Dr. Middleton works closely with a number of counsellors and psychologists in the Fremantle area as well as “One Healthy Community” and Alma Street Clinic. He utilises the commonwealth ATAPS (Access To Allied Psychological Services) and Better Access programmes to help patients gain rebates for their counselling consultations.
