After a year of watching Olivia's big sister in a mommy and me class, Olivia finally was big enough to try gymnastics on her own. What started out as jumping on the trampoline and rolling on the colorful mats, quickly became Olivia's favorite hobby. By the age of six, Olivia was asked to be part of the USAG level 4 gymnastics team. Olivia started her competitive gymnastics career at Port Jefferson Gymnastics. At the 2014 Level 4 State Championships, Olivia placed second in the all-around with a 37.025 and third on vault and balance beam.

Olivia moved up to level 9 for the 2018 season. She placed second in the all-around, fourth on uneven bars and fifth on floor exercise at the State Championships.
