Oleg Mirochnikov is native Russian born in Minsk, Belarus. He was professionally trained as an actor at the Belarusian Academy of Theatre and Art. After his graduation, he worked extensively as an actor in theatre and films in Russia, and served as a radio and television host and presenter on various shows and programmes. In the early 1990s, Oleg moved westward, first to Belgium and then to England. He is based in London. In addition to being an actor, he is also a director, voice-over artist, acting coach, as well as a Russian dialogue/dialect coach.

As an acting coach and tutor, Oleg has trained Michael Fassbender, Tom Hardy, Russell Brand, Emilia Clarke, Gwendoline Christie, and Regé-Jean Page. His acting methods and coaching style are unique and draw equally from the three great Russian masters: Stanislavski, Meyerhold, and Vakhtangov.

Oleg has more than twenty years of experience as a voice-over actor and Russian dialogue/dialect coach. As a Russian dialogue/dialect coach, he has worked on many acclaimed projects and coached such high-profile actors and performers such as Kevin Bacon and Daniel Craig.

Oleg continues to coach both in acting and in Russian dialogue/dialect and provide actors with invaluable skills and insights to better perform their roles. He works on- and off-set as well as privately with actors on their film and television role preparations and script analysis. Oleg's own burgeoning acting work as a character actor on film and television allows him the intimate insight on the workings of an actor and all the essentials needed to create a stellar and truthful performance on-screen.
