He had served prior to this as the Bishop of Castellaneta and concurrent to his term in office as an apostolic administrator for another diocese.
Riezzo was well known for his holiness, with the priests in his diocese coming to love and admire him due to his careful attention to evangelization and catechesis.
He had served as a professor following his ordination in Assisi and Molfetta prior to being nominated to the episcopate.
Following his retirement in 1981 he moved to his hometown where he served as a pastor in his childhood San Nicola parish where he was known for remaining for extended periods in the confessional and out visiting the sick.His holiness had been noted as a bishop in both dioceses and steps were taken after his death in 1998 in order to launch the cause for his beatification.
These initial steps culminated in 2004 after the cause commenced and Riezzo was titled as a Servant of God.
