After studying music education, Sergej decided to study singing at the Music Academy in Ljubljana, where he majored in the class of prof. Barbara Jernejčič Fürst.

Alongside his studies he additionally attended seminars - in Slovenia and across Europe - that featured world renowned singing instructors (R. Miller, M. Keenze, M. Lipovšek, C. Spencer…).

He performed as Bastien in Mozart’s opera Bastien and Bastienna. As a 26-year old he debuted in the first premier performance of the opera Poet and rebel in the SNG Maribor, which was composed by Tomaž Svete. He appeared as the lead guard.

He also worked with the RTV Slovenia orchestra and accepted the invitation of Jure Ivanušič to cooperate in the production of the documentary ‘Who wants to be Mozart’.

The public got to know him - along with soprano Petra Turk - as a contestant and finalist of the show Slovenia’s got Talent. As of date they are artistically introducing themselves under the name Petra and Sergej. They added to their classical repertoire by introducing a colorful palette of material from musicals and the crossover program.

Sergej is a founder of successful singing school Orfeus which is located in Bistrica castle in Slovenska Bistrica. As the founder he demands hard work, dedication and love for singing from his students, which is visible also in their successes - live performances and appearances on many festivals across Europe.
