Walter Crinnion ND

Walter J. Crinnion ND graduated with the first class at what is now, Bastyr University (then called the John Bastyr College of Naturopathic Medicine) in Seattle, Washington in 1982. While there, he had the privilege to have Dr. Bastyr, Dr. Bill Mitchell and Dr. Joe Pizzorno as teachers, mentors and, ultimately friends. Naturopathic medicine is based upon a handful of principles that include: Treat the cause, the healing power of nature and doctor as teacher. He embraced all of the principles and soon began to explore why some patients were not getting better when safe and powerful natural healing techniques were used. He soon realized that the cause of some illnesses were due to an overload of environmental toxicants. Since no one had begun to teach this aspect of medicine in medical schools, he began to search diligently through all the published medical journals and medical conferences to find answers. 

Now with over 30 years of medical practice, he is considered one of the foremost experts in the field of environmental medicine. He started the environmental medicine classes at Bastyr University, University of Bridgeport College of Naturopathic Medicine, and the Southwest College of Naturopathic Medicine (SCNM). He was a professor and chair of the Environmental Medicine department at SCNM from 2003 – 2013.. He also does twelve-month training courses for licensed healthcare providers who wish to become more proficient in environmental medicine. He founded 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 lectures acrossNorth America and Europe at medical conferences where he is a sought-after speaker.

His first book: Clean, Green and Lean was published by Wiley & Sons in 2009, and is an excellent overview of environmental medicine and how to lower your burden of environmental toxicants and regain your health. He has been a guest on ABC’s The View three times with Barbara Walters in 2001, talking about toxic compounds in our everyday environments and how to protect ourselves. Dr. Crinnion was also asked by the Huffington Post to be a blogger on their site, providing all of their readers with current and accurate information about health and the environment.  He is the editor of the environmental medicine section of the journal, Alternative Medicine Review, and has been appointed to the editorial review boards of the New England Journal of Medicine, Pharmaceutical Biology, Science of the Total Environment and the International Journal of Hygiene and Environmental Health.  Dr. Crinnion has also authored over 25 articles that have been published in peer-reviewed journals (available on PubMed).  He has also helped to create laboratory panels that have become the standard of care for detecting environmentally –induced illnesses and has also turned his prodigious talent toward making unique dietary supplements that are some of the most active and powerful supplements available in the market to date.

Robert Streit


Robert is native of northern Iowa and was raised on a crop and livestock farm. He graduated from Iowa State Univ. with degrees in the Ag Sciences. Robert worked four years with the country’s largest crop consulting firm before moving into twenty years of agronomy advising with two major seed firms. After several mergers he moved back into private Ag consulting working with individual farmers in the Midwest and as an advisor to several technology and biological companies across the globe. Robert began his international work after being selected to work on the USDA rust task force. This led him to projects in several South American and European countries, as well as to China and Russia. During those projects he has toured and visited with scientific staffs of several major Ag input companies.

In the past eight years besides managing his two jobs he has been involved in working with and helping to educate audiences and individuals on the correlation between healthy soils and the production of healthy food and how it relates to good human health. This has involved projects on soil remediation, making biological assessments of growing environments, developing systems to clean up food and water supplies, and trialing products used to clean up systems and bodies. Part of this information is relayed thru his weekly Ag column and press articles.

Robert and Carol have six kids with most having graduated with their BS and graduate degrees.
