Serhii Kachura was born in Mykolaiv, Ukraine. He began dancing in the "Rhythms of the Planet" group, which was led by Vasyl and Iryna Pak at that time. After seven months of training, the instructors convinced his parents to enroll Serhii in the Kyiv State Choreographic School.

After graduating from the school in 2005, Serhii began working at the Kyiv Municipal Academic Theater for Children and Youth, where his artistic journey started with the corps de ballet and minor roles. After a year at this theater, Serhii moved to Lviv.

At the Lviv Opera, Serhii advanced from a corps de ballet dancer to a Merited Artist of Ukraine, becoming a leading stage performer. It was here that he met his partner on stage and in life, Viktoriia Tkach. Alongside his work in the theater, he continued his education and refined his skills as a choreographer. Serhii graduated from Ivan Franko National University of Lviv and Taras Shevchenko National University of Luhansk, earning a master's degree in choreography.

During his time in Lviv, Serhii and his wife created the ballet "Snow White and the Seven Dwarfs" to the music of Bohdan Pavlovskyi, and they also worked on choreographic pieces in dramatic theaters. Thanks to the general director of the Lviv Opera, Vasyl Vovkun, choreographic episodes and a short chamber ballet were staged in the Mirror Hall of the Lviv Opera.

Throughout his creative career, Serhii visited many countries as both an artist and a tour organizer. As a true professional, he has mastered the entire process of creating choreographic performances, thanks to fruitful collaborations with artists, musicians, actors, and singers. Serhii meticulously remembered all the processes that occur in the theater during the creation and production of performances. With significant experience in staging performances, Serhii began organizing his own projects involving ballet dancers, musicians, and singers in various European countries.
