"Patient safety is most important to me. When I’m working with children and their families, I use a calm, thoughtful manner."

My Biography & Research


My patients mean the world to me and I have dedicated my life to hopefully improving theirs.

As a pediatric surgeon, I specialize in liver and kidney transplantation and hepatobiliary surgery. I focus on using minimally invasive surgery to treat my patients.

Patient safety is most important to me. When I’m working with children and their families, I use a calm, thoughtful manner.

I became a pediatric surgeon because I really enjoy both working with kids and performing surgery.

In my free time, I’m an avid rower and do CrossFit several times a week.
