Dennis Ballesteros

Dennis was raised in the extraordinary landscape of the Galápagos Islands. As the son of a science teacher, his passion for science, ecology, natural history, and conservation was ignited at an early age. Since 2009, he has dedicated himself to sharing the unique wonders of this UNESCO World Heritage site.

As a Galápagos naturalist guide and avid wildlife photographer, Dennis combines his deep knowledge with an artistic eye, capturing the beauty and complexity of the natural world. Inspired by his upbringing in this ecological paradise and his role as a naturalist, he continually seeks new ways to expand his understanding and expertise. In addition to his professional pursuits, Dennis has a deep appreciation for Charles Darwin's contributions to science, often reflecting on his theories during fieldwork. His personal interests include stargazing, birdwatching, and snorkeling, which complement his expertise and enhance his understanding of the natural world.
