Tim is a Clinical Naturopath with a Bachelor of Naturopathy from Southern Cross University, NSW and a Bachelor of Science.

His expertise in digestive disorders and conditions related to gut barrier function such as allergies and autoimmune disease has developed over more than 10 years of practice.

Tim’s particular interest is the gut microbiome- a complex ecosystem that feeds off what we can’t digest, producing vitamins, important metabolites and aiding in mineral absorption. Our gut microbiota protects us against invasive disease-causing microorganisms and plays a vital role in regulating our immune system. This ecosystem can be modulated using nutrition, herbal medicine, probiotics and prebiotics. Significant, measurable improvements in gut barrier function are achievable, which can be expected to improve symptoms and reduce disease activity. You can learn more at Advanced Microbiome Restoration.

Naturopathic treatment can be highly complementary to orthodox care or, in the case of functional digestive disorders such as IBS, can be an effective primary treatment. Tim stays in close communication with treating GPs, Specialists and other health providers to ensure safe and effective care.

Tim practices in Perth on a fortnightly basis. He lives in Margaret River with his partner and two teenage children, where he likes to surf, ride his bike and make things in the shed!
