The Chattanooga Fire Department is rallying behind one of their own, and they're doing it in a very big way.
Tristin Greer, 16, the son of senior firefighter Jason Greer, is battling a disease called Neuroblastoma.
Of course, medical bills are through the roof.
That's why the fire department is holding a benefit breakfast and concert for the family.
American Idol finalist Bucky Covington even stopped by.
Covington adds, "The kid's smile just lit me up. It was just amazing how at such a young age, when I was he age I was mad I didn't have my own car yet and kid has so much more to deal with and does it with a smile on his face."
Captain Jeff Eldridge, with the Chattanooga Fire Department, says, "Tugs at my heart to see someone that young struggle with the illness that he's had. That's the reason I came out today."
Last year this event raised more than $3,000 for the Greers, but firefighters hope to raise double that this year.
