Garret Barnwell is a clinical psychologist offering psychotherapy for adults and teenagers in Parktown North, Johannesburg.

I provide psychotherapy and assessments in person or online. My therapeutic style affirms the inherent value of each individual.

I am guided by what you bring to the therapeutic process and value the importance of the therapeutic relationship. I ground my work in evidence and will work with your personal strengths to overcome the challenges confronting you. 

I have a warm approach, and therapy offers a space that is non-judgemental and confidential, where you may be yourself.

Some of the areas that I work on include (but are not limited to): 

  • Existential concerns whether related to life and death, grief, or broader angst about the world we are living in
  • Life transitions (e.g., school, at work, immigration, taking on new roles in the family)
  • Relationship distress whether at school, work or in your personal relationships
  • Occupational stress and burnout (e.g., healthcare workers)
  • Depression, loss and melancholia
  • Panic attacks, compulsions, or anxiety
  • Acute trauma, post-traumatic stress and other significant stress responses
  • Living with chronic health issues (e.g., diabetes, cancer, pain)
  • Support during recovery from psychosis, hearing voices, paranoia, mania or other states that may be challenging to process
  • Men’s issues (such as relationship conflict and masculinity)
  • Climate anxiety and eco-grief 

Psychological Assessment

In-depth psychological assessments can sometimes help complement treatment, gain clarity in complex situations or be part of personal development, for instance. I am accredited in several gold standard personality assessments, such as the Minnesota Multiphasic Personality Inventory 2 (MMPI-2), Millon Clinical Multiaxial Inventory – Fourth Edition (MCMI-IV), the Myers-Briggs Type Indicator (MBTI), 16 Personality Factor Version 5 (16PF5) and other personality assessments.  I do not provide scholastic assessments nor offer neuropsychological evaluations.
