Great Brook Farm

“Bringing awareness of dairy farming to the broader community is a big part of what we do.”

Great Brook Farm sits on a state park in the town of Carlisle, Massachusetts. It is the only state park that has an active dairy farm. With more than 100,000 visitors each year, the Duffys and their milking herd are used to having an audience. “Bringing awareness of dairy farming to the broader community is a big part of what we do,” Mark says. Today, Mark and Tamma Duffy, their daughter, Marlow, and sons, Christopher and Blake, run a state-of-the-art dairy with a “smart” barn housing the first robotic milking system installed in Massachusetts. The Duffys also operate a seasonal ice cream and farm stand, raise cranberries and sell composted cow manure. “The good thing is that many people want to buy local products, and they support our work as much as they can,” Mark says appreciatively.

Marlow and Christopher have also been actively involved in our leading in school physical activity and nutrition program – Fuel Up to Play 60. Each of them have participated as speakers at several school events in Massachusetts helping connect students to their local dairy farmers.
