Julien offers private piano lessons via video and a video course program. Specializing in Blues Jazz and New Orleans piano, he trained at the source in New Orleans, New York directly with pianists such as Aaron Goldberg, Georges Cables, Jay Bianchi or Junior Mance. He also studied at the Bill Evans Piano Academy in Paris.

His main approach is based on the study of fundamentals, rhythm, harmony and improvisation to quickly enjoy playing and create a work routine related to the objective of each student.
