Staff

Working to save the places you love.

We are a private, non-profit organization comprised of a small staff and many volunteers. As your regional land trust, we work in collaboration with communities, partners, and landowners, to protect forever the natural habitats, rural landscapes, and open spaces of west Puget Sound.

Nathan Daniel
Executive Director

Nathan has dedicated himself to conserving ecologically valuable lands on the Great Peninsula since he joined GPC as Executive Director in 2019. He has over a decade of experience in non-profit management with a focus on public lands and holds a master’s degree in Environmental Science. Nate knows that our region is an extraordinarily beautiful and special place and that as stewards it is our responsibility to protect the land and the native wildlife that call it home. He believes our children and all future generations should have opportunities to connect with the natural world. Nate knows the best way to get things done is through collaboration and is ready to work with community members who want to preserve habitat and protect biodiversity. When he’s not at his keyboard, you’ll find Nate and his partner Kim out sauntering through the forest, field guides and binoculars at the ready.

Ali Erskine
Conservation Associate

A born-and-raised Washingtonian, Ali studied Environmental Science at the University of Washington, and since then has been lucky enough to sample many of our local ecosystems: measuring trees from the Columbia Gorge to the Skykomish, quantifying ferns on the Olympic Peninsula, and pulling weeds and planting trees all around Puget Sound. Ali is incredibly excited to get to know the Great Peninsula and the dedicated stewardship volunteers who help protect it!

Janessa Hollmaier
Land Labs Site Coordinator AmeriCorps VISTA

Janessa will be serving her second AmeriCorps term as the Land Labs Site Coordinator VISTA and will be responsible for indexing GPC’s preserves for educational and outreach opportunities that will engage local students and community members. Janessa studied Environmental Science at Iowa State University and previously worked in higher education in student support roles. Since relocating to Washington in 2019, she served her first AmeriCorps term through the Washington Service Corps, performing environmental restoration and trail maintenance work. Janessa recently moved to Tacoma with her husband, two dogs, and cat and is excited to explore more of South Puget Sound as well as the Great Peninsula region. 

Sierra Kross

Most recently, Micaela completed her MS in Natural Resources and received a graduate certificate in Environmental Education and Science Communication from University of Idaho’s McCall Outdoor Science School Graduate Program. Whether it’s living with wolves in Colorado, building trails in Idaho, eating bananas in Peru, or managing research in the Frank Church Wilderness, she values finding work that mirrors her enthusiasm for life, and is overjoyed to find ways to play in the deep reaches of the Pacific Northwest.

Erik Steffens
Conservation Director

Erik is the Conservation Director for Great Peninsula Conservancy, overseeing land transactions to protect wildlife habitat, forest, farmlands, and the rural character of the peninsula. He has spent two decades working on conservation, restoration, and wildlife biology projects in the Pacific Northwest, mostly in Western Washington, but with formative stints in Oregon and British Columbia.

Katherine Tacke
Development & Communications Manager

Katherine was excited to join Great Peninsula Conservancy in the summer of 2018 and pair her interest in writing with her love for the outdoors. She grew up across the water next to an undeveloped greenbelt and spent her childhood exploring, counting birds, searching for frogs, and watching the rain against a backdrop of evergreens. After graduating from the University of Washington, she worked in books and publishing for several years, most recently at the UW Press in the marketing department. Katherine lives in East Bremerton with her partner, three cats, and dog. In her free time she’s usually gardening, hiking, or reading.

Dylan Tenney
Finance & Operations Manager

Dylan was thrilled to join Great Peninsula Conservancy as the new Finance and Operations Manager in November 2019. At GPC Dylan utilizes his experience as an accountant to help preserve and protect our beautiful little corner of the Pacific Northwest. Not your average “number-cruncher”, Dylan possesses a love of the outdoors that he has carried with him to all corners of the country, from climbing mountains in Hawai’i and Idaho to biking and kayaking all through Florida and Georgia. Now he is excited to give back to the Great Peninsula, a place he considers to be among the most beautiful and diverse. Dylan lives in Silverdale with his wife and two small children, and he enjoys going on walks or hikes, coaching youth soccer, and generally playing as much as possible. When he has a moment to himself, you’ll most likely find him playing or watching one sport or another or studying up on a topic of interest. Conservation is a recent favorite!

Claire Voris
Events and Outreach Associate

Claire is responsible for coordinating events, maintaining GPC’s social media, and designing education programs that will engage the next generation of conservationists. Claire recently moved to Bremerton from Missoula, Montana, where she completed her MFA in nonfiction writing, cleared trail as a Wilderness Ranger Intern for the Selway Bitterroot Frank Church Foundation, and spent two seasons packing mules for an outfitter in the Bob Marshall Wilderness Complex. Prior to her graduate studies, Claire worked in her home state of Illinois as a writer and editor designing e-learning and marketing materials for agricultural companies. When she isn’t working Claire loves exploring and photographing wild landscapes either on her own two feet or horseback. She is excited to work with GPC’s dynamic team of staff and volunteers and to continue learning about the peninsula’s unique ecosystems.

Adrian Wolf
Stewardship Manager

Adrian joined GPC as the stewardship manager in March 2021 and is committed to maintaining and improving the ecological integrity of natural ecosystems. The seeds of his connection to the land and land ethic were sowed in South Africa (where he was born and raised) through his family’s month-long summer adventures to wild natural places. He has over 25 years of professional experience working with threatened and endangered habitats, and the species that depend on them. Adrian has lived in the Pacific Northwest since 2003 and obtained his Master’s Degree from The Evergreen State College where his research work focused on bird use of epiphytes in an old-growth coniferous forest. He has extensive experience with handling birds through ecological research studies. His pastimes include birding, kayaking, and backpacking.
