Despite longstanding efforts to implement multidisciplinary approaches within mental health care systems, contemporary therapeutic practice remains largely fragmented across the fields of psychology, psychiatry, psychotherapy and neuroscience. These divisions reflect entrenched historical and professional boundaries which limit our ability to adequately address the holistic complexity of human experience. This opinion piece argues that such fragmentation is both theoretically outdated and clinically restrictive. Drawing on our work in embodied trauma, we propose that the now widely rejected concept of mind–body dualism necessitates a genuinely holistic and integrative framework for mental health care and psychotraumatology practice. This includes a holistic approach that spans the bio‐psycho‐social‐sexual‐spiritual‐existential‐cultural realms of human experience. We conceptualise this within a constellation of care model, emphasising the urgent need for relational, culturally responsive, trauma‐informed and holistic therapeutic engagement. Bridging disciplinary divides, we suggest, is not simply advantageous, but essential for achieving meaningful and sustained therapeutic outcomes.
