SIBO and Beyond: Help for Root Causes, Tough Cases, and Stubborn Symptoms Masterclass Summit

Learn What Expert Doctors Do When The Standard SIBO Treatments Alone Aren’t Enough

Feel like you’ve tried it all for SIBO… but your health still isn’t where you want it to be?

It’s time to go beyond SIBO (Small Intestine Bacterial
Overgrowth) and talk about what else may really be going on
and complicating (or stalling) your healing journey – and how
you can address and heal these issues for your best health ever!

Join SIBO expert, Dr. Allison Siebecker and SIBO Author, Shivan Sarna for this 16 Masterclass Summit...

covering everything ELSE you need to know when handling stubborn SIBO cases and other tough health issues.

These problems can mimic, co-exist, and even cause SIBO.

That means, even if you’re doing “everything right” for SIBO, they could be stopping you from getting better.

Even if your treatment protocol is perfect, you’re an expert in getting tested, and you know all about preventing relapse – there still might be more to your SIBO journey to uncover.

These are the surprise, under-discussed issues that make healing from SIBO far from straightforward – and leave so many people frustrated and discouraged.

It’s time to change that!

Bottom line: If you’re not learning about how to address these issues, you might be leaving your (or your patients) health on the table.

Now, you can learn about them from trusted, expert doctors – in the comfort of your own home, on your own schedule!

If you haven’t been able to resolve your chronic case of SIBO, this is a must-attend event.

What People Say About Our Masterclasses

"The content Shivan and her team creates is leaps and bounds above anything else you will find online. As a patient I feel so empowered to collaborate with my providers because I am actually able to understand what is going on in my body thanks to these classes and videos. These masterclasses dive deep into the current understandings of SIBO, gut issues, and other comorbidities. I literally can not imagine where I would be without her and all of this content."

~ Ann


“The class was extremely thorough. I found affirmation that I have many of the common underlying causes for SIBO. I learned about many more causes I wasn't aware of.”

~ Betty


"I’ve been learning how to treat my SIBO for a few years, but attending this summit completely transformed the way I will look at treatment going forward. I didn’t know so many of these SIBO-related issues and conditions existed and how much of an impact they may be having on my SIBO. Thank you again to Shivan and Allison for bringing this information to light.”

~ Vicky


“Thank you so much Shivan and all involved. I am thoroughly enjoying all the summits and all the talks that are available. Keep up the good work. In South Africa finding the information that I get from your summits keeps me substantially ahead of any other diagnostic doctors in this country. Cutting edge.”

~ Frans


“A huge thank you to Dr. Siebecker and Shivan. I finally have hope. There were so many questions I didn’t even know I had. Now I have clarity and know that healing is possible.”

“The slides and content were incredible. I’m so relieved knowing how much the fungus among us has been impacting me. Thank you SO MUCH for helping me discover how to treat symptoms that have been such a burden for years. ”

~ Beth


“For years, I’ve just heard over and over again that I have IBS without any real explanation of what that means or treatment options. There have been moments when I felt like my IBS was controlling my entire life. Being introduced to SIBO and other specific gut health issues in this summit has given me hope that I can change my life and live without symptoms. I’m getting a breath test THIS WEEK! And even if I don’t have SIBO, I now know so many other conditions I can be testing and looking for to finally get diagnosed with something real and make a plan. I can’t thank you guys enough. I’m adding the courses to my library and signing up for the next one.”

I have learned so much from what to eat (more choices than I thought I had) to what to do next in my treatment. WOW. Thanks for the discount too! I had wanted to buy some of these masterclasses but my budget had kept me from them. Now, I can't afford NOT to buy them."

~ Monica


“Thank you for putting this together! In four days, I learned about mold, fungus, MCAS, and so much more. As a health coach and advocate, this will not only help me but help my business and clients.
