Brent began his professional journey teaching middle-school science in rural North Carolina. Since that time, Brent’s career has focused on science education, compassionate and inclusive leadership, and environmental stewardship. He holds master’s degrees in biological anthropology and not-for-profit management. Before joining the team at the Mountain Lion Foundation in 2022, Brent served as executive director at several not-for-profit organizations in Austin, Texas, and the San Juan Islands, Washington. Other experiences include playing in mediocre rock bands, management consulting, writing national science textbooks, and, as a young person, dreaming about someday seeing a mountain lion in the wild.

Paige grew up in Iowa with a love for the outdoors. She now lives in Chico, California, and is working towards her undergraduate degree in biology. During her studies, she has researched mammalian predators in the Big Chico Creek Ecological Reserve and worked for the California Department of Fish & Wildlife conducting bioacoustic and camera trapping surveys. She started volunteering with the MLF in 2020, and will now be advocating for mountain lion conservation as State Policy Associate.

Chelsea Robinson joined the Mountain Lion Foundation staff in 2020. She deftly handles myriad aspects of maintaining this organization and the services we provide and coordinates our Living with Lions webinars.

Prior to joining this team, she worked in administration with various nonprofits in and around Sacramento. She received her bachelor of science in business management — studying music, music business and culinary arts on her way to that degree.

In her spare time, she sings karaoke and DJs in Northern California, spends time with her lab mix dog, Jack, and photographs people and places.

Josh Rosenau

Director of Policy & Advocacy
916-442-2666 x107

Josh is a mammalogist who has worked to protect wild salmon and orcas, defend science educators against political pressure, and led efforts to push candidates to explain how science would inform them in Congress and the Oval Office. After graduating with a bachelors in Biology from the University of Chicago, he began a doctoral program at the University of Kansas, based in the Museum of Natural History. During his doctoral studies in Kansas, he changed directions from ecology and evolutionary biology to focus on science communication and science policy. With coalitions of clergy leaders, scientists, and parents, he led campaigns to defuse conflicts over the science lessons on topics like climate change and evolution. At the Mountain Lion Foundation, he is returning his focus to mammals, connecting and informing communities about their cougar neighbors, and helping to turn conversations from conflict to cooperation as we strive to Save America’s Lion.

Outside of work, Josh loves to explore wild places with his wife and two children. A lifelong hiker and birder, he has led Grand Canyon rafting trips and hikes, and since moving to Washington, has taken up kayaking and fly fishing.

Board of Directors

Bob McCoy

Sammamish, Washington

An interest in researching Puma concolor led Bob to the Mountain Lion Foundation. That was in 2009. Shortly thereafter, he successfully worked to stop the Washington Cougar Hounding Pilot Program, formed the Washington Cougar Coalition (WA Cougar), and become the Foundation’s Washington State field representative. Since then, Bob and volunteers successfully stopped several bills that would have harmed cougars. In 2013, Bob represented the Foundation on a panel at the 13th Mountain Lion Workshop in Utah. In 2015, Bob spurred WA Cougar to appeal the Washington Fish & Wildlife Commission’s failure to follow proper procedure in setting cougar hunting guidelines. Humane Society of the United States’ lawyers authored the administrative petition to the governor that achieved the first overturn and rollback of a citizens’ commission ruling in Washington state history. As part of a small coalition of groups and individuals, Bob helped in getting new commissioners appointed (2021 – 2023) that gives a majority vote to prioritize science over extractive “opportunity.” Bob frequently testifies for carnivores, and participates in outreach and education events. He is 100% committed to the Foundation’s mission. Bob has a Bachelor of Science degree and a Master of Business Administration.

Member of the Board of Directors since 2016.
