Meet our little hero

A Mighty Heart. A Mighty Hope.

Mack was born with a congenital heart defect. Today, while he waits for a transplant at St. Laurie Children's Hospital, he reminds us all what real superpowers look like: courage, kindness, and never giving up.

Mack's Story

01

Born a Fighter

Mack came into the world with a rare congenital heart defect called hypoplastic left heart syndrome. From his very first breath, he showed us he was here to fight.

02

The Cape Comes On

Already brave beyond his years, Mack has faced open-heart surgery before his first birthday. The doctors and nurses at St. Laurie's call him their "littlest superhero" — and the name stuck.

03

Waiting for a Miracle

Today, Mack is on the heart transplant list. While he waits, he giggles, he babbles, he grips every nurse's finger with a mighty grip, and he reminds his whole family that hope is a superpower too.

"

He doesn't ask why me. He asks who's next — so he can cheer them on.

— Mack's mom, Erika

St. Laurie Children's Hospital

For more than a year, Mack has spent most of his days at St. Laurie Children's Hospital — a place where superheroes wear scrubs, the IV poles have names, and every hallway has a story worth telling.

The cardiac team at St. Laurie's has become Mack's extended family. The nurses know exactly how he likes to be rocked to sleep. The child-life specialists know which lullabies calm him during an echocardiogram. The doctors know that no medical chart can capture how big this little kid's heart really is.

A portion of every dollar raised by The Mighty Mack Foundation goes directly back to St. Laurie's pediatric cardiology program — so the next family that walks through those doors finds the same incredible care that has carried Mack this far.
