Extracting social and environmental justice from corporate boardrooms since 1995, Jennifer Krill joined Earthworks as the Executive Director in January 2010, where she leads the organization as it works to protect communities and the environment from the negative impacts of mining and fossil fuel extraction.
Jennifer’s personal mission is to end our dependence on destructive extractive industries by building a cleaner future based on sustainable and renewable alternatives. She co-founded and serves on the board of directors of Plug In America, which advocates for petroleum-free, pollution free electric vehicles. She also serves on the board of the Labor Network for Sustainability and the advisory committees of the Business Ethics Network and the Western Mining Action Network.
Jennifer holds a B.A. and a B.L.A. from Ball State University, and previously directed successful campaigns at Rainforest Action Network, where she helped protect old growth forests and prevent banks from financing climate change-causing industries. In 2014, she was inducted into the Women’s Hall of Fame of Alameda County, California for her work on behalf of the environment.
An avid traveler, Jennifer splits her time between Earthworks’ headquarters in Washington, D.C., and Earthworks’ field office in Berkeley, California, where she lives with her husband. Whenever she can, Jennifer escapes into the Sierra Nevada Mountains for skiing, paddling, and wilderness backpacking.

Melissa is an award-winning journalist and filmmaker who joined Earthworks as a Research & Policy Analyst in 2018. Her work includes the documentaries Triple Divide, TRIPLE DIVIDE [REDACTED] and the upcoming INVISIBLE HAND.
Truth, Transparency, and Efficiency compose a Holy Trinity that drives Melissa’s work, which includes a seven-year investigation of water contamination related to fracking development in Pennsylvania, published at PublicHerald.org and covered by national, state and local media.
In 2011, Melissa co-founded the investigative news nonprofit Public Herald, which unearthed and released thousands of citizen complaints related to oil and gas operations that were never made public by the state. Those complaints are now mapped and uploaded at PublicFiles.org/complaints. Public Herald’s 2016 analysis of drinking water complaints revealed official misconduct by state officials that leaves families without clean water for months or years. This prompted Public Herald to call for a criminal and civil investigation of the Pennsylvania Dept. of Environmental Protection.
At Earthworks, Melissa applies her research & writing skills to policies that protect communities and ecosystems. She is thrilled to join the ranks at Earthworks, which she considers the most grassroots – and most effective – ‘big green’ environmental organization in the United States.

Sharon is a 5th generation Texan who worked for the oil and gas industry in Ft. Worth, but was unaware of any environmental issues. After 12 years, she left the industry and bought 42 acres in Wise County adjacent to the LBJ National Grasslands. Unknown to her at the time was that George Mitchell was experimenting in Wise County to figure out how to produce oil and gas from shale. She had a ringside seat at the sneak preview called Fracking Impacts.
As she watched her air turn brown and, eventually, her water turn black she documented it all on her blog texassharon.com. Sharon and her son moved to Denton, Texas thinking the city would provide more protection. That irony still burns, but it brought her life’s work with Earthworks’ Oil & Gas Accountability Project in 2010.
Sharon has briefed NATO Parliamentary Assembly, EPA regulators and even former Administrator Gina McCarthy on the impacts of oil and gas extraction. In 2014, she became a certified optical gas imaging thermographer and now travels across the U.S. making visible the invisible methane pollution from oil and gas facilities.
