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 nicest produce that you’ve ever seen or tasted; to be active participants in a vibrant local food economy; and to take care of our farmland to the best of our ability.


We’re a family-farm, in our 15th 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 enhance our fields’ soil fertility by using natural composts, cover crops, and mineral amendments. We have chosen to forgo the USDA’s organic certification process but invite you to trust us, your farmers, that we grow our produce using ecologically and socially responsible methods, on par with current organic standards.

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 helping tend gardens, fruit trees, and a collage of farm animals his family raised for home consumption. 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, named Siena, in 2005, spawned a new incarnation of the farm — Siena Farms.

Growth: Over the last fifteen years we’ve grown to our current scale of 50 acres, and now serve our CSA members, restaurant clients, and retail customers — year-round in Boston’s South End and at the Boston Public Market, and seasonally at the Copley Square 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 an opportunity for our retail customers to engage further with the farm and our produce.

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