Priest Deacon Staff (Revised on September 1st 2017)


Father Bao Thai – Pastor

Telephone: 714-544-3250, Ext. 14


Father Bao Thai was born into a non-baptized family in July 1970 in Saigon, South of Vietnam. Through an incredible series of events, he and his entire family converted to Catholicism nine years later on the feast day of the Solemnity of Our Lady’s Assumption, 8/15/1979.

After earning a B.Sc. in Computer Science from Saigon University (May 1992) and teaching at a high school for an academic year, he left Vietnam for Orange County in July 1993. In August 1995, he answered God’s calling and a yearning desire. He broke new ground when he entered Mount Angel Seminary in Oregon, where he obtained a B.A. in Philosophy (May 1998), and he continued on to obtain his M.Div. and M.A. in Spiritual Theology (St. John’s Seminary in Camarillo, May 2003), as well as his Licentiate of Sacred Theology (S.T.L.) in Spirituality (The Pontifical University of St. Thomas Aquinas – the Angelicum in Rome, June 2009).

Grounded in his faith, learning, and hard work, Father Bao has enthusiastically served God’s people. After his ordination to the priesthood of Jesus Christ at St. Columban on June 7, 2003, he has served at San Francisco Solano, St. Anthony Claret, Holy Family Cathedral and Our Lady of La Vang. He has come to St. Cecilia since July 1, 2015.

Father Nicolaus Thai – Parochial Vicar

Telephone: 714-544-3250, Ext. 31


Greeting Words from Fr. Nicolaus: 

In my continued gratitude to God for the gift of Priesthood, I joyful introduce myself to you as your new Parochial Vicar, starting July 1st, 2017! I also would like to express my thankfulness to Bishop Vann for his appointment and to Fr. Bao Thai, our pastor, for his generosity in accepting me, a new priest, and for his trust in having me as his new Parochial Vicar.

My name is Fr. Nicolaus Thai, a priest of our Diocese of Orange. I was born in 1984 in Saigon. I was baptized on March 11th, 1984 at Bac Ha Catholic Church, my home parish in the archdiocese of Saigon. It was at this spiritual home where I received the sacraments of Baptism, First Holy Communion, and Confirmation. In addition, I was also very involved in Eucharistic Youth Movement and, especially, was an altar server for quite a long time. In the hindsight, it was during these years in serving at the altar during Holy Mass that God planted in me the seed of the vocation to the Catholic priesthood.

My family and I immigrated to the United States of America in 2001 and settled in Fountain Valley. I then attended Los Amigos High School, Orange Coast College, Cal Poly Pomona, and Cal State Long Beach. With many prayers and the support from family and friends, I applied to our Diocese of Orange. I entered St. Patrick’s Seminary and University in Menlo Park in August 2009 as a seminarian of our diocese and was enrolled in the Pre-Theology Program. Having finished this program in 2011, our Bishop Emeritus, Bishop Tod Brown, sent me to the Pontifical North American College in Rome for my theological formation. I attended lectures at the Pontifical Gregorian University, where I earned a Bachelor’s degree in Sacred Theology (S.T.B.) in 2014. Having completed my Pastoral Year at Santa Clara de Asis, Bishop Kevin Vann ordained me to the order of Transitional Deacon on June 27th, 2015. I then returned to Rome to begin my graduate theological studies. After graduating from the Pontifical North American College (’16), Bishop Vann ordained me to the order of Priesthood on June 11th, 2016 during the Jubilee year of Mercy. After my ordination to the Priesthood I returned to Rome again for one more academic year to complete my graduate studies in theology and earned a Licentiate (equivalent to a Master’s degree) in Sacred Theology (S.T.L.) in June 22th, 2017.

Since St. Cecilia’s parish is my first pastoral assignment as a priest, there will be a lot of learning and trainings. Therefore, please remember me in your prayers and please be assured that you are in mine.

Sr. Francesca Tran, LHC – Confirmation Coordinator &
Vietnamese Children Faith Formation Coordinator (Viet CFF)

Telephone: 714-544-3250, Ext. 11


I am a member of the Lovers of the Holy Cross Sisters of Los Angeles since 1986 and this past summer 2014 marked my 25th Anniversary as a Vowed Religious in my Community. Thank God for choosing me – unworthy sinner to be His “vesselof grace” and my response is to have Him for life…J! I am the second child of nine siblings and the oldest girl in my family. We came to the USA in December 1975 with the first group of Vietnamese refugees called the “Boat People”. Thank God for our life here in America: the land full of milk and honey and freedom. I like to pray, eat, read, sleep and travel to holy places. I want to teach our young people about Jesus – God and their purpose in life and hoping one day they will come to know, to love and to serve Him. Faith formation for children and youth is one of my Community’s Charisms and we are sent out on this mission. I am looking forward to spread God’s Kingdom among our children and journeying with everyone here at St. Cecilia – my new “nest”of God’s Vineyard…J! May our Lord Jesus, Mother Mary, St. Joseph and St. Cecilia bless us and make us grow more deeply in love of God and one another.
