Get to Know Me

I have been practicing pediatric anesthesiology at Nemours/Alfred I. duPont Hospital for Children for 23 years. I was awarded the Best Anesthesiologist Award in 2006, and I also became a full professor of anesthesiology and pediatrics in 2010. In my personal life, my husband is a retired civil engineer, and I have a son who majored in physics and business in college, and is now starting down his own path in medicine.

Why I Treat Children

If there was a group of people who, above all others, always deserve the highest levels of care, wouldn't it be children? Returning joy to the innocent lives of children has been my motivation as a doctor for over twenty years, and it will continue to be for the rest of my career. Take it from me, there is no better place to make sadness and tears transform into happiness and laughter than a hospital for children.

What I'm Passionate About

As a physician, I believe that I have a responsibility to care for the whole person, not just the injury or illness. My goal every day is to return my patients not only to a state of health through medical science, but also to a state of happiness through compassion. This goal extends to the parents and families of my patients as well, since their emotions often suffer just as much as their children's, if not more so.

How I Try to Make A Difference

Although the primary objective of a physician should be to care for the patients of today, a career full of experience and training in medicine also yields the opportunity to make a difference for the patients of tomorrow through clinical research and mentoring. With this mindset, I have dedicated a large portion of my career to investigative work aimed at advancing the practice of anesthesiology. I also love the opportunity to bring undergraduate premedical students into the OR with me to give them their first glimpse of how amazing a career in medicine can be.
