Bob earned both his Bachelor’s Degree and MBA going to school at night while raising his family and working full-time. Bob was an early pioneer in the field of business information systems, and he founded and ran his own business, Dennen Computer Systems, for nearly 20 years, helping various Fortune 500 companies automate their business processes. He then served as Chief Information Officer for Phillips N.A. Later in his career, his knowledge of early computer systems helped many businesses navigate the Y2K transition.
Bob was a 57-year resident of Norwalk. He was a devoted parishioner and Eucharistic Minister at St. Philip Church, and served on their finance committee until his death. He was very active in the community, including various roles at Central Catholic High School and coaching numerous teams in the Cranbury League and with Pop Warner football.

Bob was devoted to Lorraine, his wife of 56 years, and missed her intensely after her passing. He was an encouraging and supportive father and grandfather. He attended hundreds of sporting events of his children and grandchildren. His most cherished memories later in life were attending his grandchildren’s sporting events and school performances. He took incredible pride in his children and grandchildren who are his legacy.
