Marc lived and worked in Galapagos from 1998 to 2002, where he helped develop and launch the Isabela Island goat eradiation project with the Galapagos National Park Service and the Charles Darwin Foundation. His first son was born in Ecuador and spent the first three years of his life in the islands. After Marc and his family left Ecuador, they started a very small business, Cultural and Natural Heritage Tours (CNH Tours), which focuses exclusively on Galapagos. In 2003, Marc was hired by UNESCO's World Heritage Centre in Paris, focusing on natural heritage sites in the Caribbean and in Latin America, including Galapagos. This gave him privileged access to decision-makers in Ecuador (he once had a private meeting with the president) in regards to Galapagos conservation issues. During those years, Marc's wife Heather worked on the business to the point where, in 2015, it was possible for Marc to leave UNESCO and join her full time at CNH Tours. Last year, he was voted in as a member of the governing council of the Charles Darwin Foundation and he retain close ties with many people in the islands. Marc lives in Ottawa.
