Originally from Tennessee, Debra attended school in Sacramento, then traveled extensively throughout the Pacific Northwest before finally settling on a small farm in Northern California with her husband Dave. Debra became an ardent volunteer in the 1970s and 80s and has over twenty-five years of experience in the non-profit industry. Honored in 2009 by the California Legislature and the Yolo County Women's History Committee as a "Woman Taking the Lead to Save the Planet," she has held senior positions with organizations that focus on building environmental literacy, conservation ethics, conserving wildlife habitat, land preservation as well as advocating for science, health and social justice. Her strengths lie in fostering change and meeting environmental, social and community needs through strategic planning, community education, fundraising and organizational development - assisting nonprofit organizations in realizing their full potential by connecting their vision to community impacts. She and her husband Dave consider their ongoing passion for environmental activism as part of their responsibility to make sure that future generations will enjoy the wildlife of today, especially the majesty of the mountain lion.

Debra was appointed to serve as CEO in November 2019.
