get to know me

I chose my specialty because...

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, chronic conditions. And talking with kids about pooping keeps you from taking yourself too seriously!

I chose to work at Dayton Children's because...

I was attracted by a well-established team of outstanding individuals who are committed to the care of kids with digestive disorders and are well supported by the institution.

Dayton Children's is special because...

of the commitment of the people who work here to care for our kids.

Dayton Survey

Dr. Bates has been a great provider during a very difficult time for our son and family. He has been patient and very accommodating when treating a not-always-so-willing patient. Dr. Bates has answered every question with confidence and knowledge. I can't thank him and his team enough for finding the cause of my son's stomach pain and helping us get back on track with life!
