Tonight, Ainsley Earhardt brought “Hannity” viewers the first installment of the “Great American” series.

John Tartaglio grew up with a passion for sports, playing baseball and football in school. But in 2004, as a senior in high school, his athletic aspirations were crushed when he was diagnosed with an extremely rare bacterial infection.

Doctors had to amputate both of his legs in order to save him.

Tartaglio set the goal to be able to walk at his graduation. Four months later, he did. Then, he set his sights even higher, running a 5K and 10K.

In 2009, he became the first ever double amputee to finish the New York City Marathon without a wheelchair, crossing the finish line in 15 hours and 59 minutes.

All the years of hard work to overcome his disability prepared him for the greatest challenge of all – becoming a husband and father.

Despite all that he has been through, Tartaglio, now 27, said he wouldn’t change a thing.

“I don’t think I would have met the amazing people that I have, I don’t think, I just don’t know if I would have been able to expect as much as I do out of myself without it happening,” he said.

Tartaglio has written a book, entitled “From Tragedy to Triumph,” and is finishing up his MBA.
