This weekend, you can take action for the more than 2.5 million people in this country who are living with congenital heart disease.
On Sunday, it's the annual Walk for 1 in 100, helping to raise money for the Adult Congenital Heart Association.
Check-in opens at 9 a.m. Sunday at Tempe Diablo Stadium.
Ahead of the big day, ABC15 spoke with Isie Vierthaler, a junior at Perry High School in Gilbert, who is living with congenital heart disease.
Despite some physical challenges, Isie has never let anything stop her - and she's hoping to spread that same positivity to others in the community. She's been a longtime participant and volunteer for the Walk for 1 in 100.
"It makes me feel like I've accomplished something," she says. "It gives me a sense of pride that I'm still here doing stuff that I'm doing and not caring what people think because of it and getting stuff done that I want to accomplish, actually done and accomplished."
