Bridget Fithian, Executive Director

s_bfithianSierra Foothill Conservancy is pleased to announce the selection of Bridget Fithian as Executive Director. Bridget will now oversee the entire organization, reporting directly to the Board of Directors.

Bridget grew up in Mariposa. She attended University of California at Santa Cruz, earning a B.A. in Literature. After graduating from college, Bridget returned to her hometown, and begin working seasonally in Yosemite National Park. In 2008, she started at Sierra Foothill Conservancy as a volunteer and member. Impressed with her work, the conservancy quickly hired Bridget into a staff position, putting her in charge of community outreach. In 2011 Bridget was promoted to Conservation Director.

When asked about her time as Conservation Director, and what she was most proud of, Bridget quickly offered The Stockton Creek Preserve.

Through partnership with the Mariposa Public Utility District (MPUD) and Sierra Nevada Conservancy, Bridget established Mariposa’s first publicly accessible preserve. The Stockton Creek Preserve provides hiking and walking trails for locals and visitors, training grounds for the high school track team, and protects the town’s primary water source. Sierra Foothill Conservancy & MPUD are currently working to expand the trail system and manage overgrown vegetation, making the preserve more accessible and fire safe. Stockton Creek highlights one of Bridget’s greatest strengths, and one that she brings to her new role as Executive Director: that of a bridge builder.

Gardening, photography, and hiking with her husband Ben and red heeler, Dusty, are Bridget’s favorite pastimes.

Sustainability across every level of the Organization is a trademark, and her role as Operations Director is the perfect platform.

Chris Velez, Land Steward

Chris Velez moved to the Prather foothills with his wife Jamie Carr in 2000. They were working at a small Sonoma County specialty nursery and were introduced to organic farming at Santa Rosa Jr. College.  Chris put his goal of farming on hold while working at Intermountain Nursery and discovered his love for the foothills and native plants.

In 2003, Chris started Stella Luna Farm, where he provided the foothill community with mixed vegetables through a CSA. After 13 years of growing in the hills, he left the farm with the goal of working on a much larger scale and found that opportunity with the Sierra Foothill Conservancy as a Land Steward.
