Rachel is a veggie lover who firmly believes that healthy eating is the foundation for healthy communities, and it is this belief that initially drew her to Collective Roots. Through Collective Roots, her cooking blog Veggies At The Table, and work at Google, where she manages internal programs, comms, and marketing focused on food and wellness services, she aspire to get many more people enthusiastic about vegetables (and other plants too)!

Tammy has fond memories of growing up in Maine picking wild blueberries and working the family garden to meet the family’s nutritional needs and looks forward to working in an area tied to her environmental science education.

Lisa Young

Lisa Young ‘accidentally’ grew her first corn stalks after playing farmer with her sister when she was a child. Watching the corn grow and then harvesting the cobs started a life long obsession with growing food. She loves sharing this passion with others, and encourages her clients to grow herbs and vegetables in their gardens. With her background in non-profit fundraising campaign management and donor development, she is looking forward to helping Collective Roots grow, as well.
