Get to Know Me

I spent much of my career in the military. My wife is an elementary school teacher, and has an enthusiasm for kids that rubbed off on me, and I went into medicine because I wanted my work to benefit people directly as well. I started out as a general pediatrician, and specialized in pathology. My field gives me plenty of chances to improve care for children.

Why I Treat Children

I started out as a general pediatrician and enjoyed working directly with children and families. Today, as a pathologist I’m in a more behind-the-scenes role – I still enjoy being part of a medical team that improves lives for children.

What I'm Passionate About

Medical care should be delivered as seamlessly as possible, and that includes lab work. We can learn a lot from patients and their families. By asking the right questions, we can continuously improve the scientific processes of lab work – so it’s easier for patients, and doctors receive vital information quickly and reliably.

How I Try to Make A Difference

I think it’s important to keep patients and families at the center of everything we do. In the lab, I try to make things as comfortable and convenient as I can. I also design our techniques to get important results to doctors quickly, so they can provide better care based on information they need to make treatment decisions.
