Dr. Langdon, a Harnett County native, graduated from the North Carolina School of Science and Math way back when it was a new idea. She went on to receive her Bachelor of Science, summa cum laude, from NC State University, where she was a Caldwell scholar. She graduated with her M.D. from Duke University School of Medicine and completed her pediatrics residency training at the University of Virginia. She then returned to rural NC to practice. She has served as the Chapter Breastfeeding Coordinator for the NC Pediatric Society, served on the Policy Committee, and is now on the Leadership Team and the Workforce Issues committee. She has been actively involved in advocacy for child health for many years. In August of 2022, she became the Clinical Chair of Pediatrics at the Campbell University School of Osteopathic Medicine and in March 2025 she was named the Director of the CU Health Center. She also currently serves as the vice-chair of the Harnett County Board of Health and serves on the Harnett Health Foundation. Dr. Langdon is a medical liaison with the NC DHHS on a Human Donor Milk Program Initiative and serves on the Opioid Task Force. Two of her six adult children were adopted from foster care, and she has a heart for the children in the foster care system. She has many passions including mental health and medication management for ADHD, anxiety, and depression in children and adolescents. She tries to be a loud voice to educate the public that vaccines are both extremely safe and extraordinarily effective. Concerned by the amount of misinformation on social media, she developed a YouTube channel and now is on multiple platforms. When the American Academy of Pediatrics told pediatricians to tell their stories, she did just that and wrote a book titled Doctors Work in Air Conditioning, an intimate look at Southern culture and the challenges of rural medicine. She married her high school sweetheart, Mark, when she was only 19 and they live happily on his family's farm with the cows, donkeys, horses, sheep, chickens, dogs and cats.
