McKaylee was enrolled into dance by her mother, who believes dance gives children an outlet to express themselves, learn discipline, confidence, poise, posture, time management, exercise, and technique. McKaylee loves to watch all styles of dance and her favorites to perform are contemporary or lyrical. Her specialties are ballet and contemporary and she has been dancing for twelve years. If McKaylee doesn't become a professional dancer, then she would like to be a marine biologist. Her mother Shari owns True Dance Company.

Her trio performance was strong enough to send her to the second week. McKaylee was placed into the Bleeding Heart trio for the second week. While she was considered the best in her trio, she ended up in the bottom three with her trio. McKaylee was spared because of her technique and then assigned by Ally to be in a trio with her and Tyler. McKaylee makes it onto the next week.
