Joseph was a proud graduate of Bishop John Neumann High School, Class of 1959. He went on to serve his country honorably as a Lance Corporal in the United States Marine Corps.

A man deeply committed to his community, Joseph was a member of the Elks Lodge #1224, where he served as Exalted Ruler from 1991 to 1992. He was also a devoted member of American Legion Post 273 in Madeira Beach, Florida, and a faithful parishioner of St. Jude the Apostle Cathedral for over 43 years.

Joseph was a devoted husband, father, grandfather, and brother. He is survived by his loving wife, Doris O’Brien (née Gilchrist); his children, Joseph O’Brien, Maureen (Terry) Trout, and Daniel (Inja) O’Brien; his beloved sister, Margaret McGlynn of Wilmington, Delaware, with whom he shared a daily bond; and his cherished granddaughters, Megan (Garrett) Shivel and Kacy Trout.

He was preceded in death by his mother, Mary O’Brien.

A committal service with military honors will be held on April 20, 2026, at Bay Pines National Cemetery, where he will be laid to rest.

In lieu of flowers, the family kindly requests that donations be made in Joseph’s memory to the Wounded Warrior Project.
