Jeffo Marquez

Expedition Leader Jeffo MarquezJeffo Marquez was born and raised in the Galapagos Islands. A native “Isleño” who has moved about the archipelago since childhood, he was inspired by his father’s job as a Galapagos herpetologist. Growing up, Jeffo gained hands-on inspiration through many opportunities to accompany his father on field expeditions studying Galapagos reptiles. Today, as a Nat Hab Expedition Leader, Jeffo is passionate about the art of interpretation and sharing his homeland with our guests.

Jeffo began his professional life as a restaurant administrator before starting a second career in environmental management. The focus of his studies included management of protected areas and wildlife, and tropical dendrology in Costa Rica. He is a standing member of the National Association for Interpretation as an international interpretive guide. His passion for the Galapagos landscape is on display every time he joins our guests in the field to talk about wildlife and nature. His mission is to make people fall as deeply in love with the Galapagos Islands’ natural history as he has—and the pathway to that goal is knowledge and education.

Throughout his career as a Galapagos naturalist, Jeffo has also honed his skills as a professional photography instructor. In addition to the Galapagos, he has also guided in Costa Rica and the Upper Amazon, with a focus on locations where wildlife is on display in particular splendor.

Jeffo was a delight and full of interesting stories, and he had a depth of knowledge that he always enjoyed sharing with us.
