He went to North Carolina in the summer of 1946 to study at Black Mountain College, where he was associated with faculty members Ilya Bolotowsky, who taught painting, and Charlotte Schlesinger, the piano instructor.
Their life at Black Mountain College was dramatically marked by a fire in 1953, which destroyed most of the Fiores' worldly goods and a large amount of finished work.
[4] His first significant show there was a two-man exhibition with fellow Black Mountain College alumnus and sculptor John Chamberlain at Davida Gallery in 1958.
He was a prominent artist among others such as Louise Nevelson, William Zurich and others who were important in the early years of the Maine Art Gallery in Wiscasset.
[1] James Thompson described Fiore's long artistic career as dividing into three periods: "The first, which began with his work at Black Mountain College, includes an exploration of modernism under Bolotowsky that started with a study of European masters like Picasso, Braque, and Klee and continued with America's first major school, the Abstract Expressionists.
[...] During the second major period of his art Fiore applied his knowledge of non-figurative composition to natural motifs: he became a landscape painter in a much more obvious and traditional sense.
