Gordon Piatanesi was part of the famous Piatanesi family accordion dynasty that started with the arrival of Colombo Piatanesi in San Francisco from Castelfidardo, Italy around the turn of the century, and his later establishment of Colombo & Sons Accordions on Columbus Ave. only a few blocks from our Caffe Trieste flagship location, more. Colombo is one of the most recognized of American-made brands, and the historic manufacturing, import and repair location operated under Gordon’s direction until the mid 1990’s on Columbus Avenue, after which it moved to San Rafael, CA. Gordon was a witty, highly skilled and trusted accordion artisan who took great care of my accordions for several decades. He was widely known and loved, and we will miss him very much.
