Who is it for?

Licensed health care providers who wish to improve their ability to identify which of their clients have health issues due to a toxicant load, and then to know how to properly treat them.

Do I get CE credits for the course?

71 hours of Naturopathic Medical CE (including 10 hours pharmacy) has been approved through the Oregon Board on Naturopathic medicine.

When and where does this course occur?

This class combines distance learning, and four weekend meetings (held quarterly).

Distance learning is accomplished in the convenience of your own home or office through an online learning platform . Instead of trying to retain as much as possible in a long weekend, you can learn it at your own pace.

The practical application of the material to real patients from your practice, and the practices of other course participants, occurs during the weekend gatherings. The weekend gatherings are held quarterly and you can attend as they fit your schedule, although doing them within a 12-18 month timeline is recommended.

Weekend Case Work 

Weekend Gatherings (4 are required for course completion)

(Each weekend has a total of 12 hours of Case work, Questions and Answers, along with an occasional guest lecturer, providing 48 hours of CE over the course of the class)

The weekend gatherings are focused on providing students the opportunity to acquire expertise in the practical clinical application of all that has been taught. Utilizing cases from their practice and the practices of the other students the effective methods for properly diagnosing and treating environmentally ill persons will be repeated experienced – along with the nuances that can only be found with real clients. By the end of the fourth weekend it is expected that the majority of the students will feel some degree of proficiency at diagnosing and treating environmental illness

Case Studies

Each physician attending the class is required to bring a minimum of three cases from their practice to share with the class. This allows all the members of the class to work on the application of the class information on real patients. As the class progresses the cases are brought back to successive weekends so that all can benefit from the progress and subsequent questions about the case.

Questions and Answers 

Time is allowed on both Saturday and Sunday to cover questions that the participants have from the lectures. This often results in a lively discussion and is often considered by the participants the best part of the weekend, as these discussions are always highly clinically relevant.



What will I learn in this course?

By the end of this training the participants will be able to:


  1. Describe the classic signs and symptoms of toxic burden as then present in the average patient.
  2. Be able to categorize the most likely classes of toxicants for the patient based upon the patients’ signs and symptoms.
  3. List the most common sources of toxic exposure for their patients.
  4. Assist the patient in understanding how and where these toxins came to be present in their bodies.
  5. Determine which, if any, laboratory measurements would be assistive in the workup of a toxin-burdened patient.
  6. Identify any genetic polymorphisms that may have led to the patients overburden.
  7. Devise a list of action steps for the patient to avoid further exposures that would exacerbate their health problems.
  8. Devise a list of dietary changes and supplementation that would be most beneficial for their patient.
  9. Devise for the patient a cleansing program to help them reduce their toxic burden and assist them in accomplishing it.


The class is limited to 30 participants


Faculty: Walter J. Crinnion ND

Registrations are recommended to be completed at least 6 weeks prior to your first weekend. This date will allow each participant sufficient time to utilize the study materials prior to the first weekend.


Tuition for the 12month program is $3,950.00 that will include all handouts.  (See registration form for payment options).


Once your registration is received you will be provided an access link to the online learning platform.

Basic Schedule


This training is for licensed health professionals seeking to develop expertise in the field of Environmental Medicine. The curriculum for this training is designed to provide clinicians with the requisite information to properly identify and treat environmental illness. Each weekend session will include time for case histories and case presentations from the participants’ practices, discussion of difficult cases and group-decided topics. It is very important for each participant to bring at least one case history from their practice to work with over the course of the class. Each participant will be encouraged to complete toxicity testing on themselves (special prices on toxicity testing are available to each class member).
