LAKE ASBURY— As 15-year-old Landon Cartwright walked through the gym doors of Lake Asbury Junior High School on Thursday, May 29, he was a rock star. 

Literally. 

With the sounds of his favorite Metallica song blaring through electric guitars, a melodic chorus and thunderous cheers from a full crowd, Cartwright soared through the line of energetic cheerleaders with his arms up and a wide smile.

Cartwright was on his way to receiving a "dream" of a lifetime. 

The school put on the surprise party as part of Dreams Come True — a Jacksonville-based nonprofit aiming to fulfill the dreams of children who are battling life-threatening medical conditions.

Cartwright has Williams Syndrome, a rare genetic neurodevelopmental disorder he was diagnosed with shortly after birth. Amid the chronic pain that comes with his condition, Cartwright continues to keep a positive spirit. 

On June 5, Cartwright and his family will head to Tampa for a five-day trip to see Metallica in concert twice – and meet the band in person with VIP access. Cartwright will also experience the theme-park thrill with tickets to Busch Gardens. 

Seventh grade U.S. history teacher Will Wood is sponsor of the school’s Kids Helping Kids Club, a signature Dreams Come True program that invites children from across the First Coast to champion Dreamers and their families throughout the school year. 

This year was the school’s first time having the club, and Wood said it was amazing that they were able to help one of their own students. 

The club raised $5,000 toward Cartwright's dream through community partnerships and fundraisers. The students also volunteered at non-profit events and helped make special cards for Dreamers. 

“We’re the only club in Clay County at the moment. I’m hoping that changes in future years," Wood said.

In addition to his dream, Cartwright was also presented with other heartfelt gifts, including a signed helmet, shirt and two hats from NASCAR driver Ricky Stenhouse Jr. He also received a Metallica T-shirt and a special guitar decorated by the school’s art club students.

Cartwright said he had a great time at the rally and is excited to live out his ultimate dream.
