Registered Nurse and Clinical Nutritionist Betsy grew up in Raleigh the youngest of 4 girls and attended Leesville High School. She went on to attend Appalachian State University and earned a BS in Exercise Science with the goal of becoming a Physical Therapist. In preparation for PT school, Betsy spent time in the hospital as a nursing assistant to develop her patient contact skills and learn more about the medical field. It was this experience that opened her eyes to the field of nursing and the huge impact it can have on the lives of people in the community. She loved the hands on, physical, compassionate care that nurses provided to the sick and injured.
Betsy went back to school and earned a BS in Nursing from UNC Chapel Hill. After graduation she worked many years at Rex hospital in the Neuroscience unit as an RN before joining EHW in 2015. The past several years Betsy began to see the strong relationship between the food that people eat and the state of their mental, emotional, and physical health. She noticed that changing her own diet and the diet of her family really effected their energy, moods, focus and body composition. She decided to pursue a post-graduate certification in Clinical Nutrition so that she could further understand the biology and chemistry of nutrition and help teach it to others.
Betsy is thrilled to be returning to EHW in the role of Clinical Nutritionist. She will be using her knowledge gained in her functional nutrition courses to can help patients prevent the diseases that arise from poor nutrition and help treat and heal their current heath issues through diet and lifestyle changes. Random fact… Betsy once spent an entire month in the wilderness with no shelter. Eating, sleeping, cooking and bathing outside. Three weeks of this venture were in snow! The experience opened her eyes to the power of nature and how spending time outside can both ground and enlighten the spirit. Betsy currently lives in Raleigh with her husband, two children, and a crazy dog. She loves to hike, read, cook and hang out with her family.
