Born in New York City in 1929, Krushenick dropped out of high school, served in World War II, worked on constructing the Major Deegan Expressway, and then returned to art school, with the help of the GI Bill. He attended the Art Students League of New York (1948–1950) and the Hans Hofmann School of Fine Art (1950–1951). In 1957, he and his brother, John Krushenick, opened a framing shop on Tenth Street, which quickly turned into an artists’ cooperative called Brata Gallery. Artists such as Al Held, Ronald Bladen, Ed Clark, Yayoi Kusama, and George Sugarman exhibited there. In 1962, Krushenick left the gallery and began receiving solo-exhibitions around the world. In the 1960s and 1970s, he was a prominent painter in the New York art scene. However, in his later years, Krushenick taught at the University of Maryland, College Park from 1977 to 1991. He died in New York on February 5, 1999, at age 69.
