Vass is based in Sydney and works with individuals through short-term counselling and longer-term psychotherapy. He holds degrees in psychology, counselling and psychotherapy, and has been trained in psychedelic-assisted psychotherapy. He provides support for issues such as life dissatisfaction, negative thinking, anxiety, substance use and relationship difficulties.

Vass mainly uses the psychodynamic modality, with the aim of increasing self-awareness and better understanding the effect of the past on present behaviour. He helps individuals examine how thoughts, feelings, and actions are interrelated, and how they systemically form habits that drive our behaviour.

Vass offers psychedelic harm reduction and integration for people who use psychedelics. This can help individuals plan, prepare and gain insight and meaning from their psychedelic experiences.
