About Us

Our psychologists offer a diverse range of therapies, and our staff include endorsed clinical and counselling psychologists.

Successful psychology treatment is about establishing a trusting relationship with the psychologist. Both clinical and counselling psychologists are trained extensively in assessment, diagnosis, and evidence-based treatment of high prevalence mental health disorders such as anxiety, depression, and substance use disorders.

  • Clinical psychology training tends to cover more low prevalence mental illnesses such as bipolar disorder, schizophrenia and psychotic illnesses, and developmental disorders such as Autism spectrum disorders. Both clinical and counselling psychologists are skilled in the treatment of mild, moderate, and severe mental illnesses including those of a chronic and complex nature.
  • Counselling psychology training tends to focus more on psychotherapy theory and practice including various evidence-based models of intervention, and counselling psychologists are also trained in a variety of modalities including couple, group, mother-infant, and family therapy.

In practice, it is estimated that there is between 70 – 80% overlap between the two endorsements. In real life, the “match” between therapist/psychologist and the client is the most important determinant of a successful treatment process.

Please discuss your needs and concerns with our office manager Amy, who will establish which practitioner is right for you.
