About Tuleyome

Tuleyome was founded in 2002 as a volunteer advocacy-oriented nonprofit conservation organization. Our mission is: "Tuleyome engages in advocacy and active stewardship with diverse communities to conserve, enhance, restore, and enjoy the lands in the region."

At Tuleyome we “live” our mission every day: we preserve and restore wild habitat, we build and repair trails, we educate the public about local conservation and environmental issues, we engage young people through our youth program, we demonstrate a good “land stewardship” ethic by maintaining the easements and properties we own under the scope of our land trust component, and we run campaigns that have a long lasting positive effect on the region.

It is our hope that our work will inspire members of the public to protect, restore, and enjoy the natural landscape in the Northern Inner Coast Range.

our board members

Stephen McCord, President

Stephen grew up running around forests and soccer fields in South Carolina’s foothills to the Appalachian Mountains. After receiving his BS in Civil Engineering from Clemson University he served as a Peace Corps volunteer in Mali (West Africa). Stephen received his MS and PhD in Civil & Environmental Engineering from UC Davis in the 1990s, and has worked as a water quality consultant based in Davis since 2000. He is a licensed Professional Engineer in California and a Certified Lake Manager. Because of his extensive involvement with UC Davis, he received a 2021 Distinguished Engineering Alumni award. Although he has visited over 50 countries, he loves to explore Northern California on his four bicycles (and a motorcycle), four boats, and in his many pairs of hiking shoes. He recently stepped down after over a decade of service on the board of directors for another local nonprofit, Putah Creek Council. His involvement with Tuleyome over the past two decades has been as a donor, volunteer, California Naturalist guest speaker, tour guide and contracted project manager. He has gained expertise dealing with mercury as an environmental pollutant through various projects assessing and remediating mercury mine sites.

Bill Grabert, Treasurer

Bill became a Tuleyome staff member in 2016, retired in 2021, and has continued his involvement with the organization as a volunteer. His staff roles included activities/education coordinator, lecture series host and California Certified Naturalist instructor. Bill fell in love with the natural beauty of the Berryessa-Snow Mountain area while working as a geologist in the geothermal fields of Lake County in the late 1970’s. He earned a double major BA in Environmental Biology and Geology from UC Santa Barbara. After a decade or so exploring for geothermal energy, Bill earned an MBA from San Francisco State University and started a second career in Information Technology designing and managing Health Care and Financial Information systems. Bill’s next, roughly decade-long, career was as a stay-home dad, scout leader, parent volunteer and home manager. In 2016, finding and joining Tuleyome was the perfect place to consolidate such a wide range of life experience into a final career. Bill is honored to continue his contribution to Tuleyome and the people of Tuleyome’s focus area as a board member.

Glen Holstein, Board Member

Dr. Holstein received his PhD in Botany from U.C. Davis and is retired from his position as Senior Scientist with Zentner and Zentner, a local biological consulting company. He has published peer reviewed research on California Prairie in Madroño, the journal of the California Botanical Society. Glen is Chapter Botanist for the Sacramento Valley Chapter of the California Native Plant Society , represents that Chapter at Habitat 2020 and was the California Prairie spokesman at its Wildflower Weekend in April , 2005 . He is also on the Board of Tuleyome, a non-profit organization working to protect the Cache Creek watershed and other areas in Yolo County, and on the steering committee of Yolo County’s Natural Communities Conservation Plan (NCCP). The NCCP program is an unprecedented effort by the State of California, and numerous private and public partners, that takes a broad-based ecosystem approach to planning for the protection and perpetuation of biological diversity. An NCCP identifies and provides for the regional or areawide protection of plants, animals, and their habitats, while allowing compatible and appropriate economic activity.

Lyndsay Dawkins, Board Member

Lyndsay is one of the founders of Nature’s Theater, a program which provides nature-based programming and opportunities for school-aged children. Lyndsay’s passion for the outdoors developed from a childhood of camping trips and world travel. She earned a BFA from U.C. Santa Barbara in Theater Arts with an acting emphasis. Lyndsay spends most of her time writing, expanding the scope of Nature’s Theater, playing with kids and enacting characters like Mother Nature, Star Walker or the Jester. Nature’s Theater will help shape the junior guide program for the new Woodland Regional Park with walking stories featuring teens as costumed characters guiding young kids through nature themes with story driven adventures that teach appreciation of nature.

Steve Drown, Board Member

Steve has been involved with environmental issues since his youth in Boy Scouts.  He pursued his interest in college (degree in Environmental Geography), law school (environmental law at University of Oregon), and professionally, when he served as an environmental attorney for 13 years.  Although his professional focus broadened in the past 20 years, when he served as UC Davis Chief Campus Counsel and Senior Counsel for the University of California, his service to Tuleyome has offered him the opportunity to return to his initial interest in youth engagement in the natural environment.  Steve, on behalf of Tuleyome, has developed the “Boot Bank,” which offers free high quality hiking boots to area youth throughout their growing years (up to 18) to encourage them to engage in, and value, their surrounding natural environment.  Hopefully, these youth will become the next generation of conservationists.

Jake Glassman, Board Member

Jake is an environmental professional with experience in both the clean energy and conservation fields. He currently works on the state policy team of the US Program at RMI (formerly Rocky Mountain Institute), engaging with leading states to increase the speed and scale of their climate policy.

Chelsea Ferguson, Administrative Assistant

Chelsea's love for the great outdoors was instilled in her from an early age, growing up in the stunning mountains of Northern California near Yosemite. She spent much of her childhood exploring the surrounding forest, hiking and climbing among the trees, and marveling at the natural beauty around her.
As she grew older, Chelsea continued to find ways to immerse herself in nature, taking advantage of the area's plentiful natural resources. In the summer, she could be found wakeboarding and skating on the nearby lakes, while winter brought the opportunity for snowboarding and other winter sports.
Despite her connection to the outdoors, Chelsea initially pursued a career in hospitality, which brought her to Sacramento in 2018. Over time, however, she began to feel a strong pull back to her roots and her love for nature. Determined to find a way to merge her passion for the environment with her professional life, Chelsea began exploring opportunities to work in the environmental sector.
She is now proud to be a part of the team at Tuleyome, where she can combine her passion for the environment with her professional skills. Whether she's in the office or out in the field, Chelsea brings a tireless work ethic and a deep sense of purpose to everything she does. She is dedicated to making a positive impact on the planet and helping to preserve the natural beauty that has always been so close to her heart.
In her free time, she can still be found exploring the great outdoors, hiking and camping with her partner in the mountains she has always called home.
