He served as the United States Ambassador to Nicaragua (1979–1981) and to Uruguay (1977–1979).^[4] He was also the executive director of Catholic Relief Services from 1983 to 1992.^[6]

Pezzullo was born in New York City, and attended high school in Levittown, New York, and Columbia College, from which he graduated in 1951 on a G.I. Bill as a history major.^[7][6]

After college, he taught high school in Levittown, New York for six years before joining the United States Foreign Service.^[1] He served in Ciudad Juárez from 1958 to 1960, Saigon from 1962 to 1965, La Paz from 1965 to 1967, Bogotá from 1967 to 1969, and Guatemala from 1969 to 1971.

He served for two years before being appointed as the United States Ambassador to Nicaragua by President Jimmy Carter in 1979.^[9] During his tenure as ambassador, Pezzullo negotiated the abdication of Anastasio Somoza DeBayle and paved way for Sandinista rule in the country.^[1] Miguel d'Escoto Brockmann, foreign minister of Nicaragua, once said that Pezzullo was "the best U.S. ambassador to Nicaragua in this century" for ''trying to help his government understand the irreversibility of the process here and seek a modus vivendi with" the Sandinistas.^[1]

Pezzullo also served as ambassador to Uruguay from 1977 to 1979.^[10]

In 1983, he was appointed as the first layman director of the international Catholic Relief Services and helped relocate the headquarters of the organization from New York City to Baltimore.^[6]
