When Brianna was in preschool, a gym would hold mobile classes at the school, Brianna loved them so much that she started asking her parents if she could be enrolled in gymnastics. A few years later in an after school program, Brianna saw a girl hanging on the bars and asked her how she learned to do that. She said that she was taking gymnastics class and from there Brianna continued to beg her parents to enroll her. They finally gave in. In 2009 at the age of six, Brianna was enrolled in the recreational classes at Island Tumblers Gymnastics. She tried out for the competitive team later that year and started the team program in January of 2010.

As a level 7 gymnast in 2014, Brianna earned gold medals on uneven bars, balance beam and in the all-around with a 37.575 at the State Championships. She qualified and placed second in the all-around, first on uneven bars and second on floor exercise at the Region 2 Championships. In 2015, she placed fourth in the all-around, third on uneven bars and fourth on balance beam at the State Championships, qualifying to Regionals. Brianna competed level 9 for the next three seasons where she qualified to the Level 9 Western Nationals in 2017 and 2018. At the 2017 Region 2 Championships, she placed fourth on floor exercise and sixth in the all-around. In 2018, Brianna won the uneven bars, floor exercise and all-around titles at the State Championships. At the Region 2 Championships, she finished third in the all-around and second on floor exercise. She had a good meet at the 2018 Level 9 Western Nationals in Salt Lake City, UT where she placed 13th overall and 10th on balance beam. Brianna was unable to compete in 2019 due to a knee injury.

When Brianna is not training 20 hours each week in the gym, she enjoys hanging out with her friends, going to the beach and playing/snuggling with her dog named Princess. She is an honor student at Myron B. Thompson Academy. Brianna also coaches at the gym on her days off from practice. She really enjoys working with the kids because she gets to help them reach their goals like her coaches helped Brianna to achieve hers.
