About Us


Onçafari consists of an interdisciplinary team of biologists, veterinarians, field guides, psychologist, and even a former racing driver.

Meet some of our amazing team members, who are all passionate about what they do.


Mario Haberfeld


Mario was born in Sao Paulo, Brazil, and has had two abiding passions since childhood: racing cars and wildlife. After a long career of nearly 20 years in motorsport, with stints in Formula 1 and Formula Indy, he decided to dedicate himself entirely to wildlife conservation. He has traveled to various parts of the world in order to visit several animal conservation projects involving gorillas, tigers, polar bears, pandas, leopards, lions and more. Mario decided to establish Onçafari in order to conserve Brazil's biodiversity, and to assist in the development of local communities through ecotourism and science.

Leonardo Gomes


Leonardo is a psychologist who graduated from the Federal University of Rio de Janeiro. Leonardo has operated for over ten years in the Third Sector, which deals specifically with the issues of local development, employment and education. He also has extensive experience in the fields of management and product development. As director of Onçafari, his focus is on design and project management, as well as institutional relationships. He is also on the team of SOS Pantanal, which oversees a project of international cooperation.

Simon Bellingham


Simon was born in Zimbabwe, where, as a child, he became fascinated by nature. He started his career as a professional wildlife guide in South Africa, working for several major groups of small hotels that utilize ecotourism as a method of conservation. He has made significant progress in his career and now holds the most advanced certification in his profession in South Africa. After meeting Mario, they developed a plan together to promote ecotourism in Brazil. After several visits to the Pantanal, it became clear that for any plan to work it would be crucial to include jaguars.
