Orchestras such as the Hague Philharmonic, the Netherlands Philharmonic and several of the provincial orchestras have joined and offer these master students the opportunity to prepare and work with them. He has also worked frequently with the Chetham School of Music, the Royal Northern College of Music in Manchester and, more recently, the Royal Academy of Music and the Royal College of Music, both in London, and Cambridge University.
