After retiring from IBM in 1993, Bob worked for NYConn Data Systems which later became BWIR working as their IBM hardware solutions salesman. He retired from that company this past August. In addition to his wife, Bob leaves his two daughters and their families: Heather Cipolla and her husband, Jay, of Montpelier, VT and their two children, Catherine and Jonah; Susan Dorr and her husband, Robert, of San Antonio, TX and their two children, Sara and Lydia.
