"For the past 20 years, I have been in practice as a licensed Functional Medicine Clinical Nutritionist working day in and day out, to help my patients overcome SIBO (parasites, Candida, dysbiosis, mold, autoimmune, motility issues, mold/ mycotoxin illness, viral load (EBV) and everything else that comes with it). Although I don’t look it, I’m 53 years old. I know how to heal the gut and keep the body healthy, energetic and glowing."

A Proven Approach to SIBO Treatment

If you are watching the summits and researching SIBO and you are more confused than ever, about what this all means to you, I can help you.

There is an overwhelming amount of misinformation circulating about SIBO treatment. For example, the low FODMAP diet does not starve out the gut organisms. If you are stuck on a low fodmap diet, I can help you expand your diet.

If the chatrooms leave you feeling desperate and concerned that you’ll have SIBO forever, I’ll get to the root of why you have SIBO. Let’s get you off this rollercoaster!

If your SIBO treatment has included round after round antibiotic or herbal antibiotics, and ‘it keeps coming back’ I can help you get to the root of why you have SIBO in the first place. Let’s target and address the root cause first!

Affectionately called "SIBO Guru" by my patients, because I do not offer canned approaches.
