With solemn hearts, we announce the passing of Brien Patrick O'Brien (Sioux City, Iowa), whose presence will be deeply missed, having departed on October 16, 2025 at the age of 64. Family and friends are welcome to leave their condolences on this memorial page and share them with the family.
He was predeceased by: his parents, Donald and Ruth; and his brother John. He is survived by: his wife Mary; his children, Daniel (Monica), Timothy, Kennedy and Irelinn; and his sisters, Terry (Matt) and Shiuvaun.
In lieu of flowers we are asking for a donation of hats and mittens for grade school children as every year around Christmas time Brien would buy hats and mittens for the children on his bus that did not have any.
