Dr. Mark Ryan
MBBS, RANZCP, BCN -Head Psychiatrist
Mark Ryan is a psychiatrist with an extensive background in consultation-liaison psychiatry, precision medicine and neuromodulation. He has served as Clinical Lecturer at both Sydney University and the University of NSW, and worked at major hospitals across NSW. His approach goes beyond diagnostic labels and symptom-based treatments in psychiatry. Diagnostic labels are summary descriptive socio-cultural, ‘fuzzy’ constructs that often fail to capture the complexity of an individual's state with significant symptom overlap across categories and with typically low inter-rater reliability. The patient is not the diagnosis, which is after all an abstract ‘human kind', and not a ’thing’. Instead, he orientates to a systems-based, allostatic perspective—one that recognises symptoms as signals of an organism’s allostatic response to chronic stress rather than as a manifestation of a ‘spanner in the works” to be eliminated.
Dr. Ryan’s approach incorporates comprehensive, individualised assessments that transcend categorical diagnoses to consider underlying interacting physiological, metabolic, psychological, behavioural and sociocultural and political and other contextual factors. These contextual factors are significant determinants of health/illhealth. This assessment enables greater precision, consideration of factors additional to symptoms and a more informed and comprehensive and personalised assessment and understanding incorporating more than the treatment guidelines that are derived from group averages and which necessarily require translation to each individual patient.
His work aligns with contemporary shifts in psychiatric thought, incorporating systems medicine, neuroscience, chronic stress physiology, allostatic adjustments and modification of the predictive model to restore flexibility and adaptive capacity in patients. His approach ultimately aims to facilitate self-regulation and healing, rather than only attenuating/alleviating symptoms.

Dr. Joanne Shannon
BVSCHons MB BS RANZCP - Psychiatrist
Dr. Shannon is a Psychiatrist who incorporates a range of evidence-based therapies, helping her patients discover their own unique pathway to recovery from mental health problems. Joanne has more than 15 years’ experience as a Psychiatrist and treats patients of all ages presenting with Bipolar Disorder, Depression, Anxiety, Schizophrenia and Trauma and other related mental health issues.
Dr. Shannon previously practised as a veterinary surgeon, and in this time realised many of the animals’ owners were presenting with mental health issues that did not seem to be addressed. Joanne was then motivated to train in Psychiatry, gaining her qualifications at the University of Sydney. She has since practiced at St George Hospital in Kogarah, St Vincent’s Hospital in Darlinghurst, the Richmond Clinic in Lismore, Neurocare Clinic Sydney and also works with the Justice Health & Forensic Mental Health Network.
Joanne believes it is imperative that all patients have a choice in how their mental state is looked after and offers a broad range of evidence-based therapies. These include somatic therapies which focus on the body, Transcranial Magnetic Stimulation (TMS) as a short-term program for psychiatric disorders, and is currently leading research into the safety and efficacy of psychedelic assisted therapy.
Dr Shannon believes no single approach can sufficiently attend do all aspects of mental wellbeing and is thus committed to offering holistic solutions that address her patients’ unique circumstances.
Outside of the clinic, Dr. Shannon is trained as a Trauma Sensitive Yoga Facilitator.
