Tarisio's New York offices and gallery are at 244–250 W 54th Street, in the former workshop of the prominent French violin dealer and restorer Jacques Français. Français was joined in 1964 by the luthier René A. Morel, also a Frenchman, who later opened his own shop in the same space. Morel continued to work in collaboration with Tarisio until the summer of 2011, offering soundpost adjustments and other expert services. After Morel's retirement, he was succeeded at Tarisio by his colleague the luthier Stefan Valcuha, who restores lutes as well as taking care of their general maintenance.
