Fr. William Nicholas was born in Southern California.

He spent a great deal of time visiting the San Francisco Bay Area where some of his family lives.

He was ordained to the Priesthood by Archbishop William J. Levada for the Archdiocese of San Francisco, CA in June, 2001 after completing studies at St. Patrick’s Seminary in Menlo Park, CA. with an M.A. in Theology, a Masters in Divinity (M.Div.) and a Bachelor’s in Sacred Theology (S.T.B.).  He also completed a Masters in Business Administration (MBA) with a concentration in Marketing in 2012.

He has served as parochial vicar in all three counties of the Archdiocese of San Francisco, beginning in the southern-most parish, and, for his third assignment, in the northernmost.  In 2011 he was assigned to serve in the oldest church in San Francisco, Mission Dolores, founded in 1776, attached to which is Mission Dolores Basilica, the first Basilica west of the Mississippi River, declared in 1952 by Pope Pius XII.  In the Summer of 2013, he was granted an opportunity to serve for five years in the Archdiocese of Los Angeles, where he was born and raised.

He returned to the Archdiocese of San Francisco in 2018, and in the summer of 2019 was assigned to the Cathedral of St. Mary of the Assumption as parochial vicar.

He has also participated in programs for continuing education of Catholic School teachers and has been invited to be a guest speaker at high school functions.  He has conducted Parish Recollections and Missions within his own Archdiocese, in Southern California, and as far away as Chalan Kanoa, Saipan.

Fr. Nicholas was invited to be a speaker at the 2011 and 2012 Los Angeles Religious Education Congress in Anaheim, California, where he spoke on the Old Testament Prophets, the Psalms and Biblical Apocalyptic Literature.  He also has been a regular speaker at the annual University Series, a series of seminars conducted annually during Lent in parishes throughout the county of Ventura, California, as well as in the Whittier area and in Marin County, California.  

Fr. Nicholas enjoys Reading (especially the classics and historical biographies), Movies (especially the older classics – Casablanca is his favorite), Fishing (especially when they actually bite) and Traveling (especially road trips throughout the United States).  

He continues to be available for Parish Missions, Adult Faith Formation Seminars, Recollections and Presentations.
