Dennis “Denny” Keith O’Riley

Dennis Keith O’Riley, affectionately known as Denny, died on October 18, 2026, in Bargersville, Indiana. He was born on October 31, 1955, in Bell, Texas.

Denny built his working life as a self-employed IT specialist, bringing dedication and independence to his profession. He also served his country with pride as an Army veteran of the 82nd Airborne Division, a distinction that remained an important part of his life.

He will be remembered as a man of many interests and strong enthusiasm for the things he loved. Denny was a member of the Indianapolis Darts Association and found joy in music, playing guitar with the Memories Band. He was also an avid fan of Indianapolis sports and traditions, especially the Indianapolis 500, the Indiana Fever, the Indianapolis Colts, and the Indiana Pacers. These passions reflected the energy and spirit he carried into everyday life.

Denny is survived by his sister, Diane (Shawn) Gudat; his brother, James O’Riley; and his uncle, Rev. Dennis H. O’Riley, several nieces and nephews.  He was preceded in death by his parents, Daniel F. and  Mary Denise (Egry) O’Riley. May their memories bring comfort to those who knew and loved him.
