The League of Heroes

Meet the Team.

Every superhero needs a team. Mack has the best one in the business — the doctors, nurses, and surgeons of Lurie Children's Hospital. Here's everyone who makes Mack's mighty story possible.

The

Doctor

Mack's primary cardiologist. Patient, brilliant, and the steady voice his family leans on every time test results come back. Has answered the words "but what does that mean?" more times than he can count — always with a smile.

Cardiology 12+ years Endless patience

The

Nurse

The reason Mack laughs more days than he cries. She knows exactly how he likes to be rocked, which lullabies calm him before a check-up, and which stuffed animal needs to come along for every blood draw.

The

Surgeon

The steady hands behind Mack's open-heart surgery. Trains other pediatric cardiac surgeons across the country, but never feels prouder than when one of her little patients walks out of Lurie's healthier than they walked in.

Mighty Mack

One year old. One mighty heart. One blue suit, one red cape, and a grin that has earned him fans across the entire cardiac ward. Currently awaiting his transplant — and proving every day that the smallest heroes can be the bravest of all.
