I’m Aeryn O’Halloran, a nervous system educator and certified mind-body practitioner specializing in chronic illness support alongside medical care. Over the past few years, I’ve supported individuals navigating complex chronic conditions, refining a structured protocol.

What led me into this work wasn’t a career plan, it was direct experience inside a body managing complex chronic illness and CPTSD. I navigated POTS/dysautonomia, post-viral syndrome, ME/CFS, MCAS symptoms, and trauma-related nervous system dyfunction within a medical system that struggled to account for the full complexity of my symptoms.

Living inside that kind of body, (exhausted, reactive, overwhelmed), showed me how trauma physiology can masquerade as illness, how illness can mimic trauma, and how the two weave together.

My work integrates neuroscience, nervous system education, and somatic sensory practices to help people reduce symptoms and rebuild baseline stability. The Baseline Recovery Protocol™ is designed to be practical, structured, and paced so your system can shift without being further overwhelmed.

  • I believe transparency matters, especially in a field where so many people have been dismissed, misunderstood, or misled. I am not a licensed medical or mental health provider, and I do not diagnose, treat, or promise the resolution of any condition. My work is educational and nervous-system–informed, drawing from trauma-informed training, contemporary models of autonomic regulation, somatic practices, and holistic health principles. Everything I teach is designed to complement , not replace,  your existing medical care.

    My role is not to act as your clinician, but to serve as a guide; someone who helps you better understand your body, reduce overwhelm, experience fewer flare-ups, and advocate more confidently with your medical team.
