Chantal Mulenga, Administrative Assistant

Chantal, an avid Mr.Rogers fan, is always looking for ways she can be a good neighbor. One of her life goals is to apply her rich experience with other cultures to raise awareness with youth on environmental issues that threaten equity and disempower low-income communities. Wife, dancer and enthusiast of all things discovery, Chantal has set out to answer one of Fred Rogers most burning questions, "What do you do with the mad that you feel?" With hungry eyes on the hard work of dedicated volunteers and staff, she thinks she has found the answer: organize, organize, organize!

Emily Abendroth, Program Manager - Philly Climate Works

Emily Abendroth grew up in a tiny town of 600 people located near the Canadian border in New York state. She spent almost twenty years teaching literature, poetry, and writing courses to undergraduate and graduate students across the Northeast and has her own committed writing/poetry practice. She has been involved in organizing against mass incarceration for decades and is a founding member of the Coalition to Abolish Death By Incarceration (CADBI) and LifeLines: Voices Against the Other Death Penalty. She has witnessed firsthand how our society's long-standing inequities -- such as the pervasive lack of healthcare access, structural racism, education disparities, mass incarceration, reproductive injustice, and a paucity of investment in public infrastructures -- are exacerbated and multiplied by the climate crisis within an extractive economy. For these reasons and more, she is especially excited for how her new position at Philly Climate Works allows her to collaborate with others in connecting the struggles for social and climate justice. She loves to swim, bike, grow veggies, watch esoteric cinema, peer at marine life with admiration and wonder, and constantly learn new things.

Rebecca Deegan, Outdoors For All Organizer

Rebecca grew up on Long Island, NY, where her childhood consisted of climbing trees, observing wildlife, and walking around town with her pet lizard on her head. She received a Wildlife Ecology & Conservation degree from the University of Delaware, and has pursued a lifetime passion of environmental education and climate justice. Philadelphia, which Rebecca calls home, is full of courageous activists and community organizers who inspire her daily. Every human has the fundamental right to safely access the outdoors, and Rebecca is honored to be part of the movement. Rebecca enjoys pointing at weird-looking bugs, cooking haphazardly, and trying to convince her cat and snake to love her.

Melissa Farr, Senior Distributed Organizer

Melissa grew up in Delaware County and holds a bachelor’s degree in history and master’s degree in social justice and community organizing. She gained organizing experience with the American Civil Liberties Union of Pennsylvania (ACLU-PA), serving as president of the South Central Chapter. Connecting with local communities about social justice issues deepened her understanding that one cannot struggle to improve the conditions of people’s lives in any one area of injustice without also looking at the forces that are shaping the environments in which they live. In her role as Senior Distributed Organizer, Melissa helps people develop the tools they need to advocate for the well-being of their communities. She loves her four cats, watching baseball, and visiting quirky indie bookstore, vinyl and vintage shops.

Tamia Sanders, Distributed Organizer

Tamia’s childhood memories are filled with moments of picking fruit on her great grandfather's farm, and spending hours in the local public library lost in a story.
