Rev. Greg Apparcel

Fr. Greg Apparcel is the Rector of St. Patrick's Church (Chiesa di San Patrizio a Villa Ludovisi) and Chaplain to the US Faithful Residing in Rome.  On August 1, 2017, St. Patrick's officially became "A Mission for the Care of Souls of the US faithful residing in Rome or visiting the city,"  and Fr. Greg became Rector of the Church and Chaplain to this mission.

Father Greg’s grandfather was born in Martina Franca, a 14th Century medieval village in the Puglia region of Italy. In fact, he considers all of Puglia his ancestral home, especially the Salento area on the southern Adriatic coast.  Born in Alhambra, California, just down the road from Hollywood, a love of the film industry became an early part of Father Greg’s identity. He received his degree in these fields from the University of California at Los Angeles (UCLA), and later earned a Master’s degree in Public Health Education (also at UCLA) before entering the Paulist seminary in 1978. Having earned an M.A. in Theology from The Catholic University of America in Washington, D.C., Father Greg was ordained a priest in May of 1983 and served first as Chaplain at Clemson University in South Carolina and then as Assistant Pastor at Old St. Mary’s Church in San Francisco.  During this time he earned a third Master’s degree in Pastoral Liturgy from Santa Clara University. In 1992, Father Greg joined Paulist Productions and the Humanitas Prize organization for four years, and then on to Rome.
