LOUISVILLE, Ky. (WDRB) -- Louisville's newest firefighter is just nine years old. So how did the heart of one local fireman help the dreams of a dying young boy come true?

He has the uniform, the badge and even a proclamation from Louisville Mayor Greg Fischer.

The one thing Kevin Olguin may not have is time to enjoy it all.

The 9-year-old boy from Klondike Elementary School who lights up a room with the joy in his face is battling the most aggressive form of brain tumors: Glioblastoma.

Mariela Gonzalez, Olguin's sister, can't help her own tearful emotion when she sees the smile on her brother's face.

"This is how I want to remember him: happy," she said.

"He didn't have any movement on his left side and he struggled talking," said his other sister, Stephanie Gonzalez.

The family says doctors diagnosed him in 2011, and now believe the cancer will steal his young life.

Captain Mark LeMaster quickly forged a friendship with Kevin over their shared desire to battle the flames.

"I work in the schools and I was assigned to his school one day and he came to the office having a bad day not feeling good," Capt. LeMaster recalled.

LeMaster reached out to his Battalion Chief with Louisville Fire and Rescue, just hoping to bring Kevin in for a tour of the station.

It turned into much more: a field trip for his entire third grade class, with Kevin as the star attraction.

"I'm thinking it's impossible," Kevin said. "I think it's like a dream."

"It's so good to know that we have the support of everybody, you know," said Stephanie Gonzalez. "We are not alone...and we're all together fighting for this."

It is a memory that will last Kevin's lifetime...however long that may be.

"I want to say to the firefighter," Kevin said. "Thank you for making this all happen."

We're told the family is covering all of Kevin's medical expenses. If you'd like to help, an account has been set up at any Fifth Third Bank in his name.
