Peggy Courtney
Peggy Kirk Courtney, a native of Mount Pleasant, South Carolina, graduated from Ashley High School. She then received a bachelor’s degree in psychology from Rhodes College in Memphis, Tennessee, and a registered nurse degree from Methodist Hospital University in Fayetteville, North Carolina. Peggy worked at Le Bonheur’s Children’s Hospital and The Med Neonatal ICU and Pediatric ICU in Memphis until her first child was born, after which she returned to Mount Pleasant. Desiring a more flexible work schedule as a new parent, she worked as a legal nurse consultant and medical case manager.
Peggy and her husband, Lawrence Courtney, an architect for the City of Charleston, have raised five sons in Mount Pleasant. When their youngest son joined the third grade class at USL, Peggy absolutely fell in love with the school. And so did Will, who graduated from USL in 2021. His only complaints were that the school days were too short and the summers too long. To say that USL gave him a true love of learning is an understatement.
USL not only meets each child’s academic needs, but also provides them with a high degree of emotional intelligence and an innate understanding of how to navigate the world as an adult. Peggy sees serving on USL Board as a great opportunity and honor to give back to a school that consistently gives so much to the students and community at large.

Along with his wife, he now calls Charleston, South Carolina home. He continues to travel, be intellectually curious and asks lots of questions. He has two sons who both attended USL and are now in University in Dublin and London. He would love to still be playing lacrosse and spends his leisure time kayaking, cycling, wood working, taking photos and trying to keep up with his two boys as they have their own international adventures.
