Daniel Mallon, MD, MSHPEd



As a pediatric gastroenterologist, I care for children with celiac disease, constipation, functional gastrointestinal disorders and inflammatory bowel disease. I serve as the co-director of the Celiac Disease/Type 1 Diabetes Clinic at Cincinnati Children’s Hospital Medical Center.

The most helpful information in diagnosing a gastroenterology condition comes from what my patient and their family tell me, so I listen carefully. I have experience and expertise in medicine and separating fact from fiction regarding various diets, tests and treatments. Parents are the experts when it comes to their children. Together, we share our knowledge to make a difference in their child’s life.

I love combining science and helping people directly. Being a physician lets me do this and to form close, long-lasting relationships with patients and families. Belly pain, difficulties with eating and waste removal are so disruptive to the lives of children and their families. It’s a challenge to figure out what’s causing the child’s condition. When we find the answers, and when my patients get better, it is so gratifying.

In my academic work, I teach and train pediatric residents and pediatric gastroenterology fellows to provide the best care possible.

My research focuses on medical education and celiac disease. I’m improving online learning platforms so general pediatricians and subspecialty trainees can learn advanced content on their own time.

Our team participates with several other children's hospitals to investigate standardized questionnaires for celiac disease to help doctors, dietitians and families assess a child’s risk for gluten exposure. We're studying the best ways to identify and care for children with both type 1 diabetes and celiac disease.

When I’m not at work, I spend time with my wife and three small children, watch Cincinnati Reds baseball games and explore Cincinnati by running and cycling.
