Born in Jackson, Wyoming, Johnson grew up in nearby Victor, Idaho, and made her World Cup debut in December 2015. In her first World Cup season in 2017, she finished eighteenth in the downhill standings. At the World Cup finals in March at Aspen, Johnson crashed in the downhill and suffered a tibial plateau fracture to her left leg.[4][5] Johnson quickly recovered from this injury and in the 2018 season she finished eleventh in the downhill standings and competed in the Winter Olympics, finishing seventh in the downhill and fourteenth in the super-G.
She returned to the World Cup circuit in January 2020 with a 25th in the downhill at Altenmarkt and consecutive top tens at Bansko. Her first World Cup podium came in December 2020 at a downhill in Val d'Isère, France.
She qualified to represent the United States at the 2022 Winter Olympics,[8] but was injured and did not compete.
When turned 18, Johnson legally changed her first name from Breanna to Breezy, her long-time nickname which combines her given name and the word freezy.[9] She came out as bisexual in 2022.[10]
