Arts where he had studied, as well as a soloist at the Kharkiv opera theater.
From 1976 to 1983, he sang in Dnipro, and from 1983 onwards, in Kiev. His domain were dramatic roles like German, Radames or Sergej
(Katerina Izmajlova). In 1990, he started teaching again, this time at the Kiev
conservatory, where he was still active in 2021.
