Become your best self.

Sometimes patterns of behaviour that aren’t serving us well can become entrenched and difficult to shift. It might be related to trauma in childhood, sexual abuse, and abusive relationship, or an eating disorder. Whatever the underlying cause, we can help you.

OClinic also offers additional, one on one support from highly experienced psychologists and behavioural therapists that we have carefully selected as being the absolute best at what they do. The sessions are tailored to your specific needs and circumstances, and are priced separately, with payment to the health professional directly. Medicare Mental Health Care plans may also be used to offset the cost involved. Contact us for more information.

Warren Artz

Warren is a specialist weight management psychologist who has helped more than 4,500 people over the last 14 years with psychoeducation, guidance, and support after weight loss surgery. Unlike traditional psychologists, he works almost exclusively with those struggling with their weight. He believes strongly in setting realistic and achievable weight loss goals; and, he focuses on helping patients take rational behavioural control of their eating and lifestyle habits, whilst adhering to the demands of their weight loss procedure.

Warren is an ex-professional goalkeeper who has travelled the world as a soccer player and coach. He played in South Africa, England, USA, New Zealand, and Australia before becoming an AHPRA registered psychologist in 2008. He has undergraduate and graduate degrees in psychology from both the USA and Australia and has several published articles on the psychology of obesity and weight loss surgery.

Warren is a registered Medicare provider who accepts mental health care plans to support patients on their weight loss journey. He advocates building personal resilience as the key to achieving any goal. Personal challenges and experience have paved the way for a treatment approach that focuses on strengths, rather than weaknesses, and processes, rather than outcomes.
