Maen started his artistic journey with the Fayhaa Choir and did that for nine years where he won 1st place at the Group Singing Festival for Best Chorus and Best Maestro.
He sang Mouwachahat as a soloist with the chorus and performed at several regional and international festivals in more than 25 countries around the world.
A milestone of his career, Maen was the first person to perform the Azan alongside Ave Maria with soprano Tania Kassis at the Union Prayer. Kicking off in Paris first, he later performed in Milano, Italy at St. Duomo Cathedral's courtyard by request from the Pope himself.
