His career began when Grigoryan studied at the Metro Theatre Children's Studio (1995–1997).

Also in 2011 a very spontaneous shooting turned into a real success: Lilit Movsisyan and Grigoryan made an experimental short (starring Grigoryan) which was used in Ridley Scott's Life in a Day Scott project in the opening part of the film.

From 2013 Grigoryan took acting courses overseas, at Anthony Meindl's Actor Workshop, and The William Esper Studio studying the Meisner technique.

Grigoryan is also well known for his music videos, performing as a singer, director and producer.

In 2018, during her interview on Nice Evening, she said that the song is in Spanish, and it is written by Vahram Petrosyan and Arthur Abgar.
