Professor at the Lyon Conservatory, member of the Alter Duo (France)

“Jeroen took care of my double bass beautifully. He knows how to listen to the musician’s expectations and does not hesitate to take the time it takes to make the ideal setting. It is always a great pleasure to come to his studio. We always leave having learned a little more about our instrument! ”
