Rozmajzl began her pageant journey in 2015 when she registered for the Miss Georgia USA and Teen USA pageant. She was named a Top 15 semi-finalist.
Determined to win the crown, Rozmajzl returned for her third try at the Miss Georgia Teen USA title. She registered for the 2016 Miss Georgia USA and Teen USA pageant. Not only did she make the semi-finals, Rozmajzl was named to the Top 5 and walked away as third runner-up.
Rozmajzl then took a year off from the pageant stage. Rozmajzl returned and registered for the 2018 Miss Georgia USA and Teen USA pageant, this time competing as a Miss. On her first try at the Miss title, she was called to the Top 5 and ultimately placed as fourth runner-up.
Encouraged by her strong performance the year before, Rozmajzl registered for the 2019 Miss Georgia USA and Teen USA pageant. This time, the crown was hers. On November 17, 2018 Rozmajzl was crowned Miss Georgia USA 2019 at the Henry County Performing Arts Center located in McDonough, Georgia.
Rozmajzl will go on to represent the state of Georgia at the 2019 Miss USA competition.
