In 1994 Steliana began training in gymnastics. Her first coach was Raluca Bugner (who also coached Sabina Cojocar). Steliana showed great talent and aptitude for gymnastics and quickly advanced to elite level.

In 2002 she joined the national team at Deva and began being trained by Nicolae Forminte (who previously trained Olympic medalist Simona Amanar).
