Our clinic was founded by Dr Gayle Maloney, a Senior Clinical Psychologist and Associate Clinical Professor at Yale OCD Research Clinic. Dr Maloney has provided treatment to OCD sufferers and their families in Perth for over 20 years. She was awarded a prestigious Fulbright award fellowship to establish an ongoing international research collaboration between the Perth OCD Clinic and Yale University School of Medicine.

After working at the Yale OCD Research Clinic, she returned to Perth in 2015 and opened a dedicated OCD Clinic to provide a vital service to the Western Australian community. In doing so, she brought together a network of independently practising clinical psychologists who share a commitment to providing exceptional psychological care to OCD sufferers using evidence-based practice.

She earned her doctorate by focusing on research that investigated the causal factors leading to the development of clinical perfectionism and how it relates to the development of psychological disorders, including OCD.

Gayle has attended advanced OCD specialist training at the Behaviour Therapy Training Institute (BTTI) in the United States, provided by the International OCD Foundation. As such, she is passionate about providing supervision, professional development training and workshops on OCD to other mental health clinicians.
