Danny Mateo doesn't remember much before he went into cardiac arrest.

"Waking up with tubes and wires and in the hospital. And I wasn't sure what went on," said Mateo.

He and his family live on Maui. They were in Vegas celebrating his retirement after years of working as a councilman and county clerk in his hometown. He and his family were at the LINQ Hotel when things took a turn. Mateo was sitting on a bench when he went down.

Paramedics rushed to the scene. Making first contact with Mateo was Clark County Fire Department Station 32 first year trainee Ding Lawson.

"When I found him he had a pulse and he was actually breathing on his own. And then he woke up and then we gave him some medications, secured his airway for him, and then continued care from security," said Lawson.

After days at Sunrise Hospital, Mateo had one mission -- to reunite with the first responders who saved his life.

"These guys do absolutely incredible. Your Heart Facility Sunrise -- it's gotta be one of the best in the country. Everything that happened to us good and bad there's a lot of good that came out of this," Mateo said.

He says he's forever grateful for the people of Station 32.

"I'm just overwhelmed with gratitude. And thankful that I have a second chance," said Mateo.
