Meet the Staff

Dr. Suzanne Nelson

Dr. Nelson is a graduate of Northwestern Medical School and did her pediatric training at Children’s Memorial Hospital in Chicago. She completed her fellowship training in Gastroenterology, Hepatology and Nutrition at Boston’s Children’s Hospital and Massachusetts General Hospital at Harvard Medical School. She also received a Master’s of Public Health at the Harvard School of Public Health.

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 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 eosinophillic esophagitis.

In 2004 Dr. Nelson began solo private practice and founded Children’s Gastroenterology Specialists. She made this change so she could have more control over caring for her patients giving them the best medical care possible. In 2017 she joined Pediatrust so that she could relieve herself from the business aspects of her practice and focus on her clinical practice. She continues to serve on staff at both Lurie Children’s Hospital and Evanston Hospital. She is an Assistant Professor of Clinical Pediatrics at the Feinberg School of Medicine.

While in private practice she has continued to publish papers on GERD, eosinophillic esophagitis and inflammatory bowel disease. She recently co-authored of the book Cooking for your Gluten Free Teen : Everyday Foods the Whole Family will Love (Andrews McMeel Publishing, LLC, 2013).

Dr Nelson is married and has two wonderful daughters as well as two somewhat naughty cats. She enjoys working out, travelling and going to the theatre.
