Carmen Snyder

Executive Director

When living in an intentional farming community in North Carolina, Carmen fell in love with farm life and food production, especially enjoying bee-keeping, food preservation & fermentation, hand-milking goats & cows, and making dairy products. Over the course of her career, she has worked as a middle school English teacher, yoga instructor, head of the kitchen for various events, and principal organizer for the Southeastern Permaculture Gathering.

Inspired by Sonoma County’s thriving, diverse agricultural community, Carmen is passionate about supporting local farmers and working to preserve farms forever. She oversees Farm Trails operations and events, from budgets to band selection, and is most interested in cultivating community, bridging gaps, building resilience, and fulfilling Farm Trails' mission to instill an appreciation of ag as a vital part of our lifestyle.

Carmen serves as Treasurer of the School Garden Network of Sonoma County and sits on the advisory board of Colorado State University’s Western US Agritourism Project. She is also the Producer of the Gravenstein Apple Fair.

Sophie Haag

Gravenstein Apple Fair Event Coordinator

Sophie was born and raised in Humboldt County. The value of local food systems and small businesses has been an important part of her life since childhood. She moved to Sonoma County in 2022 to work for the Occidental Arts and Ecology Center as a Programs Administration intern where she found strength and connection in West County's deeply intertwined community. In early 2023, she joined the Farm Trails team as the Gravenstein Apple Fair Event Coordinator. She lives in Sebastopol with two of her closest friends and dreams of one day adopting a dog. In her free time, you can find her struggling to finish a sewing project, trail running, or searching for treasures at her favorite thrift store.

Lisa Rose


A Northern California native moved from Marin to Sonoma in 2018 where the rolling hills and seasonal beauty of Sonoma County have always been her favorite visual treasure. Lisa has been photographing people places and things professionally for over 32 years. Her life behind the camera is a vibrant world where imagination and real life combine moment to moment.

Since moving to Sonoma, Lisa has realized a beautiful dream. In 2020 she formally started Revival Groove Urban Microfarm, a half-acre farm focused on growing fruit and vegetables year-round, building community around healthy locally grown food through her mini CSA. Lisa enjoys working with people in their own gardens so they too can grow food too.

In 2022 Revival Groove became a member of Farm Trails and had her first booth in Life on the Farm at the Gravenstein Apple Fair. In fall of 2022 Lisa joined Farm Trails team as staff photographer and couldn’t be happier being connected to such a dynamic agricultural community. Lisa teaches hands-on photography workshops to members, hits the Farm Trails for Spring and Fall tours to capture the members and the public as well as cruising the county as the seasons change to collect images for the annual Map and Guide.

Lisa lives in Santa Rosa with her 2 daughters and their 2 dozen hens, 3 ducks, 1 rabbit, 4 cats, and 1 dog. On any given day you will find her with hands in the soil and watching her hens cluck around at sunset.
