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.

Dr. Bates is a wonderful GI doctor! As a parent, I don't feel rushed during my son's office visits. He answers our questions thoroughly. He even recommends that we call after hours if we have any questions or concerns during evenings or weekends.
