About Sydney DBT

Sydney DBT is part of a network of DBT Clinics providing Dialectical Behaviour Therapy (DBT) and Radically Open DBT (RO-DBT) programs that have been accredited by the Australian DBT Institute. Sydney DBT clinicians have attended Comprehensive Training in DBT and are Credentialed DBT Practitioners. We also have a number of clinicians who are intensively trained in Radically open DBT through Radically Open Ltd.

In 2015 we opened Sydney DBT in the CBD and in 2021 moved to our current location in Mona Vale NSW.

Sydney DBT is an accredited service of the Australian DBT Institute which develops mental health professionals throughout Australia, New Zealand and South East Asia in Dialectical Behaviour Therapy since 2004. The DBT Institute was established following a formal partnership and extensive mentoring through Marsha Linehan’s (developer of DBT) training organisation Behavioral Tech LLC between 2003 and 2008.
