About Me

As a colon and rectal surgeon, I believe in taking a comprehensive approach to patient care. I provide state-of-the-art treatments and manage long- and short-term factors that affect a patient's overall health and well-being. I specialize in transitional care for patients with congenital colorectal conditions including Hirschsprung’s disease, anorectal malformations and inflammatory bowel disease.

I enjoy the opportunity to collaborate with dedicated teams of health care providers at both The Ohio State University Wexner Medical Center and Nationwide Children's Hospital. Due to our unique partnership, we're able to offer an unprecedented care program that helps children transition through their treatment plans as they grow.

In my spare time I enjoy spending time with my family, jogging, practicing yoga and traveling.

Consulting and Related Relationships

At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.
