He designed Digital's Gold Key Word Processing user interface in 1975, became Product Group Manager for Word Processing Systems and later as Technical Manager for the Engineering Group which produced Digital’s Electronic Mail and All-in-One Office Automation System. His last assignment was Director of Comparative Analysis before his retirement in 1992 to return to the consulting field.

He volunteered as a Catholic Eucharistic Minister with the Rehabilitation Hospital of the Cape and Islands in Sandwich, MA.
