Asa / “Chert”

staff-sempervirens-asaChert grew up in the Sierra Nevada Mountains and spent his childhood hiking, backpacking, skiing, climbing trees, and jumping off of rocks into the Stanislaus River. He picked up the guitar in middle school, and has since put it down only a handful of times. He had one of those ‘life changing events’ when he traveled to Exploring New Horizons at Sempervirens to be a cabin counselor. This would alter his path towards the world of outdoor education and ultimately lead him to his current position as Program Director.

After graduating high school, Chert lived, played, and went to school at UC Santa Cruz. There he not only continued his outdoor adventuring and guitar playing, but picked up the mandolin and juggling as well. Later in his college career, he fell in love with rock climbing and has based many of his California travels around the best areas to climb. Following his love of rocks and all things outdoors he graduated with a Bachelor of Sciences degree in Geology. After spending a year working at San Mateo Outdoor Education, he made his way back to Exploring New Horizons at Sempervirens to work as a naturalist for three years before bringing his path full circle and becoming Program Director.

Deanna / “Decay”

staff-sempervirens-deannaDeanna grew up playing in the dirt and water of Wisconsin in search of cool bugs, plants and animals. She later received her environmental geography degree which involved research projects in Yosemite, western Wisconsin, and the hill country of Texas studying the effects that humans have on land, water, and wildlife. Now she’s back to playing in the dirt in search of cool creatures, now with added elements of collecting data to play around with for graphs, mapping and analysis! All way more fun than it sounds. When she’s not nerding out over nature with kids, she’s likely swimming, canoeing, painting, playing around on a drum or ukulele, cooking, and in the right climate, building snow sculptures!

Samantha / “Clover”

Lauren/ “Sage”

Sage grew up in the Bay Area and is beyond happy to be back after spending the past several years in Southern California. She spent her early years riding horses, doing ranch work, and volunteering as a junior docent at Ardenwood historic farm. She went to college at UCSB and majored in psychology, and during that time she worked at a local food co-op where she developed her love for cultivating and preparing food. She taught cooking classes at an after school program before heading to sunny San Diego for grad school, where she got her teaching credential and M.Ed. But instead of wanting her own classroom, Sage answered the call of the wild and fell in love with outdoor education. When she’s not in the office or out visiting schools Sage likes to play guitar, stargaze, bake, snowboard, practice yoga, daydream about homesteading, swim, plan road trips, hike with her dog, and take naps with her cat.

Rebecca/ “Heron”

Growing up in Los Angeles, Heron got the opportunity to explore natural spaces at a variety of camps that she attended throughout her childhood. Camp fostered her love of forest and sea, which she followed to the University of California Santa Cruz. During her sophomore year, Heron took her first step on the path to becoming a Naturalist when she decided to enroll for fun in a Natural History class. Excited by experiential learning, she continued to pursue outdoor education with a field study course her junior year. Natural History Field Quarter taught Heron the fundamentals of field journaling as she followed the spring in California from the Mojave to Mono Lake. During that quarter, her idea of education revolutionized and she realized she wanted to spend her life connecting people to nature through outdoor education. Heron has since taught in the Sierra Nevada Foothills and in Washington State. Heron is grateful to be back in the Santa Cruz Mountains to share the wonder of the redwoods with students at Sempervirens.
