He was born Georges Francis Garmo in 1921 in Tel Keppe near Mosul, Iraq to a Chaldean Catholic Assyrian family.

Garmo returned to Iraq in the summer of 1947, where he would spearhead the new and improved Philosophy and Theological studies at Chaldean Patriarchal Seminary the following year.

Patriarch Mar Paul II Cheikho appointed Garmo as pastor of Mother of God Chaldean Catholic Church in Southfield, Michigan, a suburb of Detroit.

[1] In 1964, while serving as pastor of Mother of God Church, Garmo began fundraising drives, with the help of the Parishioners and Parish council he was able to purchase a 9-acre (36,000 m2) plot of land in Southfield on Telegraph Road.

In July 1972, the community celebrated the groundbreaking of a newly built Mother of God Parish, as well as a social hall that was dedicated by Patriarch March Paul II Cheikho on 15 May 1973.
