When he was studying at the conservatory, he took part in the Keshet Eilon Summer Mastercourses in Israel, under the guidance of Ida Haendel and Shlomo Mintz.

Furthermore, the young violinist had started playing in the Moscovia Chamber Orchestra and consequently passed all stages up to the concertmaster position.

He also took courses outside Russia, particularly by Augustin Dumay in the Queen Elisabeth Music Chapel, and by Ana Chumachenco in the Kronberg Academy.

In Belgium Boriso-Glebsky was given for performing the violin II Patti by Antonio Stradivari that let him take part in prestigious contests further.

Boriso-Glebsky has also performed works from many musicians of the twentieth century, including Benjamin Britten, Sergei Prokofiev, and Béla Bartók.
