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!

Andrea Simeone-Austin (Wholesale/Retail Business Manager)

I grew up on one of the older Massachusetts farms in the greater Boston area. While the surrounding towns experienced unprecedented modernization, I understood that as a child of a farm family, I was the lucky one. Freedom to roam over open fields and spend most of my time observing and interacting with nature was and is the greatest of educations. Going off to college and into the working world only served to reinforce my need to return to the farm. I have worked on our family farm for close to two decades and have seen the farm grow from a simple subsistence farm to a vibrant business in the community. I have seen farmers struggle and succeed under arduous conditions and I am greatly encouraged by this generation’s newfound respect for farming. In my personal life, I have my own small farm raising chickens, fruits, herbs, vegetables, and beautiful perennial and cut flowers. I am the mother of a homeschooled son, I am a believer in self and experiential education to develop a thinking mind, I am a foodie in that I am an ok cook, but I am a great eater of good food, I am an amateur musician working toward a Berklee College of Music Certificate in Theory and Harmony. As my family farm winds down, by coming to work at Warner Farm I am celebrating my new connection with the dedicated and hardworking farmers at this wonderfully productive farm.

Kristen Whitmore (CSA and Market Manager)

I come from a family of farmers and agricultural workers. I grew up in Hadley where I started getting my hands dirty early on, gardening with my grandfather in our big vegetable garden, working at roadside stands, and helping run my family’s wholesale produce business. I studied at Mount Holyoke College, lived in Oaxaca, Mexico for a stint, and later in Caaguazu, Paraguay where I worked in Agriculture Extension with Peace Corps. After two years farming and community organizing in South America, I was drawn back to the Valley by the strong agricultural community and memories of lush green summers. I am passionate about local, sustainable agriculture, and love to compare notes with others about their latest projects in the garden and the kitchen, so feel free to share! I also speak Spanish and love to practice any chance I get. When you get in touch about our CSA or farmer’s markets, you will likely get me on the other end. I am happy to answer your questions, share information, and keep you in the loop!

Taylor Haas (Equipment Operator and Crew Manager)

Taylor Haas has been at Warner Farm since the age of 15. He is a Sunderland native, and recently graduated from the University of Rhode Island, where he studies Sociology and Philosophy. Taylor enjoys the wide range of job titles he can be held accountable for at the farm, and finds pleasure in spreading knowledge about the importance of eating fresh local food. On occasion you may see Taylor at the markets Warner Farm participates in, or at our CSA drop-off, but you're more likely to find him out in the fields on a tractor, or wholesaling our fresh picked veggies in the yard.
