Who We Are

The work of Fossil Free PCUSA has rested on the shoulders and in the hands of hundreds of people. Below you'll meet the current Steering Committee of our work. Email us if you have questions or want to join our work. You can also stay connected in lots of ways.


Together we are for creation!
