Full Biography

Dr Catherine Llewellyn was a Choral Scholar at St Catharine’s College, University of Cambridge (UK). During her time at the University of Cambridge she completed a BA Hons (Part II Pharmacology) with first class honours, and was awarded the John Addenbrooke Medical Studies Prize 2000, The Moses Hollway Scholarship 2000, and the Astra Zeneca Prize for Pharmacology 2000. Dr Catherine Llewellyn was subsequently employed as a supervisor for Part IB Pharmacology undergraduates at the University of Cambridge.

Dr Catherine Llewellyn completed her medical degree at the University of Cambridge School of Medicine in 2003, achieving Distinctions in both Medical and Surgical final examinations. She was awarded the John Addenbrooke Medical Studies prize for the second time in 2003.

Dr Llewellyn migrated to Australia in 2004 and worked as a Registrar in Adult and Paediatric Emergency Medicine, General Medicine and Intensive Care for a number of years before deciding upon a career in Psychiatry.

Dr Llewellyn completed psychiatric training in Australia and was the first Psychiatry trainee in Australia and New Zealand to complete Advanced Training in both Child and Adolescent Psychiatry and Addiction Psychiatry.  Dr Catherine Llewellyn was awarded the RANZCP Addiction Psychiatry Prize in 2012.

In light of her broad range of experience, training and interests, Dr Llewellyn feels strongly about providing quality care to children with Developmental Disorders (including Aspergers, Autism Spectrum Disorders, and Attention Deficit Hyperactivity Disorder).  Unlike a Paediatrician, Dr Llewellyn has skills in both medical management and behavioural or psychological interventions.  Catherine is very happy to see your child or teenager for a comprehensive one off assessment and GP management plan (Medicare Item 291), or for the purposes of Education Queensland Verification, or to provide ongoing care.

In addition, Dr Llewellyn is passionate about supporting children, teenagers and adults struggling with eating disorders (including problem dieting, orthorexia, anorexia, binge eating, bulimia nervosa, and other types of disordered eating). Eating disorders can be associated with a range of serious medical complications which are often under-recognised and misunderstood.  Due to her strong medical background and being a Lifestyle Medicine Physician, Dr Llewellyn understands and is able to manage both the psychiatric as well as the medical aspects of eating disorder treatment.
