Dr Thea van der Merwe
Dr Van Der Merwe is the resident specialist psychiatrist for Changes Rehab in Johannesburg.
Dr Thea has worked in private practice since 2006 and has worked closely with other physicians and neurologists to find better ways to treat patients more comprehensively. She took a special interest in addiction back in 2003 while she was still studying. She learned that addiction was a much more complex mental health issue than it seemed and that the substance abuse was often only a symptom of many complex deeper problems.
It became my passion to look at a patient as a whole, using medication, supplements, therapy and some lifestyle changes. These all play a role. Full Remission is the goal in modern psychiatry. We should do as much as we can to achieve this.
Did you know Changes Rehab is accredited by all major healthcare associations and national health organisations and adheres to internal protocols that far exceed the codes of conduct or norms and standards for effective treatment of patients with addictions and other mental health issues.





Premium South African Medical Aid associations pay for patient treatment for the first 21 days in our private primary care facility in Johannesburg.
