Fethon Miozzi was born in Rome and trained at the National Academy of Dance, but after graduating in 1990, he moved to study at the Agrippina Vaganova Choreographic Institute in St. Petersburg. He soon became a dancer at the Mariinsky Theatre and quickly rose to fame on the Russian ballet scene.

In 1993, he was awarded the Leonide Massine Prize in Italy. In 1997, he received the Danzasì Prize for his physical and artistic talent, and in 1998 he won the Danza & Danza Award as the best Italian dancer in the world.

He studied under some of the greatest stars of Russian ballet: Konstantin Sergeyev, Natalia Dudinskaya, V. Semionov, M. Daukaev, T. Fesenko, Liudmila Kovaleva, N. Pavlova, and Makhar Vaziev. He performed the leading roles in the classical ballet repertoire and had an exemplary career in Russia—preceding by about twenty years the equally brilliant rise of Jacopo Tissi, now at the Bolshoi Theatre.

In 2008, Altynai Asylmuratova, then director of the Vaganova Academy, entrusted him with the position of Classical Dance teacher—a position he still holds. He is the only Italian, since the time of Cecchetti, to have taught continuously at such a prestigious school in Russia.

In Russia, he is also known as Fyodor Ivanovich, and many of his students—now professional dancers—consider him one of the best teachers in the world: demanding yet cheerful, always ready to support his students.
