Meet The Team

Dr Ruth Crowther is a Clinical Psychologist and founder of Quadrant Integrated Psychology and Quadrant Consulting in Brisbane. Ruth also holds an Adjunct Senior Lecturer role in the School of Psychology at the University of Queensland.
Ruth has over 25 years professional experience across academic teaching, research, clinical supervision, leadership roles, and more recently applied therapeutic work.

She holds a PhD and MPhil focused on the effectiveness of models of care for mental health recovery, with more recent work exploring rehabilitation settings, integration of digital mental health tools into therapy, and the clinical use of biometric data.
Ruth has worked closely with many clients experiencing trauma, addiction, burnout, anxiety and depression—especially in high-achieving individuals. In addition, she works with clients either with a diagnosis of ADHD or questioning neurodiversity as a possibility.

She draws on Schema Therapy, EMDR, Internal Family Systems (IFS), ACT, and DBT, and integrates somatic and polyvagal-informed approaches including biometrics / wearable data. Her work bridges clinical psychology, neuroscience, and health technology, with a focus on prevention, wellbeing, and systemic change.
Ruth also has a passion for the use of nature based and animal-assisted therapies, working alongside her (in-training) therapy dog Keeva to bring calm and connection to the therapeutic space.
