Welcome To The


The GI-MAP® Mastery practitioner training course is a clinically-relevant program designed to help practitioners confidently navigate the GI-MAP® to become an expert at interpreting this test and at developing foolproof client protocols and hence more word-of-mouth referrals.

The GI-MAP® Mastery course will take your gut health knowledge to the next level allowing you to better serve your clients and build your practice.

Once you get the gut right in your clients so many of their symptoms will disappear and they will be singing your praises from the rooftops. 

If you don’t address the gut though, you are leaving a gaping hole in your clients' protocols and ability to get better.

Are you . . . 

Running the GI-MAP® in practice but still have so many questions about how to use it to best help your clients?

Considering running the GI-MAP® in practice, but don’t know how to start interpreting it and building out relevant client protocols?

If you answered “yes” to either of the above questions then the GI-MAP® Mastery practitioner training course is for you.

This course is for you if:
  • You are a nutritionist, FDN-P, Naturopath, Nurse Practitioner, Dietician or other designated wellness professional who has access to the Diagnostic Solutions GI-MAP® and you run it in practice or you want to offer it in practice.

  • You’re overwhelmed when you look at your clients’ GI-MAP® results and don’t feel completely confident in your ability to untangle what all the markers mean and come up with a solid plan to help your clients get the results they seek. 

  • You don’t believe that the current protocols you’re using in practice are driving the results your clients should be achieving, and you’d like to find some foolproof methods in order to better help your current clients, get more referrals, and achieve a thriving practice.

What you’ll learn in the course:

    All about each individual GI-MAP® marker on the test - what it means and how to address it if necessary.

    Why we need to move away from the narrow-minded antimicrobial “killing” focus and instead work toward shifting the microbiome back into better balance using diet, prebiotics, and working on terrain.

    What to do if your clients’ GI-MAP® results show infections like H. pylori, giardia, parasites and others: where to start and what protocols to use, (you will be given all the protocols I use in practice).

    We’ll do a very deep dive into H. pylori.

    How to prevent reinfection with H. pylori / parasites etc, once your client stops their protocols.

    Why probiotics are not the be all and end all, and why prebiotics are an even better choice in many situations and should be a part of almost all your gut healing protocols. We’ll dive into which prebiotics are best for various situations.

    What some of my favourite supplement brands are, based on my years of clinical practice and the 100’s of GI-MAP® tests I have run, and when to use them.

    In what order to address infections that pop up on your clients’ GI-MAP®.

In the GI-MAP® Mastery practitioner training course you get 3 hours of training. No fluff. Just clinically relevant information and applicable strategies that work to help serve your clients and build your confidence, your business, and your revenue.

This is what you get inside the 

1.  13 modules covering every marker on the GI-MAP® - what the markers are, how they relate to your clients’ clinical presentation and symptoms and what to do if they’re high / low.

Functional Health Coach, Integrative Nutrition Coach & Women’s Health Educator

"As a Functional Health Coach, I’ve purchased many courses over the years to learn how to interpret a variety of functional tests. When Tara shared that she was creating a GI-MAP course, I couldn’t wait to get my hands on it. 

Not only is Tara an exceptional clinician, but she’s a wonderful teacher.

Tara’s passion and excitement is palpable - she’s very engaging as she guides you through the course. I love that each video is short and to the point (under 20 minutes each). As a busy practitioner, time is precious! I appreciate how succinct she is and that she provides PDFs of all the slides.

She also includes PMIDs, case studies, and protocol suggestions, which is invaluable. It can feel overwhelming to create protocols and choose from the surplus of supplements on the market.

And as if the course wasn’t enough, Tara offers a support group where you can post questions and get feedback on client cases - so incredibly helpful!

If you’re thinking of purchasing the course, don’t hesitate - it will be money well spent. You’ll feel confident in offering the GI-MAP test to clients and will likely become a standout practitioner."

My promise to you.

Once you’ve completed the GI-MAP® Mastery practitioner training course you will:

•  Understand what every marker on the GI-MAP® means and how it pertains to your clients’ case
•  What to do if the marker is high / low / or present in any capacity on the GI-MAP®
•  Which protocols to use for each infection that pops up on the GI-MAP®
•  In what order to address infections that pop up on the GI-MAP®
•  Feel confident in developing client protocols based on their GI-MAP® results
•  Be connected with a community of like-minded colleagues all looking to better their skills and get answers about client cases


Please note, the GI-MAP® taught in this course is from Diagnostic Solutions laboratory. No other stool testing from other labs will be assessed in this course.
