Welcome to The Digestion Coach ™

With 36 years of experience, I am highly confident in treating gut and digestion problems.

The Digestion Coach ™: A Pioneer in Gut Health Solutions

In 2008, I made internet history by posting the first “Biofilm Protocol for Lyme and Gut Pathogens” and “The H. pylori Protocol”. These guides have helped people better understand and fight challenges from the stomach bacteria H. pylori and biofilm. Since then, I have kept researching, writing, and helping people worldwide. One of my goals is to share tips and tools to keep your digestive system healthy. Plus, I use my functional medicine, clinical nutrition, and diagnostic skills to help people from all walks of life fix their health challenges. I focus on discovering and correcting the root causes, not just masking symptoms, because I 100% believe your body can heal with the right support.
