Linda Sell - Co-Founder, Advisor

Linda is a Co-Founder and former Board Member of the environmental non-profit Bay Area for Clean Environment which has been instrumental in radically reducing emissions of local toxic pollutants. In recent years, she has worked with volunteers across the state collecting thousands of signatures for petitions and gathering organizational endorsements in support of state legislation to reduce carbon emissions and combat climate change. Over the last decade, she has served on an educational foundation and in leadership positions on several steering/campaign committees. Those efforts have resulted in fundraising campaigns and the passage of local funding measures that have raised millions for our local schools which are being invested into instructional and enrichment programs.

Linda is currently a member of the City Council for the City of Sunnyvale.

She also co-lead's the Sierra Club Loma Prieta Chapter’s Climate Action Leadership Team. Kristel enjoys hiking and biking in the fantastic protected open spaces we have within a short (electric vehicle) drive.

Erin Zimmerman - advisor

Erin Zimmerman has been studying the political impacts of environmental change for over a decade. She received her Ph.D. in Political Science from the University of Adelaide, Australia, in 2013. Her doctoral dissertation examined the influence of non-traditional security issues, such as climate change, on regional governing institutions in Asia. Her master’s thesis, completed in 2010, examined the negative impact of environmentally induced migration on state stability.

As an environmental advocate Erin has been involved with many organizations in Australia, Switzerland and the United States of America. Most recently, she was trained as a Climate Reality Leader in 2019 by the Climate Reality Project.

David Poeschel - advisor

Dave began pursuing his passion as a “self taught ecologist” as a child in the vacant lots and drainage ditches near the Sacramento home where he grew up.  He worked as a software engineer before retiring to focus on environmental conservation.  His education continued as a volunteer and campaign activist with CNPS, SCVAS, Sierra Club Loma Prieta Chapter and serving on several governmental committees providing him with many years of experience, particularly on City of San Jose land use and environmental policies.

Dave leads native plant restoration efforts in Guadalupe Oak Grove Park, possibly the last remnant of valley floor oak woodland in Silicon Valley.  He also shares his environmental knowledge as a docent for the Santa Clara Valley Open Space Authority and at various park activities.  He has also enjoyed volunteering as a math and reading tutor for elementary school children.
