“...My 1830 Joseph Simon Fortepiano, which was very badly water damaged, was repolished by  Marco De Lellis. The work was simply outstanding: I cannot image it done better by anyone, and  recommend his work in the highest terms. – Malcolm Bilson”

“Marco, I just wanted to say thank you again for the absolutely magnificent restoration and refinishing of our antique and valuable Hardman piano. The sound is extraordinary and the refinishing is just beautiful! You are a true craftsman and a professional and you have guaranteed the value of this beautiful piece for generations to come. If I can ever be of any help or give a recommendation to a potential customer, please do not hesitate to call.
Thank you again.

“Marco De Lellis displayed a fine craftsmanship in rebuilding my piano and with the pride and passion of a real artist. As an artist, what a joy to play and hear the piano, that I had hoped for, achieved beyond my expectations.”
