Glen Provost was born on August 9, 1949, to Cyrus and Sadie Marie Blanchet Provost in Lafayette, Louisiana. Deciding as a young man to become a priest, Provost entered Saint Joseph Seminary College in Covington, Louisiana. He received a Bachelor of Arts in English Literature from Saint Joseph in 1971.[2]
After Provost's ordination, the diocese assigned him as associate pastor at St. Mary Magdalene in Abbeville, Louisiana. He also entered the University of Louisiana-Lafayette (ULL) in Lafayette.[2] He went to London in 1980 to study Victorian language at the University of London. Provost graduated from ULL in 1981 with a Master of Arts in English Literature.[2]
After eight years at St. Mary, Provost was named pastor of St. Leo Parish in Roberts Cove, Louisiana. Provost was moved to the St. John Cathedral Parish in 1985, where he would remain as pastor for the next 13 years. In 1987, he was appointed as a judge on the diocesan tribunal and as a member of the Catholic School Board.[2]
Provost was appointed bishop of Lake Charles by Pope Benedict XVI on March 6, 2007. He was consecrated on April 23, 2007, with Archbishop Alfred C. Hughes as principal celebrant.[1] His installation brought to a close the two-year 'sede vacante' the diocese experienced after his predecessor, Bishop Edward Braxton, was appointed Bishop of Belleville, Illinois, on March 15, 2005.[1]
In addition to English, Provost speaks French, Italian, and Spanish.[2]
