Mike Wissemann (Owner)

Mike has been living and working at the farm since his high school days. He began working with Charles Warner while he was studying at Northfield Mount Hermon School. He graduated from UMass in with a degree in Plant and Soil Sciences. Mike quickly engaged his farming dreams, buying the farm and running the Millstone Farm Store across the street in his early twenties. In his lifetime, he has seen Warner Farm transition from production of primarily potatoes and onion plants to a diversified model of vegetable and fruit production, a transition he takes great pride in. Today, he is encouraged by the increasing youthful interest in agriculture as a way of life, and is excited by new opportunities at the farm.

David Wissemann (CSA and Organic Field Manager)

Other than Mike, no one knows Warner Farm better than Dave. He has spent most of his childhood playing in the dirt and running through corn fields here at the farm. He grew up watching his father and Grandpa Warner farm this land and is happy to be continuing the family business as the tenth Generation of Warners to farm in the Pioneer Valley! Dave attended The College of Wooster and majored in Wildlife Biology. While he loves farming, his other passion is observing and studying wildlife. This love of wildlife has brought him to all parts of the country including the Great Plains of South Dakota and the mountains of both Montana and California. He can often times be caught watching the various wildlife that lives around the farm and was excited to discover a pair of bald eagles that nest on the edge of our farm!

Kristen Whitmore (CSA and Market Manager)

Kristen comes from a family of farmers and cooks. She grew up in Hadley where she started getting her hands dirty early on, gardening with her grandfather in their big vegetable garden, working at roadside stands, and helping run her family’s wholesale produce business. She studied at Mount Holyoke College, lived in Oaxaca, Mexico, and later in Caaguazu, Paraguay where she worked in Agriculture Extension with Peace Corps. After a few years of farming and community organizing in South America, she was drawn back to the Valley by the strong agricultural community and memories of lush green summers. She is passionate about local agriculture and loves to compare notes with others about their latest projects in the garden and in the kitchen, so feel free to share! When you get in touch about our CSA or farmers markets, you will likely get her on the other end.
