Farm Team

Mike Wissemann

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!

Lacey Arnold

Wholesale Manager


Lacey is a transplant to both the Pioneer Valley and to the world of farming. After growing up in New Jersey and graduating with a degree in Broadcasting, she spent three years working in public access TV before embarking on a year-long road trip to travel the country and hike our National Parks. Along the way she found her passion for living, growing things. Upon return from her travels she joined the Warner Farm team, starting out as a Mike’s Maze employee and rising to her position today. Lacey is thrilled to share her love of plants, food, and life itself with her community and to connect folks with fresh, local produce grown with lots of love!

Phoebe Gelbard

Direct Market Manager


With her roots in Western MA, Phoebe grew up surrounded by the incredible farmland that the Valley is known for. Prior to shifting her focus to the local food realm, Phoebe taught at an outdoor environmental education school for five summers where she gained a deeper understanding of the geology, ecology, and indigenous history of the area. After graduating with a degree in Sustainable Systems from UMass Amherst, Phoebe served on the Warner Farm CSA crew for the 2020 season. She is beyond excited to continue working with the team and is eager to learn more about how farms can play an increasingly integral role in ensuring equitable access to food for all – both within and beyond our community.
