Walter J. Crinnion, ND, graduated from the John Bastyr College of Naturopathic Medicine in Seattle, Washington in 1982. Dr. Crinnion embraced all of the principles of naturopathy and began to explore why some patients were not getting better when safe and effective therapies were being used. Upon realizing that the underlying cause of some illnesses was due to an overload of environmental toxicants, Dr. Crinnion dedicated his career to understanding this aspect of medicine.
With over 30 years of clinical practice, Dr. Crinnion is considered one of the foremost experts in the field of environmental medicine. Dr. Crinnion started the environmental medicine classes at Bastyr University, University of Bridgeport College of Naturopathic Medicine, and the Southwest College of Naturopathic Medicine (SCNM). He also founded and chaired the department of Environmental Medicine at SCNM (2003-2013), and the Naturopathic Association of Environmental Medicine – a specialty board for practitioners in this field that sets standards of care and provides board certification in this area. Dr. Crinnion was involved in the development of laboratory panels that have become the standard of care for detecting environmentally induced illnesses, and has authored over 25 articles published in peer-reviewed medical journals. Walter Crinnion authored Clean, Green, and Lean: Get Rid of the Toxins That Make You Fat (Wiley, 2010), and co-authored Clinical Environmental Medicine: Identification and Natural Treatment of Diseases Caused by Common Pollutants (Elsevier, 2018).
Working together with colleagues from International IV Nutritional Therapy for Physicians, Dr. Crinnion co-developed and delivered certification courses on Heavy Metal Assessment and Chelation Therapy for health care professionals in the US, Canada, the UK, Mexico and Taiwan.
In 2004, Walter Crinnion was awarded ‘Physician of the Year’ by the American Association of Naturopathic Physicians (AANP) for his individual achievements and leadership.
