Gordon was a founding member of the British Paediatric Neurology Association in 1975 From 1958, Gordon attended meetings of the UK Paediatric Neurology group in St Edmund Hall, Oxford and the group slowly formed the idea of establishing the first association of that type in the UK. Gordon work was fundamental in establishing the Association, and for his efforts was elected to be the first President of the Association, a position he held for 6 years. Through work to establish the association, other European countries took notice and established similar associations. These were brought together, starting in 1971, in a federal structure by 1980, to become the European Federation of European societies of paediatric neurology in 1980, that would later become the European Paediatric Neurology Society. Gordon became president of the organisation in 1980 for a two-year term. Gordon was also on the board of the International Child Neurology Association. Gordon was interested in rare diseases, and this was reflected in his publications, and eventually became a consultant in rare diseases both within the UK and abroad. His most important field however, was paediatric neurology, a field in which he excelled. What concerned him most was the topics of chronic disability, cerebral palsy, epilepsy, Language disorder, learning disability, Accident-proneness, emotional and behavioral disorders, all medical disorder's that are within the field of paediatric neurology. Gordon in conducting research and writing publications examined in detail, those who had suffered from learning disabilities and low self-esteem could later lead to clumsiness and failure at school. Out of this research he published a book in 1976 called "Neurological problems in childhood" and later republished by Butterworth-Heinemann 1993. Gordon was the awarded the prestigious James Spence Medal in 1985.
