Smart’s diving career began at the age of five when she competed in her first diving meet. She instantly fell in love and set her sights on competing in the Olympics. At the age of fifteen, Smart packed her bags, kissed her family goodbye, and moved away from home to train in hopes of making her Dream a reality. Unfortunately, due to a back injury she fell short of her dream but was given the opportunity to dive collegiately at the University of California, Berkeley, where she qualified for NCAA’s and won a National Championship with her team in 2015. She graduated with a degree in Media Studies and then went on to start her Masters in Sport Psychology. Still feeling like she had more to give in the sport of diving, Smart went cliff jumping for the first time and immediately realized that everything up to that point in her life had been preparing her for this. Smart began diving again, but with the intent to be a "high diver." Within a year, Smart became part of Team USA and is currently the youngest high diver representing the United States. She won a Bronze Medal at the 2018 FINA World Cup in Abu Dhabi and became a permanent diver on the 2019 Red Bull Cliff Diving World Series. In addition to her professional diving career, Smart is also a motivational speaker and environmental activist. She founded "The Clean Cliffs Project," in 2017, which aims to prevent plastic pollution worldwide and inspire others to take action through adventure.
