Sara Fetterly, Supervising Naturalist

Sara began working for the Park District in the spring of 2001 at Ardenwood Historic Farm. After 10 years of potato planting and tomato tasting, she traded in her pitchfork for binoculars and moved to Crab Cove where she spent 5 beautiful years at the edge of the bay. But once a farm girl, always a farm girl, and in 2015 she happily accepted a position as Supervising Naturalist of the Tilden Nature Area and Little Farm. Prior to EBRPD, she held a variety of job titles including wildlife biologist, environmental consultant, and Peace Corps volunteer. Sara holds a B.A. degree in Environmental Geography from San Diego State University and a Masters of Education from University of San Francisco. In her spare time she loves traveling, hiking, camping, snowboarding, and spending time with her family.

Anthony Fisher, Naturalist

Hi. Anthony here. My naturalist training began when I was a small child playing in the open spaces and parklands of the Oakland hills. My older brothers and I explored every canyon and creeklet and nursed endless cases of poison oak. We found owl roosts, bluebird nests and sleeping foxes. Many years later, when I found out that there was a career to be had sharing these experiences with others, I procured a B.S. in Biology from San Francisco State. Now, I am fortunate to be able to share my love of birds, animal tracks, indigenous survival skills, camera trapping and all things nature-y with our park visitors. Hope to see you on the trail!

Trent Pearce, Naturalist

Trent joined the Park District in 2010, working at Ardenwood Historic Farm before coming to the Tilden Nature Area. Natural history has long been his passion; for the preceding six years he served as an interpreter for California State Parks and an environmental educator in the Santa Cruz Mountains. He came to California in 2006 after completing a degree in Foresty and Recreation from the University of Tennessee, where he also led guided backpacking and rock-climbing trips for students.  Trent is an autodidactic mycologist, photographer, and an avid birder.  When not sharing the joys of the natural world with the public, he enjoys long bike rides through the East Bay hills and paddling his kayak down Sierra Nevada whitewater rivers.

Jenna S. Collins, Naturalist

Jenna joined the Park District in 2011 at Ardenwood Historic Farm before joining the team at Tilden Nature Area. She has a degree in History with a minor in Latin from CSU Sacramento, and began working for California State Parks while attending college. For many years Jenna has worked for parks in California’s Sierra Foothills, Central Valley, Central Coast and the Bay Area. Her experience has given her a wide perspective of California’s natural and cultural history, from the North Coast and the Sierra Nevada, to the Mojave Desert. When not delving into California’s gold rush history, she enjoys hiking, keeping bees and generally anything involving being outdoors with family and friends.
