Dr Sandor Heng is a skilled and experienced dual diagnosis clinician. He has a Doctorate in Clinical Psychology and has worked in both private and public health sectors in Australia and Singapore. Though he describes himself as a behaviourist by heart and was schooled in Cognitive-Behavioural Therapy, he generally adopts an eclectic approach in treating addictions and mental health. By focusing on a strengths-based approach, he blends evidence-based practice with practice-based evidence to achieve clinical outcomes. He has a special interest in co-occurring disorders (addictive disorders and mental health disorders), and his philosophy of therapy is to be the best version of oneself, which he practices in his own life.

She believes that the heart of therapy is the collaborative relationship between the patient and the therapist. Hence, she works deliberately to develop a safe and secure environment to ensure the right fit.

Working extensively with struggling adolescents, high-stress professionals, and distressed family units, Tom focuses on practical, long-term outcomes. He helps clients dismantle destructive cycles, develop resilient emotional regulation strategies, and rebuild fractured relationships.
