Dr Norman Hohl Practice Principal Health HQ

Dr Norman Hohl - MBBS (UQ), DipTropMed&Hyg, FRACGP FAFPHM

Make an online booking with Dr Hohl now
After graduation from the University of Qld in 1970 Dr Hohl worked in Papua New Guinea for 2 years and was confronted with the high death rate from preventable diseases such as Rotavirus Diarrhoea, Pertussis and Pneumococcal Pneumonia.
This experience persuaded him to focus his career on public health and preventive medicine.

After further training in Tropical Medicine Dr Hohl launched a rural health program in northern Nigeria focused on training already highly respected community leaders as village health workers supported by medical assistants and midwives. This reduced infant mortality 50% within 2yrs in each community involved in the program.
Fundamentally it was a program empowering communities to solve their own problems and thus it has been self sustaining. For this work Dr Hohl was awarded a Fellowship in Public Health Medicine see FAFPHM.

Back in Australian general practice Dr Hohl's focus continued on preventive medicine, and it became clear to him that a clinic focused on protecting travellers was needed so he opened the first Travel Medicine clinic on the Gold Coast in 1995.

In 2004 Dr Hohl was appointed a senior lecturer at the new Griffith University Medical School and 2 years later an Associate Professor at Bond University Medical School.
Scores of students and GP registrars have spent time in Health HQ as part of their training.

Health HQ's skilled and qualified practice nurses also teach student nurses from Griffith University at Health HQ.

For 7 years Dr Hohl also maintained a registered branch office in Western China run by skilled nurses focused on detection, treatment and prevention of Hydatid disease in the Yak herdsman and their families. Great progress has been made so the office was closed in 2011.

As a doctor who has had to treat cases of every single disease against which we routinely vaccinate children in Australia today, Dr Hohl values the role of immunisation very highly.
