Why I Treat Children

I’ve always loved kids, their naturally inquisitive nature, and the potential that every child has. I knew I wanted a career that serves others, that’s why my work as an orthopedic surgeon is a perfect fit. I get to help children with orthopedic disabilities regain as much of their mobility, and restore as much normal functioning as possible.
