Our Team

Our Team is Our Most Valuable Asset

Integration is the most important phase of any medicine experience. It can be understood as the master key that catalyzes maximum transformation within an individual’s experience. To get the most of a 5-MeO-DMT experience, integration is non-negotiable. The process itself is hard work. It can bring to the surface challenging realizations, and recognition of behavior and thought patterns that no longer serve your purpose. This is why we take such pride in the members of our team.

Joël Brierre

Founder & CEO of Kaivalya Kollectiv and President of Tandava Retreats

Joël Brierre (aka: Joël the entheogenic yogi) is a pioneer in the modern psychedelic movement, and has years of experience in the realm of 5-MeO-DMT and the Bufo Alvarius toad. His unique approach of applying classical non-dual yogic philosophy for both the preparation and integration from the entheogenic experience gained attention from around the world at the first World Bufo Alvarius Congress (WBAC) in 2018 and continues to shift the landscape of psychedelic use.

Joël leverages over a decade of retreat experience to curate a container that is designed to facilitate lasting change for participants. Drawing from a combination of timeless Eastern and contemporary Western integrative practices, Joël has ensured that Tandava Retreats give participants a container in which to safely unfold, explore the depths of their inner world, address underlying trauma, undergo cathartic release, and have the support system in place to help draw life-changing meaning from the experience.

With a heavy focus on integration and aftercare, Tandava Retreats give participants the means to create lasting change and find deeper states of peace than they ever thought possible.

Joël’s work at Tandava Retreats is consistently raising the bar for psychedelic and wellness offerings, working in breathtakingly beautiful settings around the world, and led by highly learned teachers and practitioners. Safety is Joël’s number one priority, followed closely by ensuring a warm and welcoming container that is both nurturing and expansive for each participant.

Victoria Wueschner

Victoria Wueschner

Head of Education

Victoria Wueschner’s introduction to the world of healing was through plant medicine. She has always loved jumping into the deep end, which is why she attended seven consecutive ayahuasca ceremonies in 2012 and realized she had found her path.

Victoria explored the world, working with different psychedelic plant medicines with indigenous and modern teachers. In 2016, she completed her Yoga teacher training in Bali, along with her levels one and two Reiki certification before returning home to Vancouver Island to share these gifts and deepen her fascination with plant medicines.

After taking time to honor her own process and growth, Victoria stepped into the role of medicine practitioner with the goal of helping others on their own unique journeys. In early 2019 she completed her Kambo training and certification through IAKP in Thailand.

Victoria proceeded to complete her training with the powerful medicine of the Bufo Alvarius toad, said to be the most powerful psychoactive experience known to man. Deeply moved by the force of this medicine, she immersed herself in the toad community, learning all she could in order to best serve those whose journey brought them to experience 5-MeO-DMT.

Victoria is President of the education platform F.I.V.E., a Head Retreat Leader for Tandava Retreats, as well as Head of Education for Kaivalya Kollectiv. With a focus on using the hero’s journey as a lens, Victoria assists participants to explore their own innermost workings and helps them unravel the very thought processes that have caused turbulence to their minds so they can enjoy a more peaceful state of mind.

Otto Maier

Otto Maier

Psychedelic Integration Coach, Kambo Practitioner, Breath-work & Meditation Instructor

Otto is a certified and practicing Psychedelic Integration Guide, Kambo Practitioner, Breathwork facilitator, Psychedelic educator with Psychedelic School, and a spiritual and emotional well being teacher. His personal spiritual path has led him from personal tragedy and a mental health crisis to spending months studying meditation at Ashrams in northern India, experiencing master plant diets in the Peruvian jungle, studying psychedelic integration, Jungian psychology and transformational recovery. Finding inspiration and resonance from the teachings of depth psychology, Jiddu Krishnamturi, abstract expressionism, and plant medicine.

Through his studies and trans-personal experiences, it became apparent that these series of “tragedies” in his life were actually the hallmarks of an alchemical process of awakening into a deeper, more meaningful and soulful life. It is his personal conviction that our most direct source of meaning and communion with our essence and vitality is to uncover and connect to the language of this alchemical process – a language that moves through us.

The main focus of his work is assisting others is to bridge the gap between their plant medicine/spiritual experiences and their everyday lives. He enjoys riding motorcycles, reading Jungian psychology, daydreaming, drinking far too much coffee, crying, poetry, sharing music, ideas, minimalism, nomadic living, long-boarding, and dark humor.

Many individuals work with Colette to learn Shamanic practices, with and without sacred medicines, to support their neurological systems, heal trauma triggers, change unhealthy thought patterns, support neurodivergent stress in a capitalist world, and find empowerment in being able to control their own self directed brain change.

Colette trains virtually all her coaching clients in self-directed neuroplasticity techniques that help redirect unhealthy or unwanted patterns of belief or cognition towards better ones, and arms her clients with their own ability to support positive change in their daily lives.

Alberto Yarleke playing flute

Alberto Yarleke

Born in the late 60`s in a Native Q`echua Community on the eastern slope of the Andes, Vilcabamba, Ayacucho – Peru.

Coming directly from a native biological root has had a very important impact on his life, defining and linking him directly with one of the most ancestral and recognized practices within the cultural platform of his community.

Alberto had many extrasensory experiences when he was still a minor and later in adolescence, he became aware of these natural aptitudes and began to develop them gradually. So it was that from his early adulthood he became an active promoter of health.

In the previous period (as an apprentice) during his years of research and practice, he had the opportunity to connect with some Native traditions in the south and north of the continent. Besides nurturing, amplifying and refining his extrasensory aptitude, those trips also gave him the opportunity to gather the material and empirical support required to create an anthology of work containing the essential fundamentals coming directly from the knowledge and experience of various native masters. These include the management, the use of the benefits of the “power plants”, the extrasensory aspect of shamanism, and the knowledge associated with neuroscience and transpersonal psychology for application in therapeutic treatments.

To date Alberto has 25+ years of solid experience in this medical aspect of shamanism.

Based on all that experience, he has elaborated a characteristic system of work where he links the influential impact of the energetic effect with the benefits of the deep understanding of transpersonal psychology and the basic elements associated with science.
Investigations, Practices and Initiations:

Anthropology of Being – A.G.E.A.C.A.C – Peru.
Internship in Veda Temple – Colombia.
National Institute of Transpersonal Psychology – Mexico.
Initiated in the Wixàrika Community Tradition – Mexico.
