Jacob Stern, Pownal, Vice Chair
Since 2014, Jacob has been organizing and leading progressive grassroots campaigns at the state, regional, and local level. He's worked on political campaigns in Maine, Massachusetts, Michigan, and New Jersey. From 2017 until 2021 he served as a staff member at the Sierra Club Massachusetts Chapter, most recently as Deputy Director. In 2020, he co-founded the Sunrise Boston Political Team, fighting to elect climate champions in the Boston area. Jacob is thrilled to bring his experience as an organizer, activist, lobbyist, coalition-builder, and communications professional -- as well as his commitment to economic, racial, and climate justice to the Maine Chapter. A Maine native, Jacob is equally at home in both the state's granite mountains and on the cold waters off the coast. You'll find him one place or the other most weekends. Jacob currently lives in Pownal with his partner Madelyn and their dog Ziggy.

Ezra Sassaman
Ezra Sassaman, Bar Harbor, Secretary

Ezra Sassaman (he/him) is the Advocacy and Organizing Coordinator at Maine Youth for Climate Justice (MYCJ). Working at MYCJ has furthered his knowledge of the inextricable links between climate justice and social justice. Ezra recognizes protecting the climate must also mean overcoming unjust and unsustainable hierarchies such as colonization and capitalism.

In his MYCJ role, Ezra has supported MainePERS divestment implementation, the Pine Tree Amendment, tribal sovereignty legislation, and funding climate education in public schools. He is currently helping organize MYCJ’s offshore wind speaker series, where experts in the field share their perspectives and answer youth-led questions about wind power in the Gulf of Maine.

At the local level, Ezra serves on Bar Harbor’s Warrant Committee, which approves the annual town budget and makes voting recommendations for land use ordinance changes and citizen’s petitions.

Ezra believes it is past time for everyday people to take back the power that has been concentrated for far too long in the hands of the few. We know the status quo is not working, so let’s be uncompromising and bold about the future we know we can create!

Becky Bartovics, North Haven
Becky is a grandmother, farmer/gardener, networker, community and environmental activist. Working in alternative energy and water conservation, and as a teacher, she has long been involved in promoting energy and water conservation, in Massachusetts as well as Maine. Formerly President of Penobscot Bay Alliance, she became involved with Sierra Club Maine through the Sears Island Planning Initiative during the Baldacci Administration. Ever more concerned about her grandchildrens’ future, she has become increasingly involved in climate change activism and protecting biodiversity. Serving on the Sierra Club Council of Club Leaders, Legislative, Climate Action, Political and Advancement Teams, she has been involved in most aspects of the Chapter and its growth. 
At home, she has participated in the Comprehensive Planning Committee for North Haven and has been an elected member of the North Haven Planning Board and the North Haven Budget Committee. Founding member of a new group on North Haven to address significant invasive intrusion, she has been experimenting on her farm with livestock, primarily eradication followed by cover cropping. Collecting native seeds and starting a native plant nursery, the goal is to create a biodiversity found on this island only during the time of Indigenous habitation.
When not on zoom or working on Sierra Club Maine programs, she can be found midwifing a flock of dual breed sheep, broad forking the market garden, laughing at chicken antics or pulling grandchildren in the garden cart. She firmly believes that activism is empowering and inspiring.

Scott Cuddy
Scott Cuddy, Winterport

Scott Cuddy joined Sierra Club Maine's Executive Committee in 2024. He ran because, "I’ve had to explain to my two boys why the world they're going to inherit will be so different, and more difficult to live in, than the one I grew up in. While I have the time, talent, and strength I will do everything I can to solve this problem. Climate Change is the single largest threat to us and the Earth, and we need to fight it with that level of urgency."

Scott was born and raised in Winterport. He eventually bought the house he grew up in from his mother, who then built a house next door and helps Scott and his sons every day. He's been a union electrician with IBEW 1253 since 2005. His union affiliation and service on the RSU 22 School Board made him realize many of the changes he wanted would need to be made in Augusta. Scott ran for State Representative, winning in 2018 and then again in 2020. He was endorsed by SCM in 2020. He chose not to run for re-election in 2022 because he could not financially afford to serve.

Scott has served on the board of the Maine Center for Economic Policy (MECEP), Food AND Medicine, RSU 22, and the Eastern Maine Labor Council. He was recently re-elected to the RSU 22 School Board and appointed to serve on the Board of Occupational Safety and Health.

Scott shares, "I hope to be an integral part of continuing the kind of cooperation between organized labor and the environmental community that creates an unstoppable force for the good of the state. That collaboration recently won incredible legislation to move floating Offshore Wind forward in Maine, and there is so much more that we can do!"

John Fitzgerald, Sedgwick

John is an attorney and advocate, working primarily with non-profit conservation groups and think tanks.

John has served on Sierra Club Maine’s Executive and Political Committees since early 2022 and co-chairs the Legislative Committee. He is a Council of Club Leaders Alternate, and serves on the Conservation Policy Advisory Committee of National Sierra Club.

A part time consultant, he is the legal advisor to the Climate Intervention Environmental Impact Fund, a new group that will help scientists prepare environmental assessments in advance of field tests of safe, controllable climate interventions such as methods of destroying or sequestering greenhouse gasses. He served from Autumn 2020 to August 2023 as Legal and Government Relations Counsel to Methane Action which
merged with Spark Climate Solutions in 2023.

He is Vice President of the Board of the Climate Protection and Restoration Initiative founded by Climate Scientist Jim Hansen and his Policy Advisor, Dan Galpern and allies.  John is also a member of the Board of the Environmental Investigation Agency, an NGO based in the US and the UK that documents and works to end environmental crimes world-wide.

As chief counsel at Defenders of Wildlife from 1984-94, John was a leader in the Endangered Species Coalition, crafting strengthening amendments enacted in 1988, and returned again to the Coalition when he was Policy Director of the Society for Conservation Biology from 2007 to 2013. At Defenders, he prepared and coordinated numerous lawsuits including the one that ended United States agencies’ assistance in building the Three Gorges Dam in China. He helped strengthen the Marine Mammal Protection Act, served on the Northern Right Whale Recovery Team and drafted the original dolphin-safe tuna labeling law. He also drafted the amendment to the Lacey Act that banned imports and interstate trade in illegally harvested wood. John helped to strengthen oil spill legislation in the United States and sanctions against nations that undermine international conservation agreements.  He helped to negotiate the Convention on Biological Diversity, and helped to prevent several attempts to weaken the treaty as it was being drafted and at the United Nations’ Conference on Environment and Development in Rio in 1992.  Before joining Defenders he served as a legislative aide and subcommittee counsel in the U.S. House of Representatives from January 1979 to September 1984 helping to staff the Solar Energy Caucus, to write a strong Superfund law and close loopholes in the Ethics in Government Act.  

His methods for ranking nations’ stewardship of natural and human resources helped shape a foreign assistance initiative, known as the Millennium Challenge Corporation while he was in the Policy Bureau at USAID. He was featured as an Earth Champion by Public Employees for Environmental Responsibility who represented him in a successful whistleblower challenge of the Bush Administration’s elimination of his position at USAID for briefing Speaker Nancy Pelosi and others on their Treasury Department’s continuing violations of the Pelosi Amendment regarding environmental impact statements for World Bank projects. He worked with Speaker Pelosi, Senator Leahy and others in Congress to strengthen the law that she originally championed in response to those violations.

John received the 2012 Brock Evans Award presented by the Endangered Species Coalition (ESC) for his long-standing work to protect endangered species and the Distinguished Service Award from his college preparatory school alma mater, Northfield Mount Hermon School, for his service to the public.

Isidora Liliana Muñoz Segovia
Isidora Liliana Muñoz Segovia, Bar Harbor

Isidora is a multidisciplinary Chilean and Spanish environmental activist. She has been involved in environmental activism for 8 years and during the last 5 years she has been studying environmental politics among other focus areas like indigenous knowledge and sustainable agriculture as a Human Ecologist. Her work on environmental politics brought her to attend COP25 in Madrid in 2020 and COP26 in Edinburgh in 2021. At these UN Conferences of the Parties she followed indigenous and agricultural negotiations as well as assisted different groups with civil actions. During the COP in Scotland she also supported Demand Climate Justice as a spokesperson at the Presidential Stocktaking Plenary making a statement demanding tangible actions on real zero and accountability for the nations that have historically contributed the most to our current climate crisis. 

After her experiences in the international realm of environmental politics and climate change, she decided that she wanted to put her energy to support grassroots work. In 2020 Isidora was part of the Agroecology Lab at the Universidad de la Frontera in Chile where she researched the overlap between western science and Mapuche indigenous practices while also learning about indigenous environmental activism. This experience broadened her scope when thinking about how we can incorporate different ways of seeing the world. As a part of her senior thesis in 2022 Isidora developed a movement practice where she wove together different ontologies from the south like indigenous Mapuche Kimvn from Chile and the Sentipensar philosophy from Colombian coastal traditional knowledge with western modern science communication to encourage education and action regarding climate change. This practice is MOASSE (Movement As a Seed for Change) and it was first brought to life at COP26 in Edinburg with more than 200 participants. Recently MOASSE has evolved to focus on Maine coastal communities' relationship with resilience. In March of 2023 MOASSE was part of the Cambalache International Conference of Autonomies in Practice in San Cristobal de las Casas, Mexico, where Isidora and her collaborator presented their theory and praxis in the context of anti-capitalist/anti-colonial arts. 

She is excited to continue exploring the potential to create bridges among different communities when it comes to not only to imagine but to embrace a thriving future for all. She is currently one of the Rural Youth Organizers with JustME for JustUS where she is focusing her work to uplift coastal communities and in particular young fishing communities’ vision on climate actions in Maine. She is also committed to strengthening partnerships among environmental groups and the Wabanaki tribes in Maine. She believes that only when we allow space for people to express and listen to themselves we can start feeling the strength of our communities. 

Isidora has also been part of the IV Latin American Congress of Political Ecology in 2022 as a panelist on “Human Ecology inside Political Ecology”. She was also a guest speaker at Colby College presenting “Exploring Ontologies in our Current Climate: Stories from Chile, Scotland, and Maine” as a part of the World Beyond Human course. Isidora was part of the panel on Women & Gender Expansive Roundtable Discussion hosted by Maine Youth for Climate Justice in 2023. In 2022 she was also nominated to the Brookies Award for her environmental leadership.
