Erin has a particular passion for working therapeutically with neurodivergent adolescents and adults, particularly those on the autism spectrum. Erin feels strongly about honouring neurodiversity in the pursuit of well-being and has lived experience of autism. She brings together her personal and professional understandings of autism in her therapeutic approach, while aiming to build a strong, collaborative therapeutic relationship based upon understanding and acceptance. Erin's manner is gentle and positive (albeit a tad quirky) and she draws from a number of treatment approaches including Schema Therapy, attachment-based therapies, Acceptance and Commitment Therapy (ACT), Cognitive Behavioural Therapy (CBT), Psycho-education, Positive Psychology, and skills building approaches.

Erin places the needs of the individual at the centre of her therapeutic approach so the experience of therapy is different for each and every individual. Erin enjoys altering her approach to suit the individual's unique cognitive profile and is in her element when working with individuals with cognitive profiles that vary from the norm, which may include giftedness, specific learning difficulties, and/or intellectual disability. Erin also offers “psychologically-informed mentoring” to assist neurodivergent individuals who have not developed any comorbid diagnoses to accept their lovely uniqueness, navigate the neurotypical aspects of the world, and develop a lifestyle that promotes wellbeing and mental health.

Prior to becoming a psychologist, Erin worked as a behavioural therapist with children with autism for a number of years which contributed to her understanding of, and fondness for, individuals on the autism spectrum. She has since expanded her field of interest and has gained experience in working with adolescents and adults experiencing a range of complex presenting issues. This led to an interest in Schema Therapy which saw Erin completing her Advanced Level certification in both Individual and Child-Adolescent Schema Therapy, and then co-founding the Centre for Schema Therapy Australia. In 2016, Erin gave a 90min presentation on implementing Schema Therapy with individuals on the autism spectrum at the International Schema Therapy conference in Vienna. Erin continues to publish and present about her approach to therapy with individuals on the autism spectrum and hopes to promote acceptance of autism through contributing to the development of therapeutic approaches that genuinely embrace neurodiversity and do not place neurotypical expectations on neurodiverse individuals.

Erin was awarded both First Class Honours in Psychology and a PhD in Clinical Psychology by Flinders University (Adelaide, South Australia). She has presented her work at international conferences and her research was published in the peer-reviewed journal “Autism”. Erin has been registered to practice as a psychologist since 2009 and gained endorsement in the area of Clinical Psychology in 2011.


Rachel is a Clinical Psychologist with an Advanced International Certification in Schema Therapy. She was awarded First Class Honours in psychology and a Masters in Clinical Psychology by the University of South Australia. Rachel was awarded the Australian Psychological Society Prize in 2011 and 2013, which recognises excellence in psychology and is awarded to students who gain first place at the end of their psychology degree. Rachel is registered with the Australian Health Practitioners Regulation Agency and is a registered Medicare provider.

Rachel has worked across government, community, and private settings and has experience working with varied and complex presentations including anxiety disorders, depression and mood disorders, childhood abuse and complex trauma, personality disorders, eating disorders, and relationship and parenting difficulties. She also has experience providing intensive family intervention for children with emotional and behavioural difficulties and autism spectrum disorders. Rachel is a registered Circle of Security Parent Facilitator.

Rachel utilises Schema Therapy, Cognitive Behavioural Therapy, Acceptance and Commitment Therapy, Attachment Theory, and Mindfulness to help people break free from the negative life patterns that underlie longstanding psychological difficulties and challenging relationships.

Rachel is a member of the International Society of Schema Therapy (ISST) and has undertaken training and supervision in Schema Therapy with supervisors in Australia, the Netherlands, and the United States. She has published research on group Schema Therapy and is part of an international research group which is currently investigating the effectiveness of individual Schema Therapy for Severe and Enduring Anorexia Nervosa. She has presented her research at the Australian Association for Cognitive and Behaviour Therapy conference and recent ISST conferences in Istanbul and Vienna where she presented in a symposium on brief group schema therapy chaired by Dr. Joan Farrell and Dr. Jeffrey Young, founder of Schema Therapy. She offers training and supervision in schema therapy through the Centre for Schema Therapy Australia (www.centreforschematherapy.com).
