Farm Team

Mike Wissemann
Owner

MikeWissemannMike 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. Encouraged by the increasing youthful interest in agriculture as a way of life, he is excited by new opportunities at the farm.

David Wissemann
General 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!

Jess Marsh Wissemann
“Farm Wife” and Co-Creator of Mike’s Maze

Jess married into the Warner Farm family in 2014, but her love of farming started at a very young age picking peas and strawberries in her grandfather’s garden. She managed the Warner Farm CSA for 4 seasons from 2010-2013 before starting her “day job” as the Food, Farm, and Sustainability Coordinator at Hampshire College. Also the creative force behind Warner Farm and Mike’s Maze, Jess spends all of her spare time helping to beautify and promote the farm. Jess can often be found greeting customers at the farmer’s market and in the U-Pick strawberry fields, taking photographs for our website and facebook page, and scheming up next year’s maze design!

She spent time tending to her grandfather’s vegetable garden, working at the family roadside stand, and delivering fresh local vegetables throughout the region. After attending Mount Holyoke College, Kristen spent two years in rural Paraguay where she worked with local subsistence farmers to increase the productivity and diversity of their family farms.

Virginia SchwarzenbachVirginia grew up on a poultry farm in Hampshire County. She left farm life, but is still drawn to the sights, sounds and feelings of connecting with the land. As they say, “you can take the girl off the farm, but you can’t take the farm out of the girl.” With a degree in communications, years of experience in customer service in the corporate environment and most recently event planning for a non-profit trade association, Virginia is happy to be back to her roots.  Her position at Mike’s Maze at Warner Farms is ideal fit for her passion for helping the family farm stay viable by giving the public a place to connect with a local farm and have fun while doing so!
