training in the workings of the mind and compassionate expression of unconditional love, combined with his skill at translating complex concepts into the accessible, everyday language, characterize his unique teaching style.
