Lindsay Arnold Cusick, born January 11, 1994, in Provo, Utah, is an American professional dancer, choreographer, and entrepreneur who has become one of the most recognizable faces in competitive ballroom dance on television. Specializing in Latin and ballroom styles, Arnold first captured national attention as a contestant on the ninth season of the reality competition series So You Think You Can Dance, where her technical prowess and vibrant stage presence distinguished her among a field of elite young performers. That early exposure served as a springboard for a career that would soon place her in the living rooms of millions of viewers across the country.

Arnold’s ascent to mainstream fame began in 2013 when she joined the professional cast of Dancing with the Stars, making history as one of the youngest pros ever to compete on the long-running ABC hit. Her arrival marked the start of a remarkable tenure defined by versatility, resilience, and an uncanny ability to elevate her celebrity partners. Over the years, she partnered with a diverse array of personalities, including Carlos PenaVega, David Ross, and Mark Ballas’s frequent collaborators, but her crowning achievement came in season twenty-five when she teamed with singer-actor Jordan Fisher. The pair delivered a dominant run that culminated in a victory, and Arnold set a record that season by earning nine perfect scores, the most ever achieved by a single couple in the show’s history. That milestone cemented her legacy as one of the most decorated and consistent performers in the franchise.

Beyond her competitive triumphs, Arnold has expanded her influence into choreography and business. She has lent her creative expertise to numerous live tours and specials associated with Dancing with the Stars, and she has developed a strong presence as a social media influencer and fitness advocate, sharing dance tutorials and lifestyle content with a devoted following. In 2021, she co-founded a dancewear and activewear line, channeling her professional insight into designs aimed at dancers of all levels. Her entrepreneurial ventures reflect a broader ambition to make dance accessible and celebrated beyond the ballroom floor.

Arnold’s personal life has also been a point of connection with her fans. She married her high school sweetheart, Samuel Cusick, in 2015, and the couple has since welcomed two daughters. Balancing the demands of a high-profile television career with motherhood, she has spoken openly about the challenges and joys of navigating both worlds. While she has stepped back from full-time competition in recent seasons to focus on her family and business pursuits, she remains an influential figure in the dance community, frequently returning to Dancing with the Stars as a guest choreographer and mentor. Her journey from a young contestant on So You Think You Can Dance to a record-setting professional and entrepreneur stands as a testament to her talent, work ethic, and enduring appeal in the entertainment industry.
