Working for Natural Resources Defense Council, Sierra Club, Center for Biological Diversity and Greater Yellowstone Coalition, Louisa has advocated for grizzly bear preservation for over 30 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 and a handful of others have prevented Yellowstone grizzly bear delisting for over two decades. Louisa has a BA from Williams College and a Masters of Forest Policy from the Yale School of Forestry and Environmental Studies. In 2014, Louisa was given a lifetime achievement award from Yale.
