My Expertise

Shamanic Family Constellation

Read More

Shamanism naturally interweaves my practice of Systemic Constellations by B. Hellinger. The movements of the soul accept and benefit from wonderful allies such as rituals, journeys, music and nature.

Teacher Plants

Read More

Special funghi and plants can teach ourselves about ourselves better than anything or anyone else. They open the doors of perception and help us feel/see/smell/hear how precious all life is, how important and loveable we are – the way we are right now, and how we can contribute to our and everyone’s Wellbeing, Freedom and Joy.

Psychedelic-Assisted Psychotherapy

Read More

Being familiar with psychedelics through a long shamanic path and having trained in Spiritual Psychology and Systemic Constellations add up to my tool bag while I accompany people into healing and self-discovery.

Bhula ≈ Reading of Bones

Read More

Ancient sangoma practice. Umkhulu Gogo Sebastião clarifies your ancestors views about all aspects of your life. Wonderful tool specially if you are not sure on what to constellate.

Someone I didn’t know, while under effects of Ayahuasca, looked into my eyes and told me: Teach! I smiled and answered: You know! I have been a teacher for 10 years now and love it! That happened in 1996 and I still love to be a part of someone’s path to freedom, joy and respect for all our relations.
