Her inspiring story 

19-year-old celebrity dance trainer 

Sienna started dancing when she was around 4 years of age and began choreographing when she was 10! She shifted to L.A. with her mother at the age of 16. At the time, the two did not have enough money to pay their rent. But Sienna’s directors told her to have faith in her skills and that her time was near. And it was!
