Roman was born on April 23, 1927, in Detroit, Michigan, son of Roman and Mary Theresa Theisen. He had two brothers, Charles and Leon. He attended St. Alphonsus Parochial School in Dearborn, Michigan, and studied for three years at the University of Detroit High School before entering Maryknoll Apostolic College (Venard), Clarks Summit, Pennsylvania on September 2, 1944. On October 10, 1944 he wrote of his vocation to Maryknoll, “I remember that on my application to Maryknoll I wrote that I first became interested eight years ago because I definitely know that I was in the second grade and I and my brothers were filling dime cards sent out by Maryknoll. However, I think the influence having the most effect on me has been the Field Afar, coupled with the encouragement of my parents.” At Maryknoll Seminary in Ossining, New York, he obtained his Bachelor of Arts degree in Philosophy in June 1950, and his Master of Religious Education in June 1954. He was ordained a priest with his classmates in Annunciation Chapel at the Maryknoll Sisters Motherhouse, Ossining, on June 12, 1954.

Father Theisen loved Maryknoll and his vocation as a missionary Priest. In 1998 he wrote a book titled “People I Love.” In the opening of the book he writes “The good Lord has blessed me with his love and with the love of many good friends both in my homeland and in the Field Afar. I thank God for his gift of love and you, my friends for yours. I love you.” Father Theisen’s book shares stories of many people that have touched his life as a Maryknoller and missionary Priest.
