From competitive tennis to individual coaching
Andy Dumitrescu started playing tennis at around age five. As a player, he reached the national Top 10 in Romania and, at around 18, qualified for international tournaments at Futures and Challenger level. In Germany, he most recently held a German LK 1 ranking.
He has been passing on this experience as a coach for over ten years. Before founding NDS, he was responsible for running tennis-school operations for several years — experience that now shapes his personal coaching work.
Playing career & coaching experience
His players range from four-year-old beginners to 90-year-old recreational players — Andy has worked with beginners, recreational and competitive players, as well as high-level juniors and advanced players.
During his own career, he trained and worked with professional players, including players ranked around ATP Top 350 and, in some cases, inside the Top 100, as well as German junior players ranked around Top 50–100 nationally in their age category.
As coach of a U18 junior team, he led the team to the TVM championship two years in a row.
“Every player should leave every session better than when they arrived.”
Andy works highly individually. His goal is to quickly identify the underlying causes of technical and movement issues — not just treat the symptoms.
His approach considers body mechanics and kinematic movement chains, rather than relying only on generic technical cues. He still uses conventional technical instruction where it's the right tool.
Training is informed by modern principles found in today's high-performance tennis.
