The farm was first established in 1719, by Solomon Holman and in time was passed down to his son Col. Jonathan Holman after the Revolutionary War; the original farm of 3,000 acres was a land grant from the King of England.

In 1934, Oscar and Ester Pearson opened the current retail store and processing plant, using milk from the neighboring farm.  The Pearson’s delivered milk to nearby communities through several routes. Later joined by their son Robert and his wife Barbara they continued the business.  Today with the help of their children Bob, Cindy, John and his wife Fran and their son Cody, daughter Brittany and son in law Rob and grandson Gabriel, they have expanded the business to include making 26 flavors of delectable ice cream, processing maple syrup, a cut your own Christmas Tree Farm and harvesting cord wood for sale in addition to the milking and processing plants.

In 1987, the Pearson’s purchased the current milking facility located ¼ mile from the processing plant. The facility built in 1930 is a traditional tie stall barn that houses 60 milking cows with a pipeline system and rotational grazing. The Pearson’s raise all of their own replacement heifers for a herd made of equal parts Holstein and Milking Shorthorn with an average of 3.8% butterfat. Currently the farm consists of 300 acres, of which 70 acres are hay fields and 35 acres are cornfields, which in the winter are converted to a cover crop of winter rye. In 1990, the Pearson's placed 263 acres of the land into the Agriculture Preservation Restriction Program (APR). For the last 15 years the Pearson's have participated in a program with the local elementary school system in which the school adopts a baby calf for the school year. The children visit the farm monthly to view the growth and development of the baby, and to learn more about farm life and agriculture. Additionally, the Pearson family is very involved with the county and state 4-H programs. They have been leasing high quality show heifers to 4-H youth as well as supporting the state calf sale by consigning animals yearly. Additionally, they continue to show on a state and national level.

 
In 2008, the Pearson family was chosen to receive a grant from the Massachusetts Technological Corporation to build solar panels on the roof of the barn to generate electricity for the farm. Currently the photovoltaic cells produce 7,000 kilowatt hours per year which is 1/5 of the farm's annual energy use. The Dairy Farm has been consistently recognized for its high quality milk and dairy products and low somatic cell counts (low bacteria counts). In 2010, Elmhurst Farm was recognized by the State of Massachusetts as one of the top 1,000 places to visit in Massachusetts, or 1 of 136 in Central Massachusetts and awarded the Greener Pasture Award by Eastern State Exposition as Massachusetts Outstanding Dairy Farm. In 2013, DairyLea awarded the farm for 12 conservative months of low somatic cell while maintaining a high butterfat ratio.
