Karden Rabin is the co-founder of Somia, co-author of The Secret Language of the Body, and a Neuroplastic Medicine Practitioner specializing in chronic pain and complex stress-related illness. His work centers on the role of the brain’s protective and alarm systems in driving persistent symptoms, and on retraining maladaptive neural circuitry to restore regulation across organ systems.

After overcoming a decade of debilitating back pain by studying the psychophysiological mechanisms of chronic stress and trauma, Karden deepened his training with neuroplastic specialists such as Howard Schubiner, MD, and in somatic trauma therapies, studying with Bessel Van Der Kolk and becoming a certified Somatic Experiencing Practitioner. Through this integration, he developed a clinical framework for addressing symptoms as reversible neuroprotective responses rather than fixed structural disease. He has since helped thousands of clients worldwide resolve chronic pain, fatigue, and stress-based conditions through applied nervous system retraining.

He co-created HEAL, a structured neuroplastic recovery program that integrates somatic therapies, interoceptive retraining, and trauma-informed approaches alongside cognitive reappraisal and belief restructuring to restore neural circuit flexibility and physiological resilience. By addressing cognitive, emotional, and physiological processes simultaneously, the program targets the full architecture of stress-driven symptom patterns.

Karden has developed and led programming for The Wounded Warrior Project, Starbucks, and the Kripalu Center for Yoga and Health, and is a regular contributor to the Trauma Research Foundation.

He lives in the Berkshires of Massachusetts with his wife and their two daughters.
