Jessica received her Doctorate in Veterinary Medicine from Texas A&M University and practiced small animal veterinary medicine for 11 years in the Coastal Carolinas. When her daughters were 6 months and 3 years old she and her husband took the family on a European vacation and then moved to the mountains of Ecuador where they lived and traveled around the tiny, biodiverse country for 6 months before moving to Oregon. Her love of cooking and nutrition led her to volunteer in the school kitchen when her oldest joined the primary classroom in 2015 and she officially joined the kitchen staff in 2018. When not working in the kitchen you may find her leading her kindergartener scouts, giving breastfeeding support as a La Leche League leader, camping, cooking, or experimenting with different craft media.
