The New York Times stated that "Mr. van Veldhoven elicits readings in the best current style, lithe and lithing but also muscular, imaginative and spontaneous". He has been described by NRC Handelsblad as "the top ranking Netherlands choral director", and by Trouw as "one of the few Netherlands early music performers...[with] all-important pioneering zeal".

Jos van Veldhoven is a regular guest artist with international orchestras including Das Orchester der Beethovenhalle Bonn, The Tokyo Philharmonic Orchestra, the Telemann Chamber Orchestra, and the Essener Philharmoniker.
