Stonyfield Organic

Stonyfield Organic is one of the United States’ pioneering organic dairy companies, founded in 1983 in Londonderry, New Hampshire. Co-founded by Gary Hirshberg and Samuel Kaymen, the company began as a small organic farming school and grew into a nationally distributed brand of certified organic yogurt, milk, and other dairy products. Stonyfield is committed to supporting organic family farms and ensuring that its dairy supply chain meets rigorous animal welfare and ecological standards. The company works with a network of independent organic dairy farmers, helping them navigate the economics of organic certification and access premium market channels. Stonyfield has made significant investments in reducing its environmental footprint, including measuring and offsetting the greenhouse gas emissions of its entire product life cycle. It was an early corporate advocate for eliminating bovine growth hormones from dairy production and for stronger organic labeling standards. Since becoming part of the Lactalis Group, Stonyfield continues to operate with a focus on its founding mission of organic and environmental stewardship. The company engages in climate advocacy, supporting policy changes that promote soil health, carbon sequestration in dairy farming, and biodiversity. Its history as a mission-driven organic business makes Stonyfield an important part of the story of how organic food moved from niche health stores to mainstream American supermarkets.
