Working for Natural Resources Defense Council, Sierra Club, and Greater Yellowstone Coalition, and Center for Biological Diversity Louisa has advocated for preservation of wilderness and wild animals of the Northern Rockies for over 40 years. Louisa specializes in developing comprehensive strategies that succeed because they work on multiple scales using various approaches, including grassroots organizing and outreach, education, media and communication, policy analysis, lobbying, coalition development, and public protest. She is especially passionate about grizzlies, wolves and other large carnivores. In 2015, Louisa and her husband Dr. David Mattson started Grizzly Times, www.grizzlytimes.org, and a podcast, https://www.grizzlytimespodcast.org/, to provide a voice for grizzly bears and the wild. Louisa has a BA from Williams College and a Masters of Forest Policy from the Yale School of Forestry and Environmental Studies. In 2014, she received a lifetime achievement award from the Yale School of Forestry and Environmental Studies.
