A 501(c)3 nonprofit organization founded in 2013. We are a highly specialized international team with decades of experience working with indigenous peoples in the Amazon.

Through our collaboration with indigenous communities, we build projects that promote self-determination, advance scientific research, preserve ancient knowledge, and protect ancestral lands.

We document, learn, and participate in programs to foster cross-cultural awareness and teach the world the importance of preserving indigenous cultures and methods of sustainability.


They are an indigenous people that subsists mostly by hunting-gathering and simple horticulture. Their territory spans across the southeastern Venezuelan and northwestern Brazilian border within the Amazon rainforest. Historically, they have been known for maintaining their traditional way of life, but more recently, their microbiome linked to their health status is earning them increasing popularity. Many experts say that there are villages that yet to be contacted.


Since sustained Western contact first began in the 1950s, the Yanomami have been confronting the spread of novel infections diseases, invasion of illegal of gold miners, and engagement with political and economic policies that affect their livelihood.
The Yanomami benefactors of this project live in a region known as the Upper Orinoco of Venezuela. These communities are at the interface of practicing traditional customs while engaging with outside agencies to cope and learn how to navigate their changing society. The Yanomami critically need support to protect their way of life and maintain the health and welfare of the more vulnerable, less frequently contacted communities of the interior.


The outcome of this expedition will contribute to the following



Supporting Yanomami communities on the front lines of disease outbreaks is critical if we are to protect the more vulnerable and isolated communities of the interior.
Our Impact

  • Enhance monitoring of Yanomami health situations health leading to improved disease surveillance and medical response times.

  • Help limit the spread of infectious through culturally sensitive public health training and workshop in disease recognition and prevention 

  • Facilitate reliable emergency transportation of patients and medical personnel to outpatient clinics.



Human microbiome research is critical for understanding how our microbes affect human health and disease. As people of urban, industrialized societies are rapidly losing their microbial diversity, the Yanomami continue to maintain one of the most biodiverse microbiomes in the world. As a result, chronic diseases of inflammation and autoimmunity are virtually absent.
Our impact

  • Increase our understanding of Yanomami health and food systems as it relates to their gut and skin microbes.

  • Advance important research that provides a benefit to all of humanity.

  • Set important precedence in ethical research by including the Yanomami people as research partners and active participants.

  • Raise global awareness on the importance of protecting the rainforest and the Yanomami microbes.



Yanomami Intercultural and Bilingual Schools integrate traditional culture and belief systems while providing the tools to achieve self-representation and self-determination on the world stage.
Our Impact

  • Advance the Yanomami people's right to have access to intercultural education.

  • Increase administrative efficacy by facilitating reliable access to educational information and networking with local and national institutions.

  • Facilitate important unique dialogue and exchange between Yanomami communities of Venezuela and Brazil, and the rest of the world​.

  • Provide reliable and clean transportation for Yanomami students and teachers.

Environmental Stewardship

Our goal is to implement the best innovative technology to support Yanomami programs. With advanced zero-emissions technology powered by renewable solar energy, we become stewards and allies of the Amazon.
Our Impact

  • Decrease dependency on gasoline and other fossil fuels.

  • Decrease the output of harmful fumes and pollution.

  • Facilitate future research and medical programs by sharing resources with the Yanomami people and other support groups.

  • Create an atmosphere of collaboration, trust, and efficiency as we work together to protect the sustainability, health, and welfare of the Yanomami
