Phimphisan was born in Bangkok. He professed religious vows as a Redemptorist and studied for the priesthood at Immaculate Conception Seminary in Oconomowoc, Wisconsin, USA. He was ordained a priest on June 24, 1958.
Father Phimphisan served as a priest in the Vice Province of Bangkok until October 2, 1975, when Pope Paul VI named him to be the second bishop of the Diocese of Udon Thani. He was ordained a bishop by his predecessor, Bishop Clarence James Duhart, C.Ss.R., at the Cathedral of Our Mother of Perpetual Help on December 12, 1975. The principal co-consecrators were Archbishop Michel Kien Samophithak of Thare and Nonseng and Giovanni Morettiet the Apostolic Pro-Nuncio to Thailand, and the Apostolic Delegate to Laos, Malaysia and Singapore.[1]
Bishop Phimphisan served as the Apostolic Administrator of the Archdiocese of Thare and Nonseng from May 14, 2004, to July 1, 2005.[2] He was the president of the Bishops’ Conference of Thailand for three terms: 1991–1994, 1997–2000 and 2006–2009.[3] He served the Diocese of Udon Thani for 34 years as its bishop before his resignation was accepted by Pope Benedict XVI on November 14, 2009.
The Bishop died on December 15, 2017, around 14:10 at Aek Udon Hospital.[4]
