Alexei Yagudin
Joubert kept his training base in Poitiers throughout his career, in order to remain close to his family. He trained for 15 years with Veronique Guyon, until she resigned from her position in the summer of 2003 to spend more time with her family. Joubert then started training with Laurent Depouilly, and took on Alexei Yagudin as an 'advisor'. Joubert later parted ways with Yagudin because of Yagudin's dislike for Nikolai Morozov, Joubert's choreographer at the time.
