Born and raised in Vietnam, Fr. Do came to the United States at the age of 16. Before finishing high school, he left home in upstate New York and traveled to California to join the Congregation of St. John the Baptist, a Chinese missionary order. After two years of postulancy, he was sent to Taiwan to learn Mandarin and enter the novitiate. When his visa expired less than a year later, he returned to the United States and ended up in New York City, where he studied at Queens College and worked at Our Lady of China Chapel. In 2001, he was sent to Mount Angel Seminary in Oregon to finish his undergraduate studies. In 2002, the Congregation sent him to Rome for theological studies, but he didn’t stay there long. In the fall of 2003, the Congregation sent him to Holy Apostles Seminary in Connecticut. He graduated from there in May 2005. That summer, he left the Congregation and joined the Diocese of Brooklyn in New York City. The Diocese sent him to the Seminary of the Immaculate Conception in Huntington. He was ordained a deacon there on December 8, 2006 and a priest at the Cathedral Basilica of St. James in Brooklyn on June 2, 2007. Now he is assigned to St. Rosalia-Regina Pacis parish in Brooklyn.
