Career

Carpentry Caldiero is a carpenter by trade. He started climbing at the age of 15, and bouldering at 17, and specializes in highball bouldering.

In season six, Caldiero performed well enough to again advance to the National Finals. He was able to complete Stage 1 of the Finals course, but failed on Stage 2's Double Salmon Ladder, ending his season. Britten and Caldiero both completed the Stage 4 rope climb in the allotted time; Britten ran first, while Caldiero ran second and completed the Stage with a faster time. Because Caldiero's climb was faster, he was declared the season's official winner, Because Britten ran first, however, some fans and competitors considered him to be the "first American Ninja Warrior"; Joe Moravsky stated: "In my opinion, Geoff is technically the first American Ninja Warrior and Isaac is the second. The only difference is Isaac climbed it faster so he gets the million and won the season." Instead, he served as a spokesman for the series and its sponsor, POM Wonderful. It was revealed that he would make a return to Ninja Warrior by participating in the celebrity special of Ninja Warrior Germany in November 2017.

On April 24, 2018, Caldiero confirmed he would come out of retirement to compete in season ten of Ninja Warrior in the Indianapolis region. While he cleared the qualifying course, he fell early in the Indianapolis city finals and was unable to qualify for the National Finals in Las Vegas.
