  • Gaby Bohorquez

    Expedition Leader
    Gaby was born and raised in Guayaquil, Ecuador. Her first job in the Galapagos was on board a 90-passenger cruise ship as the cruise director’s assistant, and she fell under the spell of the Enchanted Isles. She returned to Guayaquil to study at the Espiritu Santo Technological University to obtain a degree in Tourism Management. Her fascination for the islands was still strong so, after finishing her studies, Gaby took the opportunity to join the Naturalist Guide’s course, jointly organized by the Galapagos National Park Service and the Charles Darwin Research Station. That was back in 1992, and she has been a naturalist since, keeping her deep love and passion for the islands during all these years.
