Four-year-old Nash Norris' face lit up as he was lifted off his mother's lap and placed on the ground next to the red Corvette.

Nash lifted his arm and waved to the crowd cheering to him in front of Keller Williams Reality in Chattanooga.

A homemade red banner hung across the door saying, "Welcome to Nash's Wish Party."

Nash like other little boys was distracted by the bright colors and balloons and ignored his mother's voice. But as he stood up, he didn't have the strength to lift his head straight.

"He's the most amazing little boy in the world," said his mother, Robin Norris. "He's got this great big smile that fills his whole face."

Nash was born with cancer on his spinal cord, and his condition has worsened over his short life, Ms. Norris said. The Norris family first noticed something was wrong when he was 15 months old and he couldn't crawl, she said.

But Nash didn't seem to notice his condition, he just smiled as his brother picked him up and carried him inside for his party.

The party was thrown by Keller Williams workers who had raised $7,000 for the Make-A-Wish Foundation, and he was the child chosen to have his wish fulfilled.

Because of Nash's love for killer whales, his wish was to eat lunch with Shamu, his mother said.

"He loves 'Free Willy,'" Ms. Norris said. "He'll look at National Geographic books with killer whales -- it doesn't have to be kid books."

Nash has two whale dolls that he carries around, said his 16-year-old brother, Walker Norris.

"He takes it wherever he goes," Walker said.

With teary eyes, Walker looked around the room full of family, friends and Keller Williams staff members.

"It's really overwhelming," he said.

The room was decorated to look like an under-the-ocean scene with blue paper taped to the walls and creatures including whales hanging from the ceiling.

Nash was presented a book that showed all the places he would get to visit next week, including Sea World and Disney World. The agency also gave him toys for the plane ride and presented his parents a check for $1,368.

When asked what his favorite part of the day was, he laughed and said, "Everything!"

Last year, company workers decided they wanted to grant a full wish for a child, said Robben Mathews the team leader for the agency.

About 40 or 50 employees walked a race in November to raise the money, Ms. Mathews said. The workers then were told they would get to throw the child a party.

Make-A-Wish Foundation

Since 1980, the Make-A-Wish Foundation has enriched the lives of children with life-threatening medical conditions through its wish-granting work. The foundation's mission reflects the life-changing impact that a Make-A-Wish experience has on children, families, referral sources, donors, sponsors and entire communities.

"We had thought we would get to do this in 2010, but we got a call from Nash's doctor saying we needed to do it in the next three weeks," Ms. Mathews said through tears.

As Nash left the room to go for another ride in his favorite kind of vehicle, the red convertible, the staff was in tears for the opportunity to make a little boy's dream come true.

"He's been through a lot," said his father, Jimmy Norris. "But he handles it like a trooper. He's the toughest guy I know ... he's made me tougher."
