She hopes all campers leave Mercer Slough with a new appreciation for the natural world of the Puget Sound watershed.

Lisa Keith – Lead Educator
Lisa grew up near Olympia and spent her childhood playing in the woods, raising tadpoles and woolly bear caterpillars (separately, thank goodness) and exploring tide pools on Puget Sound. As a child, she wanted to be a ranger or a wildlife biologist, but got a little distracted. Years later, after an MA, work in hospice, a stint as a professional gardener, and a serious habit of science and naturalist volunteerism, it dawned on Lisa that becoming a science educator could allow her to pursue her childhood dream. These days, she’s exactly where she wants to be when she finally grows up: geeking out over macroinvertebrates and all things environmental science, and playing and learning in nature with kids of all ages.

Her studies as a field biologist have taken her all around the world to research sea turtles, frogs, lizards, spiders and bees. She’s spent time in Costa Rica, England, Indonesia and a bunch of other places. Dakota grew up in Connecticut and made the big move to Washington only a few months ago. She decided to move here after hiking the Pacific Crest Trail last year and falling in love with the Washington section. She is excited to learn and teach more about Washington natural history!
