Antonio Tadeu de Oliveira—“Tadeu” to most—started his career in travel as a flight attendant, spending four years working on airplanes before realizing his real interest was on the ground, in wild places. In 2013, he left commercial aviation behind and began guiding tours, using his fluency in both Portuguese and English to connect with travelers from around the world.

Tadeu went on to complete a wide range of training programs, gaining certification as a professional guide with a strong focus on Brazil’s diverse landscapes. Over the years, he has become especially knowledgeable about the state of Mato Grosso, including the Pantanal—the largest tropical wetland in the world—and other key destinations in South America. He’s known for his deep regional knowledge, practical expertise and ability to read the landscape, whether it’s spotting a hyacinth macaw in a palm grove or explaining the ecology of a flooded plain.

Today, Tadeu lives with his wife and three daughters in Chapada dos Guimaraes, a small town perched on the edge of a national park known for its cliffs, waterfalls and sweeping views of the surrounding cerrado. When he’s not guiding, he’s often exploring the area with his family or keeping up with the latest conservation news from the region.

Tadeu brings more than a decade of field experience to his work as a guide. He’s calm under pressure, a clear communicator and a steady presence in the field. Whether leading a hike, managing logistics or sharing local history, he’s focused on giving guests an authentic and memorable experience in some of Brazil’s most remarkable wild places.
