About

Jieying (Allie) Xie is a psychotherapist, mental health social worker, and applied music neuroscience specialist, who specialises in neurodiversity, anxiety, depression, and trauma. Her focus spans across neurodevelopmental conditions such as autism and ADHD, trauma, and the complex ways they intertwine with lived experience, emotion, and nervous-system regulation.

As a mental health professional living with ADHD herself, Allie holds the rare advantage of experiencing her subject matter from both inside and outside the clinical lens. This dual perspective deeply informs her philosophy: to treat every person as one integrated system, through a biopsychosocial approach that unites body, mind, and environment.

Allie’s professional journey began with a Bachelor of Law in Social Work and a Master of Social Work, where she explored how individuals interact with their social environments. As she evolved into a mental health social worker and psychotherapist, her focus shifted toward the psychological dimensions of human experience. Yet, through years of private practice, she identified a recurring gap: while clients often understood their behaviour cognitively, translating that understanding into real-life change was inconsistent — sometimes effective, but often not.

Driven by this observation, Allie began a cross-disciplinary exploration to uncover what truly drives human behaviour — why something works on some days, but not others. Her research led her deep into physiology, human anatomy, and neuroscience, revealing the crucial “missing link” in the biopsychosocial equation. Traditionally, “mental health” has been seen as something abstract, residing in the “mind.” Yet as advances in brain imaging technology continue to illuminate how thoughts, emotions, and behaviour are embodied in neural systems, the once-invisible bridge between mind and brain becomes clearer.

As Allie often notes:

“If you think a mental health problem is ‘all in your head,’ you’re right — and so is your brain.”

Bringing these insights together, Allie developed the Multi-Level Nervous System Framework™, a holistic model that integrates neuroscience, psychology, and social work. Her approach works across biological, psychological, and social layers, using tools such as breathwork, movement, and music to restore balance and coherence throughout the entire system. The result is a therapeutic process that is scientific yet deeply human, grounded in research yet alive with creative embodiment.
