In 2013, he was granted retirement and moved into a private residence. In 2016, he became a retired priest in residence at Holy Trinity Parish in St. Ann.

Father Pieper was known for his care in visiting those at nursing homes, hospitals and residences. He also regularly celebrated Mass at the Potosi Correctional Center. He was known for his acts of love and charity, hard work in manual labor, his many hats and constant smile and goodwill.

He is survived by a brother, Jerry Pieper of O'Fallon. Burial was in the cemetery at St. Joachim.
