An American citizen, Osvaldo Mariscotti grew up in Piedmont, Italy. While he demonstrated artistic talent at a very young age, frequent family relocations during his childhood prevented him from fully developing his skills. These travels, however, first throughout Europe, then South America, and finally the United States, provided him with a deeply international background that influenced his later artistic development. After obtaining a degree in Engineering and developing several important real estate projects, Mariscotti finally turned to art fully. He participated in several national exhibitions and had his art photographed and exhibited widely. He presented his first solo show at Artopia Gallery in New York and soon after started a four-year exclusive contract with Artsforum Gallery, also in New York. He has since exhibited his art throughout the world, both in international exhibits and festivals as well as prestigious international art publications, although he continues to live and work in New York City.

Osvaldo Mariscotti is currently represented by Upsilon Gallery based in New York City.
