He served as the Bishop of Tursi-Lagonegro, as the Bishop of Avellino, and as the Archbishop of Salerno-Campagna-Acerno^[1]. In this last role, he simultaneously held the title of Primate of the Kingdom of Naples.^{[citation needed]}.

After studying at the Archdiocesan Seminary of Salerno and the Pontifical Regional Seminary in Salerno, Pierro was ordained a priest by Demetrio Moscato, Archbishop of Salerno, on 21 December 1957.

On 14 August 1960, he was appointed a parish priest of the Church of San Nicola di Bari in Coperchia di Pellezzano, where he remained until 6 September 1981 when he became Bishop of Tursi-Lagonegro. On 18 November 1974, Pierro received a degree in theology from Pontificia Facoltà Teologica "S. Luigi" (the Pontifical Theological Faculty "San Luigi") in the Posillipo quarter of Naples. He then taught religion at the "G. Da Procida" high school in Salerno and dogmatic theology at the Pontifical Seminary of Salerno's Institute of Religious Sciences.
