Summers began her pageantry career at age ten, having convinced her parents to allow her to compete in pageants when they received a postcard advertisement for a local child beauty pageant. After four years of competing, she won the title of National American Miss Nebraska Junior Teen 2009. She went on to represent Nebraska at the national pageant and was crowned the 2009–2010 National American Miss Junior Teen. In 2012, Summers was crowned Miss Nebraska Teen USA 2012. She represented Nebraska at Miss Teen USA 2012 at Atlantis Paradise Island in Nassau, Bahamas, but was unplaced. At the end of her reign, she crowned Jasmine Fuelberth as her successor. After a hiatus, Summers returned to pageantry and competed in Miss Nebraska USA 2016, where she placed as the second runner-up, losing to Sarah Hollins. In 2018, Summers was crowned Miss Nebraska USA 2018 by Fuelberth, who was the outgoing titleholder. At Miss Nebraska USA 2018, Summers represented Omaha.
Miss USA 2018
After winning Miss Nebraska USA, Summers earned the right to represent Nebraska at Miss USA 2018, held at Hirsch Memorial Coliseum in Shreveport, Louisiana. She won the competition, beating out first runner-upCaelynn Miller-Keyes of North Carolina and second runner-up Carolina Urrea of Nevada, becoming the first woman from Nebraska to win Miss USA. After winning Miss USA, she crowned Bree Coffey as her Miss Nebraska USA successor; pageant protocol states that the two titles cannot be held coterminously as her new Miss USA duties would have interfered with her duties as Miss Nebraska USA. At the national competition, co-host Vanessa Lachey asked the following: "You are on your way to a march where someone hands you a blank sign and a marker. What do you put on your sign and why?" As Miss USA 2018, Summers represented the United States at Miss Universe 2018 in Bangkok, Thailand, where she placed in the top twenty. The eventual winner was Catriona Gray of the Philippines. Summers ended her reign on May 2, 2019, after crowning Cheslie Kryst as Miss USA 2019 in Reno, Nevada.
