Board of Trustees

We are fortunate to have a dedicated Board of Trustees with a diverse skill set and a commitment to sustainable living.

 

Eve Coulson, President

In Princeton, Eve serves on the Princeton Zoning board and is active at the Princeton Jewish Center. She sees neighborhood building as an underestimated yet very powerful way to increase sustainable practices in daily life. She always takes the stairs—and she has discovered that sometimes the smallest things convey a big message. She carries a spork with her everywhere, which has not only saved the lives of countless plastic spoons and forks but sparked many conversations (“what IS that thing?”), about how one’s habits can have cumulative positive impacts.

Alexandra Bar-Cohen, Vice-President

Locally, Alexandra served in AmeriCorps for the Princeton School Gardens Cooperative helping the garden club take root at Littlebrook School, and has demonstrated a continued passion about instituting low-waste measures to “green” events. She loves helping Princetonians discover how easy it is to be more sustainable—from chatting with people about thinking before they toss to organizing a sustainable fashion show at GreenFest. Alexandra recently retrofitted her 1932 home with a geothermal heating and cooling system, and is grateful that her EV means she’ll never have to pump gas again.
