Denis C. Riordan

September 9, 2025

John Treanor worked with my father Jeremiah (Jerry) Riordan for many years at the Michigan Consolidated Gas Company. John gave a eulogy during my father's funeral Mass, and what John shared with those of us in the church that morning reflected his deep Catholic faith. And as detailed so well in the obituary above, John´s love and selfless support for others throughout his life is further testimony regarding the profound impact his faith had on him. John was a kind man. He was a good man. And I will always be grateful to him for honoring my father in such a thoughtful and generous way. May God grant John eternal rest.

Sincere condolences to John's wife and family.
