Timothy John Pirolli, M.D., is a pediatric surgeon who specializes in cardiac and cardiothoracic surgery at Children's Health℠. He cares for both children and adults who were born with heart defects or who have developed heart problems early in life.

“Every day brings new challenges, and it’s exciting to work with a team of doctors and nurses to find new ways to treat our heart patients,” says Dr. Pirolli. “With the right treatment, the majority of our patients can live long, healthy lives.”

Dr. Pirolli serves as Surgical Director of the Adult Congenital Heart Disease Program and as an assistant professor of cardiothoracic surgery at UT Southwestern Medical Center.

Dr. Pirolli earned his medical degree from the University of Pennsylvania School of Medicine in 2008. In 2014, he completed a six-year cardiothoracic surgery residency at Stanford University. In 2015, he completed a fellowship at Children's Hospital in Philadelphia, where he focused on congenital heart surgery.

As a young medical student, Dr. Pirolli was intellectually curious and enjoyed biology and science. Since he also enjoys “fixing things,” being constantly active and thinking on his feet, his decision to become a surgeon seemed like a natural one.

“I felt that if I could combine my love of pediatrics, surgery, and the heart into one career, I would be very satisfied spending the rest of my life taking care of these patients,” says Dr. Pirolli. “And, fortunately, I am able to do that.”

Today, Dr. Pirolli’s clinical areas of interest include pediatric congenital heart disease, adult congenital heart disease, single ventricle heart disease, airway disease and heart transplantation.

When we can make a difference in a family’s future and help a child get better, that’s extremely rewarding.

“When we can make a difference in a family’s future and help a child get better, that’s extremely rewarding,” says Dr. Pirolli.

Spending time with his own family is also important to Dr. Pirolli. He and his wife have a young daughter and two Siberian Huskies who are “fun, hyperactive, family dogs.”

Dr. Pirolli and his wife enjoy concerts – rock and country. And their passion is hiking in the great outdoors – especially in national parks throughout the country.
