Woj Pryba

Psychologist

Dr Woj Pryba is a member of the Australian Psychological Society (APS) with endorsement as a Board Approved Supervisor in the area of clinical supervision to intern and registered psychologists. His tertiary qualifications are supported by a Bachelor of Arts in Psychology, followed by a Master of Arts degree in Psychology and following the end of Apartheid in South Africa, he proudly completed his Doctorate researching the Upward Career Mobility of Black Business Managers. Spending time at different Business Graduate Schools, he completed a Management Development Program, regarded as a mini-MBA and holds a Certificate in Training as well as a Graduate Certificate in Human Resources. Woj’s work as a psychologist supports clients struggling to resolve trauma, workplace bullying, depression, anxiety, relationship difficulties, grieving the loss of a loved one and a range of other mental health disorders. Considering mental health interventions, Woj aims to create an unfair advantage for his clients. He unapologetically focuses on unleashing all his knowledge and experience gained over the past 35 years in Psychological Wellbeing, Crisis Intervention, Risk Assessment and Relationship Counselling to gain a growth advantage for his clients. Feeling both privileged and humbled at the same time, Woj supported survivors of the Lismore floods and survivors providing testimony in the Royal Commission into Institutional Responses to Child Sexual Abuse and the Royal Commission into Defence and Veteran Suicide. As an unshakable optimist, when asked what key trait underpins Woj’s success, he says he is willing to be in the corner of those who feel that no one cares about them. He uses basic clinical skills to provide compassionate psychological counselling to those needing to overcome personal hurdles, both in and outside of their workplaces. He will encourage you to recognise unhelpful behaviours limiting your ability to keep you connected to healthy wellbeing patterns. He will also urge you to see how this disconnect leads to further vulnerability in other parts of your life. Rather than leave this vulnerability unaddressed, Woj encourages us to start the process to end the mental suffering and make things better. The first step starts with a conversation.
