Breakthrough
In April 2003 she joined Topzwemmen Amsterdam (TZA) to train as a full-time professional under the guidance of Fedor Hes. At the 2003 World Aquatics Championships it turned out to be a great decision as she reached two individual finals in the 50 m freestyle ending 7th, and in the 100 m freestyle finishing 8th. In Barcelona she also reached the final in all relay events but did not win a medal. In December she participated in the European Short Course Swimming Championships 2003 where she won her first international titles in the 50 m freestyle and the 4×50 m freestyle.

She was the anchor lady in the 4×100 m medley, she took over from de Bruijn who swam the butterfly leg, finishing 6th. At the end of 2004 she became Amsterdam Sportswoman of the year.
Post-Athens season

The European Short Course Swimming Championships 2005 were very successful for Veldhuis.
