Dr Fong held various appointments in his career in the SAF, including the head of the RSAF Aeromedical Centre, the Senior Medical Officer (Health Care) of HQ Singapore Armed Forces Medical Corps and the Commander of the Singapore Armed Forces Military Medical Institute. He was also involved in the development of many new areas for the SAF, including the Aviation Physiology and the High G Training programme for the RSAF, the development of the new Aeromedical Centre Building, the commercialisation of selected medical services of the RSAF Aeromedical Centre, the establishment of the Human Science Research Office for the SAF and the development and consolidation of the Military Medical Institute for the Singapore Armed Forces.

After retirement from military service in 2007, Dr Fong joined ST Medical Services as the Medical Director (Education) in charge of Aviation Physiology Training for the Singapore Aeromedical Centre until 2023. Dr. Fong's interest lies mainly in the development and training of aircrew, to be aware and to be able to cope with and manage the in-flight physiological demands of high-performance flight, maximising flight safety and performance.
