Kelly Fritch, Gardening Teacher

Let's play in the dirt!

I am grateful for the opportunity to share my love of gardening with the upper grades. I came to UC Davis in 1993 to study Botany. I developed an interest in Sustainable Agriculture and decided to pursue a Masters degree. During graduate school I had the opportunity to do an internship with USDA in the south of France researching biological control of insects.. My teaching experience is through Davis Farms to School and Community Alliance with Family Farmers. As the farm to school coordinator I helped to procure healthier, local farm foods in the school cafeterias in both Esparto and Davis. I own a landscape design company and I am keenly interested in permaculture and the creation of food forests. I am also a functional medicine health coach helping clients feel better through goal setting around nutrition, sleep, exercise etc. In my free time I enjoy visiting beautiful natural places where I can jump in the water and mountain bike with my son Landon. 



Kelly Trunnelle, Handwork Teacher

I've always lived in California, and currently live in Woodland with my husband Jeff, our 10-year-old daughter Renee (a rising 5th grader here at DWS), 3 dogs, 1 cat, 1 bunny, 10 chickens and way too many plants to count!  I have a B.S. in Chemistry from SFSU and a Ph.D. in Agricultural and Environmental Chemistry from UCD and am currently an adjunct chemistry professor at Sacramento City College.  My free time is spent crafting, gardening, and baking.  I've been sewing since I was a little girl and knitting and crocheting since I was a teenager.  When Renee joined DWS in preschool my eyes were opened to a whole world of beautiful handmade objects and I have loved volunteering, and eventually substitute teaching for our wonderful handwork teacher Mrs. Haberman.  I am very excited to work with your children this year, we are going to have so much fun, and make so many beautiful things together!
