Mackenzie Symanietz is back choreographing on Season 4 of World of Dance after helping her cousins, Ellie & Ava Wagner reach the World Final on Season 3. This season, she is choreographing for the youngest contestant on the show, nine-year-old Savannah Manzel.The "Larkin Legacy" is well-known in the dance industry, thanks to her grandmother Shirley Larkin, who founded Larkin Dance Studio. The studio is now run by her mother, Molly Symanietz. The studio has produced incredible dancers like Ellie & Ava, Taylor Sieve, Madison Jordan and Eva Igo.On this week's aftershow, Manzel describes the incredible Duel against 305 and how Symanietz prepared her for every situation, including a falling microphone pack.
