Kevin Damstra, Supervising Naturalist

Kevin gained his love of the outdoors in the woods and coasts of New England while he was growing up in the greater Boston area. After graduating from the University of Maine with a  BS in Parks, Recreation, and Tourism; Kevin traveled the country working for local, state, and National Parks, from Boston to the Redwoods, and Yellowstone. In 2009 Kevin was hired as a Naturalist by the East Bay Regional Park District at Black Diamond Mines, transferring to the Big Break Visitor Center in 2012 to help design and lead the new programs and exhibits found there. Now Kevin can be found in the hills from Sunol Regional Wilderness to Del Valle Regional Park, as the Supervising Naturalist overseeing programs and operations at two Visitor Centers and multiple parks. When not exploring these parks at work, he is often found chasing his two young sons through the same areas. 

Ashley Grenier, Naturalist / Volunteer Docent Coordinator

Ashley Grenier grew up in Castro Valley, and when she wasn’t on the soccer field or at a dance competition, her family could be found at the beach in Half Moon Bay, Lake Tahoe, and Kauai. Those experiences plus one transformative week of being a cabin counselor at outdoor school inspired her to earn a Bachelor’s Degree in Environmental Studies from UC Santa Cruz (Go Slugs!). She then went on to get a Master of Education degree with a focus on Environmental Education from the University of Washington. At Island Wood, a school in the woods on Bainbridge Island, she realized her desire to continue working outdoors and teaching people about the beauty and importance of the environment. Her love of the ocean led her to jobs in the aquarium world but she eventually made her way back home to the Bay Area to become a Naturalist for East Bay Regional Park District.

After more than 10 years in the world of Summer Camp and Residential Environmental Education, Alex joined the Park District in 2019 and is excited to continue to share her love of the outdoors with others.

Erica Stephens, Naturalist

Ever since her first visit to Yosemite when she was 10 years old Erica knew she wanted to be a ranger and naturalist. Her passion for the environment continued as she earned a degree in Natural Resource Interpretation and Paleontology from Humboldt State University.

Her lifelong career in interpretation has come full circle as she has returned to her home state to become a Naturalist with the East Bay Regional Park District where she can continue to share her love of art and nature.
