Flaherty was born in Cincinnati, Ohio, United States. In 2008, Charles saved his younger brother's life by donating his bone marrow. His brother, William, was dying from hemophagocytic lymphohistiocytosis; his only chance at living was a bone marrow transplant. Charles, seven at the time, was found to be a match and willingly underwent a three-hour surgery to harvest the marrow which successfully saved his younger brother. In 2010, after a few years of recovery, the family moved to Puerto Rico. Charles was nine years old. He attended St John's School and TASIS Dorado before he switched to Laurel Springs School, an accredited online institution, in 2013. He and his family moved in 2015 from Dorado, Puerto Rico, to Rio Grande, Puerto Rico, and then back to Dorado, Puerto Rico, where he still resides. Flaherty was 13 years old when he began skiing competitively. Watching the 2014 Winter Olympics sparked his interest in taking up the sport. Flaherty trains in Colorado from late October to late April each winter, and returns to Puerto Rico for the summers where he enjoys kitesurfing and swimming in the warm Caribbean waters. He also does a lot of training in Canada and Chile each summer for a few weeks.
Career
Flaherty had to convince the Puerto Rico Olympic Committee to allow him to compete for the country. In 2002, the bobsleigh team that was set to compete for Puerto Rico was withdrawn as one athlete did not meet Puerto Rico Olympic Committee rules about eligibility. After this, the Puerto Rico Olympic Committee withdrew the recognition of the Winter Sports Federation for the territory, effectively ending any hopes for athletes competing at the Winter Olympics. Alpine skier Kristina Krone qualified to represent the territory at both the 2010 and 2014 Winter Olympics in Vancouver and Sochi respectively. However, both times the Puerto Rico Olympic Committee refused to even acknowledge her qualification and the territory did not compete. In December 2017, the Puerto Rico Olympic Committee allowed a six-month temporary membership to the Winter Sports Federation, without funding, thus allowing the territory to compete at the 2018 Games. Although Flaherty was born in the United States, he has resided in Puerto Rico Since 2010, which gave him eligibility to compete for the country. Puerto Rico Olympic Committee’s eligibility requirement is three years of residency on the island.
