Who We Are

Steering Committee

Stephanie Marshall

Stephanie is a native of NH who now lives in Exeter. She has worked with 350NH for 5 years. After seeing Bill McKibben speak she was grabbed with the realization that she couldn’t go on living her life as “business as usual” without being involved in climate justice work.  Stephanie embraces the intersectional focus of 350NH’s work, based on her career as a social worker and business consultant. She loves working with the activist youth in the movement who are very tolerant of her challenges with technology and is always inspired by their knowledge, commitment, and courage.

Sam Tardiff

Sam Tardiff of Concord is an undergraduate student at the University of New Hampshire where he studies Environmental Conservation and Sustainability. Before UNH he attended the University of Mississippi, where he promoted climate action by organizing students for canvassing efforts during the 2016 presidential race. Sam was first introduced to 350NH’s offshore wind campaign in 2017 and since then has spent time helping the team organize events and build outreach through social media. He wants to help build the grassroots coalition necessary to create change in New Hampshire so that the mountains, lakes, rivers, and coastline remain healthy and beautiful for years to come.

Elizabeth Lamy-Harris

Elizabeth is a lifetime environmental advocate who lives in Hopkington New Hampshire.  As an elementary teacher she taught as much about environmental stewardship in her classroom as she could. In 2008, she was moved by the science brought to light by Bill McKibben and his colleagues at 350.org.  Elizabth stepped forward in 2012 with a handful of others to form the 350NH.  Illness kept her away for a few years, but now she is back, hoping to do her part to promote the Offshore Wind and stop future fossil infrastructure. She has worked toward bringing intergenerational and interracial storytelling trainings across the state.  Through this project, 350NH hopes to find and create links between ourselves to build community, increase knowledge of individual and shared values, help make sense of the issues we face in this moment, and explore the power of shared stories to affect change.

Doug Bogen

Doug Bogen has been an environmental organizer and advocates for almost four decades, focusing on grassroots, citizen advocacy efforts and community-based solutions to our most challenging environmental issues. He is currently director of Seacoast Anti-Pollution League in Exeter, focused on opposing the re-licensing of the Seabrook nuclear power plant, promoting renewable power alternatives and watch-dogging the clean up of Superfund toxic waste sites at the Portsmouth Naval Shipyard. He previously worked with Clean Water Action’s NH program from 1991 to 2009, serving as state program director for most of that time. He worked on issues of combating climate disruption, toxic contamination, drinking water protection, cleaning up the state’s old fossil-fueled power plants and coastal water quality. He is also a founding member of Seacoast Peace Response and the Portsmouth-Severodvinsk Connection, as well as a member of the Barrington Conservation Commission. He lives in Barrington and has been a resident of New Hampshire’s Seacoast region for over three decades. Bogen holds a masters degree in Science and Environmental Education from Cornell University.

Ken Grossman

Ken Grossman is a retired educator living in Barrington NH who has been a member of 350NH since its formation.  He has had a range of teaching experience including college level philosophy, middle school science, and graduate level teacher education.  Ken holds an EdD degree from the University of Massachusetts. In 2012 Ken was elected as a New Hampshire State Representative. He has also served as a member of the Barrington Conservation Commission.  Ken likes to be out in the woods, on foot or in a canoe. He plays a little ukulele and has been sometimes seen performing at open mics with life partner and wife, Holly.



Griffin Sinclair-Wingate
Griffin has been organizing around justice issues since 2011. In high school he organized summits for students from around the state to talk about challenging the culture of apathy in their schools. During his time at UNH, in addition to studying Environmental Resource Economics and Political Science, Griffin worked on a number of student organizing initiatives including fossil fuel divestment campaign and campaign finance reform.  Before starting with 350NH Griffin worked with 350 Action pushing 2016 presidential candidates to take strong policy stances around climate change. Now in his role as Volunteers Coordinator he works with community leaders to resist fossil fuel projects like the granite bridge pipeline, promote renewable energy opportunities like offshore wind, and build community through educational events and trainings.
Lila Kohrman-Glaser

Lila Kohrman-Glaser received a degree in biopsychology from Tufts University in 2015 where she was a founding member of Tufts Climate Action and a lead organizer for fossil fuel divestment.  She spent 2 years after college living and traveling in South America where she worked as a community organizer and volunteer coordinator for two non profit organizations in the faith community.  She brings 6 years of community organizing in the climate movement and faith communities to 350 New Hampshire, and specializes in grassroots fundraising and volunteer management. Lila can be found hiking, biking, swimming, running, and skiing around the great outdoors when she is not at work organizing for a radical shift in climate and energy policy in NH.

Clarice Perryman

During my senior year a student had written on the window of a room in the science library “Why can’t scientists be activists?”. This question has stuck with me ever since.

As a graduate student studying the effects of warming on arctic ecosystems I know the science on climate is clear and a just transition to clean energy must be a priority for the state of New Hampshire. After the last election I felt a call to put my knowledge and passion for climate science into action, and shortly thereafter found the work of 350 New Hampshire. Right away, I got the chance to help plan and facilitate the latest strategy session and am excited to take action to see how I can help energize others to grow the movement for climate justice stronger than ever in the new year.

Nick Dundorf

Earlier this year, I participated in and spoke at an Offshore Wind rally at the State House. This gathering of people wasn’t just a show of power and support for renewable energy. It was a community.

As a high schooler growing up in an America where science is ignored and partisan divides are as strong as ever, this community gives me strength. It reminds me that I am not alone. I’m not alone when I say “Something has gone horribly wrong”. When I give time, energy, and support to 350NH, I get it back tenfold

350.org vs 350NH

350NH is financially and legally independent from 350.org.  We share a theory of change, our brand, and occasionally work together for days of action.
