Get to Know Me

I’ve been a pediatrician long enough to see patients grow up and bring their own children to me. My experience helped us become a designated “medical home” for children with complex issues. My wife and I raised three children in the community where I practice. We have all worked hard to make this a good place to live and thrive.

Why I Treat Children

When you treat a child, you are really caring for the whole family. The wellness of the group depends on the health of each of its members. Similarly, the community is stronger when families are healthy and happy. So I take my work very seriously, giving patients and their families love and compassion in every situation.

What I'm Passionate About

I’m passionate about providing high-quality care for my patients, no matter what their needs are. Our practice has been designated a medical home by the American Academy of Pediatrics. At the time we earned it, there were fewer than 25 practices in Florida with this designation. It means that we have demonstrated the ability to care for children with complex illnesses and conditions as well as children who just need wellness checks and vaccinations.

How I Try to Make A Difference

As a seasoned pediatrician with more than 25 years of experience treating children and teens with a wide variety of conditions, including behavioral and developmental issues, I am dedicated to finding answers for them and their families. I also care deeply about my community. I serve on the board of Boys Town and am active in other organizations that are doing good work for children and families in Central Florida.
