Katherine was born in Madisonville, Kentucky, on December 9, 1994. As a young teenager and student at Madisonville North Hopkins High School, she won her hometown pageant in 2009, garnering the title of Hopkins County Junior Miss. She also studied piano since the age of ten.
After her high school graduation, Katherine enrolled in the University of Alabama, where she earned her bachelors degree in international relations, cum laude. Following her college graduation, she enrolled in a masters program at the University of Nevada. While there, she was crowned Miss Summerlin (2015), and in June of that same year she captured the title of Miss Nevada. With a GPA of 4.0, Katherine was also honored with an Outstanding Academic Achievement Award.
Despite impressing pageant judges and the audience with her classical piano performance, Katherine has said, “I don’t think I want to be a professional musician. I am a teacher in North Las Vegas. I’ve always had a love of mathematics, and I want to continue teaching it. So many students don’t love it,
Katherine's win as Miss Nevada qualified her to enter the Miss America Pageant last September. In that competition, the crown went to Miss Georgia, Betty Cantrell.
