Sergio Cahueque joined the team after graduating from College of the Atlantic in the spring of 2017, where he focused his studies on Environmental Sciences and Social Studies. At college Sergio had the opportunity to engage with Earth in Brackets, a student-led organization that explores the overlaps between environmental justice and social justice. During this time Sergio attended meetings under the United Nation Framework Convention on Climate Change, where he collaborated with grassroots and policy-led organizations working under the climate justice movement. After his experience with international environmental policy and inspired by the grassroots and popular movements in Latin America, Sergio decided to go back to Guatemala (his home country) and conduct ethnographic research for his undergraduate thesis. Sergio spent three months conducting research in La Puya, a peaceful resistance movement made by communities in San Jose del Golfo and San Pedro Ayampuc. These communities are in resistance against a U.S.-sponsored gold mine that poses a threat to their health by poisoning with arsenic the already scarce water. As an organizer Sergio is committed to creating spaces and providing tools for people to speak up and take action against social and environmental injustices. Sergio believes that to foster a healthy environment and a healthy and honest democracy we need to work from the bottom-up.

Adam worked for eleven years as an organic vegetable and grain farmer as the co-owner/manager of Songbird Farm in Unity, Maine. The farm focused on local markets, heritage grains and community involvement as pathways to strengthen a sense of place and history. Nordell feels that the local food movement gives people a direct, tangible stake in the health of their local ecosystems. In late 2021, Adam and his wife Johanna discovered severe PFAS chemical contamination of their land, drinking & irrigation water and their bodies. The discovery led to an immediate, voluntary closure of farm operations and launched Adam into an advocacy role, fighting for impacted communities and against continued contamination. He is excited to continue this work as part of the Defend Our Health team, where he will be organizing with people impacted by PFAS and advocating for a responsible, impactful allocation of state resources to support those communities. Adam has a BA in Human Ecology from College of the Atlantic.
