For Dr. Ricardo Pun-Chong, being a physician isn't just about treating patients -- it's about how you care for their families.
As a doctor undergoing his medical training in Lima, Peru, Pun-Chong treated many children who traveled with their parents from rural parts of the country. And for most, it's a dangerous journey -- over mountains, across rivers and along unsafe roads, all for medical treatment.
Once in Lima, far from home and often unable to afford lengthy hotel stays, Pun-Chong saw many families forced to curl up on the hospital floors.
"I couldn't get the picture of the families sleeping on the floor out of my mind," Pun-Chong told CNN earlier this year. "So, I decided to do something for them."
On Sunday night, Pun-Chong was named the 2018 CNN Hero of the Year for his efforts to provide free housing, meals and support for sick children and their families while they undergo treatment. The award is determined by online voters who selected Pun-Chong from among the Top 10 CNN Heroes finalists.
In 2008, he founded a shelter and a nonprofit called Inspira and to date, his organization has helped more than 800 families. The shelter was designed to make the children feel at home and to provide a space for kids to "be kids."
Pun-Chong will receive $100,000 to grow his cause. All of the top 10 CNN Heroes for 2018 will receive a $10,000 cash award, and donations made to each of their nonprofit organizations are also being matched up to $50,000.
"We can start building our new shelter with this -- with this prize, we can triple our assistance," Pun-Chong said. "Thank you so much CNN -- thank you so much everybody."
He was presented with the Hero of the Year award by hosts Anderson Cooper and Kelly Ripa.
"The real heroes are our kids," Pun-Chong said. "Infinite thank yous to each one of you for trusting us and showing us that love has no borders."
Sunday's CNN Heroes Top 10 tribute show was chock full of stars and good vibes, laughs and some tears -- but only the happy kind.
Ripa and Cooper emceed the show from New York's American Museum of Natural History, and Grammy Award winner Lenny Kravitz got the crowd moving by performing the song "Here to Love" from his album "Raise Vibration."
Will Ferrell, Bryan Cranston, Danai Gurira, John C. Reilly and Ted Danson were among the stars in attendance. And even Sully, former President George H.W. Bush's service dog, was on hand ... err, paw ... to celebrate an incredible cast of everyday heroes.
Here's how the rest of the top 10 CNN Heroes are changing lives in their communities:
- Abisoye Ajayi-Akinfolarin, a computer programmer in Lagos, Nigeria, teaches impoverished women in the city's slums how to code through a program run by the Pearls Africa Foundation.

Beginning at 8 p.m. ET on Sunday, December 9, donations made to the designated nonprofit organization of each Top 10 CNN Hero, via CNNHeroes.com and crowdrise.com/cnnheroes, will be matched by Subaru up to $50,000 per Hero through January 2, 2019.
