"Colin Campbell has been coming to Mexico to service harps for many years now and has worked on private instruments as well as for the prominent music institutions in the country. His attention to detail, quality work combined with his willingness to help out in any way possible in a country where we are desperately lacking in harp parts, strings etc. makes for total client satisfaction and I highly recommend him!"
-Janet Paulus, Principal Harpist with the Symphony Orchestra of the UNAM, the Orchestra of the Theater of Fine Arts and the Mineria Symphony Orchestra

-Faye Seeman, Principal Harp, Chicago Sinfonietta Orchestra, Professor of Harp Studies, Wheaton College and Northern Illinois University
