Yulia Zagoruychenko (born September 11, 1981) is originally from Russia where she began dancing at the early age of four. As a child, she enjoyed watching and copying dancers on TV so her mother agreed to take her to dance classes where she did folk dancing for four years. She then moved into ballroom dancing. At the age of 11, Zagoruychenko started to teach kids to earn some money which she then gave to her parents. For financial reasons, she could not afford to dance both Ballroom and Latin and so at the age of 16 she chose to pursue Latin, but when she was 21 she decided to move to America. With her previous partner Maxim Kozhevnikov, Zagoruychenko became the US National Professional Champion and shortly after that, she began dancing with Riccardo Cocchi.

Currently Zagoruychenko and her partner, Riccardo Cocchi, are World Latin Professional Champions and 3-times undefeated US National Professional Latin Champions.
