Sarah Corcoran, Deputy Director

Growing up in a tiny rural community in the Poconos made for some interesting adventures outdoors at an early age. Sarah has taken that love of nature with her throughout the years. Over time she has worn many hats, including environmental education, outreach, and organizational roles. She is excited to continue working with folks in NEPA and other communities across the state to further educate Pennsylvanians on ways they can save their beautiful spaces.  Sarah loves re-selling vintage toys, playing in her garden with her chickens, geeking out to a good anime, video game, or book, and spending time with her family.

Chantal Mulenga, Associate Organizer

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 among 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 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 about how her 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.

Nate Reagle, Clean Energy Program Advocate

Nate is excited about his new role and hopes that he can have a significant positive impact regarding decarbonization and climate change. His background is in ecology with an emphasis on wildlife, fish, forestry, and insects. Due to this interest and his appreciation for biodiversity, Nate chose to enter the energy realm since climate change is a driver in biodiversity loss. Most recently before coming to the Sierra Club, he was an Energy Program Specialist with the Pennsylvania Department of Environmental Protection where he worked to improve equitable access to capital for energy efficiency and renewable energy projects. Nate currently reside in Mechanicsburg but is originally from Warren, PA. In his personal time, Nate advocates for insect biodiversity and conservation in Pennsylvania since no Commonwealth agency currently has jurisdiction over native terrestrial insects. He also enjoys reading and tending his garden and houseplants.

She is now serving as the Chapter's digital organizer, supporting staff and volunteers in communicating about our work. She is passionate about championing environmental causes, and can often be found outside photographing nature, hiking local trails, and doing yoga on a paddleboard.
