Dr. Bates has been chief of the division of pediatric gastroenterology and nutrition at Dayton Children's Hospital since 2015. He has been named one of the Best Doctors in America - a doctor that other doctors trust the most - multiple times, including in 2019. He came to Dayton from Mission Children's Specialists of Asheville, North Carolina. But he's no stranger to the Buckeye state. He received his pediatric and pediatric gastroenterology training at Cincinnati Children's Hospital Medical Center and was then a faculty member there for 10 years. Dr. Bates earned his bachelor of science, medical degree, and PhD at Duke University. He has more than 40 papers and chapters in peer reviewed journals and textbooks and has had research funded by the National Institutes of Health. Dr. Bates has special interests in treating children with congenital and genetic disorders of the digestive system and celiac disease. When asked why he chose to specialize in pediatric gastroenterology he responded, "I enjoy the breadth of pediatric gastroenterology. We see patients of all ages with conditions ranging from relatively simple and self-limited to very complex, chronis conditions. And talking with kids about pooping keeps you from taking yourself too seriously!" One of his favorite things about working with children is "their capacity to be a kid no matter what is happening".

Question Rating Breakdown
It would be nice if hours were more appropriate for children who are in school so that they do not have to miss school.
Dr. Bates is calm, supportive, understanding, and listens to all concerns that our family and our child have . We really enjoy having him as our provider.
Dr. Bates is very thorough kind and understanding took a lot of time with us and listened and the result was he did not do a lot of unnecessary tests that I believe may be other doctors would have done we definitely will follow up with him, but we were very impressed with Dr. Bates.
Dr. Bates was good and listened to my questions and answered them, and he's a good provider.
