Lakewood Ranch's 15-year-old Lorenzo Liberti makes the flags -- which he sells and donates -- in his garage, using 13 planks of pinewood and working day and night.
The teen has only been producing the "Heroic Flags" for the past eight months, but has already completed 50 and raised thousands of dollars for special needs kids, homeless veterans and the Turning Points nonprofit in Bradenton, Fla., according to WFTS-TV, the local ABC affiliate.
"The encounter made an impression on me," he wrote. "'How could America abandon the [servicemen and servicewomen] who fought for our freedom?', I thought to myself. I wanted to do something about it but wasn't sure how a [14-year-old] boy could make an impact."
Since the COVID-19 pandemic gripped the nation, he has broadened his mission to include honoring medical workers on the front lines of the fight against the disease.
On Thursday, Florida's Department of Health reported another 7,650 coronavirus cases, as well as 120 additional deaths. The Sunshine State's death toll now stands at over 7,700 people.
Using a GoFundMe page, Liberti is raising money to try and place one of his flags in a hospital in every state. He already has a 7-foot flag hanging in the Sarasota Memorial Hospital network where his mother works.
Thus far, the artist has netted almost $8,600 of his $50,000 fundraising goal.
Liberti told WFTS that the effort is "bigger" than him and worries that the day he stops working "is a day that a hero could be forgotten."
"As long as you're living, you're here for a purpose," he said.
