Devi Walters

MD, FAAP

Dr. Walters grew up in Augusta, Georgia, and then earned her undergraduate degree in Biochemistry from Georgia Tech before attending the Medical College of Georgia for medical school. She always had a heart for children, so pediatrics felt like the natural path when her love for medicine grew.

She completed her pediatric residency at Prisma Health, where she discovered a special passion for outpatient pediatrics. She values the opportunity to build long-term relationships with patients and their families and considers it a privilege to walk alongside them through every stage of childhood.

Dr. Walters met her husband, Ryan, during medical school. He is a family medicine physician, who enjoys running and makes amazing sourdough bread. Together, they have three fun and energetic children who keep life full of adventure - whether they’re playing outside or asking for their next snack!

Outside of medicine, Dr. Walters enjoys being actively involved in her church community, where her family has found sweet fellowship and connection. In her free time, she loves running, playing the drums, traveling, and participating in medical mission trips when opportunities arise.

She feels honored to care for children and families in the community and looks forward to building lasting relationships with each family she serves.

Dr. Willard earned his undergraduate degree from Washington and Lee University in Lexington, Virginia, before receiving his medical degree from the University of South Carolina School of Medicine in Columbia, South Carolina. He completed his internship and residency training through the University of South Carolina School of Medicine and Palmetto Health Richland Memorial Hospital in Columbia.

Outside of the office, Dr. Willard enjoys spending time with his family, traveling, and being outdoors - especially fishing whenever he gets the chance.
