We believe that our emphasis on soil health as well as freshness makes a real difference in the flavor, nutrition, shine, and storage quality of our produce. We collaborate with some of the region’s top chefs to develop our crop varietal selections and harvest techniques. Our goals are to grow some of the best fresh produce that you’ve ever seen or tasted and to take care of our farmland to the best of our ability.


We’re a family-farm, in our 12th year of operation, cultivating 50 acres of protected farmland in Sudbury and Concord, MA — just 25 miles west of Boston. We grow over 100 varieties of vegetables for our 500-member CSA community, our farmstores in the Boston Public Market and Boston’s South End, our stall at the Copley Square Farmers’ Market, and select restaurants and chefs.

We use only sustainable agricultural practices; free of chemical herbicides, pesticides, and synthetic fertilizers. We increase our fields’ soil fertility by using natural composts, cover crops, and mineral amendments. We have chosen to forgo the USDA’s organic certification process and invite you to trust us, your farmers, that our produce is grown using ecologically and socially responsible methods.

Our Story

Germination: In 1975, when farm owner Chris Kurth was a mere babe, his family moved to a nineteenth-century Sudbury farmhouse and started settling in. Chris grew up tending home gardens, fruit trees, and even a goat that was his elementary school’s mascot. In 1998, after studying biology, philosophy, and environmental studies at Williams College, Farmer Chris started a ten-acre CSA farm on his parents’ fields and named it Meadow Brook Farm. After four years of developing Meadow Brook he accepted a farm instructor’s position at The Farm School in Athol, MA, during which time he met and married his wife Ana Sortun, chef/owner of Oleana restaurant and Sofra Bakery in Cambridge, MA, and Sarma mezze bar in Somerville, MA . The birth of Ana’s and Chris’ daughter Siena in 2005 spawned a new incarnation of the farm — Siena Farms.

Growth: Over the last decade we’ve grown to our current scale of 50 acres, and now serve our CSA members, restaurant clients, and retail locations (year-round in Boston’s South End and at the Boston Public Market, and seasonally at the Copley Farmers’ Market). In recent years, we launched our unique Kids’ Farm Share designed to get kids into the kitchen and connected to their food plus our Market Card program as a hybrid CSA option for our retail customers to build a relationship with the farm.

Harvest: Of course, we couldn’t have achieved any of this without our dedicated staff and farm crew, wonderful customers, and many friends — so, thank you, Cheers, and Happy Eating!
