In 1998, Dore sold his business. Soon after this he became aware of pioneering research into how skills are developed in the brain – driven by professors from Harvard Medical School and Sheffield University. He believed that this might give him the opportunity to help his severely dyslexic daughter Susie. She had become increasingly depressed and suicidal and by her early twenties had tried to take her own life three times. Following the sale of Nullfire, Dore was involved with a number of successful companies, including A-Zyme Ltd, Action! Telemarketing Ltd and Calktite Products Ltd, which were all later sold or merged.
