The Farm

Committed to sustainable agriculture, fair accessibility to food and ecological land management.


Situated in the Tunitas Creek Valley of Half Moon Bay California, our 300 acre farm and wilderness property is one mile from the Pacific Coast.

Building healthy soil that will produce healthy plants is at the core of our farming practices. Crop rotation, cover cropping and organic compost are key tools in our operation. We never spray synthetic chemicals, placing the balance and vitality of the whole farm over any single pest or disease challenge.

Potrero Nuevo Farm provides charitable works in partnership with Abundant Grace Coastside Worker. The Farm donates use of its land, harvest support, seed, use of farm equipment and other materials to Abundant Grace Coastside Worker which feeds the low-income and homeless communities. We are pleased to help further the mission of Abundant Grace Coastside Worker, and also the Farm’s mission of providing healthy produce to charity.

We host a U-Pick Club for local families, an educational program for Pilarcitos High School’s “Coyote Farms Project” and farm tours for community groups.

Potrero Nuevo Farm stretches from rolling pasture to flat fields, with Tunitas Creek running the north border. We have a cool, foggy climate and produce an abundant variety of crops. We are eight miles south of Half Moon Bay and one mile from the Pacific Ocean.

Protected Forever

The productive soils, wildlife habitat, and scenic, rolling pastures of our 300-acre farm are now permanently protected by an affirmative agricultural conservation easement that we executed with Peninsula Open Space Trust (POST) on October 29, 2015.

The easement does two things: it protects the natural resources of our property and ensures that a portion of the land stays in working agricultural production, for both grazing and row crops. Our farm will always have at least two acres of row crops in production and 100 acres actively grazed. This innovative conservation solution ensures that our vision for Potrero Nuevo Farm is maintained for the local community’s enjoyment and benefit well into the future. Ours was one of the first such agreements created on the Coastside by POST's Farmland Futures Initiative and we are happy to be an early adopter of an easement that will guarantee agricultural land production in San Mateo County.

Additionally, we are happy to announce that Potrero Nuevo Farm will eventually pass to POST in our estate plans. POST and we share the same values and long term vision for land conservation and it is a delight to know that they will be there long after we are keeping this property protected and in agricultural production.

The Team

Christine Pielenz


Christine hails from Germany. After coming to San Francisco in 1995 she founded the family foundation Potrero Nuevo Fund with her husband, Bill, which supports after-school arts education, school garden programs and sustainable architecture for low-income communities. She always has enjoyed growing her own vegetables; in 2008 she decided she needed more space to grow things and bought Potrero Nuevo Farm.

Bill Laven

Bill taught literature at the secondary level for 8 years and photography from the secondary to post-graduate level for 20 years until he retired from teaching to found the Potrero Nuevo Fund with Christine. He now runs the farm with Christine.

Jay Trexler

Farm Manager

Jay came on board at PNF in 2011 to co-manage with his wife Suzie. The two first farmed together at the UCSC Farm & Garden apprenticeship, where they met in 2008. Since then he’s been farming on the Coastside and leading wilderness therapy trips in Oregon, but he is happy to be back in the soil and working together with his wife on the land where they married. When he’s not farming, Jay enjoys woodworking and picking out old time tunes on his claw hammer banjo.

Suzie Trexler

Farm Manager

Suzie found her way to farming as a Boston food critic. She quickly realized that she had no business writing about carrots and kale until she knew where it all came from. She volunteered at east coast farms like The Food Project and Siena Farms before landing an internship at Spannocchia in Tuscany, Italy, working with heritage breed farm animals. From there, she apprenticed at UCSC’s Farm & Garden and met Jay – her future husband and farming partner. The act of farming, for Suzie, is a grounding force that provides connection to everything that matters. Suzie is excited to be in her sixth season at Potrero Nuevo Farm.
