For the first ten years of her career, Dr. Nelson worked in the academic practice at Children’s Memorial Hospital. There she established herself as an expert in pediatric gastroesophageal reflux disease (GERD) publishing many papers on that subject. She also was a leader in understanding dietary treatments for eosinophilic esophagitis.
