"Wonderful course, so well structured and presented. Each lesson was so packed with actionable information and insights. This took what I had learned during my one year residency/internship to a new level, which I appreciate. I now have a good grip on the complexity of the science and the challenge of working with each patient's completely unique journey/challenges. I really appreciate the pace, delivery and passion that was palpable in every lesson. I'm so glad for the opportunity to participate and learn." ​

About Dr. Siebecker          Instructor Qualifications -  Allison Siebecker, ND, MSOM, LAc


Dr. Siebecker is Instructor of Advanced Gastroenterology at NUNM, the 2021 lifetime achievement Borborygmus award recipient from the Gastroenterology Association of Naturopathic Physicians, and the original force behind SIBO awareness and education in the Naturopathic profession.

Clinical Experience  Dr. Siebecker has specialized in SIBO since 2011, treating only SIBO patients in her practice and serving as a second and third opinion referral doctor for patients who have failed previous treatments. This perspective has allowed her to identify pitfalls in SIBO care and how to overcome them to increase success (which she shares in her teaching).

Teaching Experience  Dr. Siebecker created and began teaching the first-ever SIBO curriculum at a medical university (Advanced Gastroenterology at NUNM) in 2013. She's been teaching physicians, medical students and patients internationally since 2010 - through conference lectures, online classes, podcasts and her free educational website She has taught over 6,000 students in continuing education conferences alone (see list below). Many of her students and patients have gone on to become SIBO specialists and teachers, teaching alongside her at conferences and in their own SIBO courses, websites and books. Her teaching style is informal and friendly, with a focus on making the complex understandable.

SIBO Pioneer  Dr. Siebecker first introduced SIBO to the Naturopathic profession in 2010 at the annual AANP conference. In 2011, Dr. Siebecker created the first online resource for SIBO, the free informational website In 2011, to help patients who couldn't afford elemental diet treatment, she created the Homemade Elemental Diet Recipes and co-created the Herbal Antibiotic SIBO protocols, both offered for free on and used by thousands today. In 2012, to help SIBO patients struggling with what to eat, she created the SIBO Specific Food Guide (called the SIBO Diet by most) also offered for free on Her diet has been adapted into other SIBO diets by former students/colleagues. She co-created the first SIBO specialty clinic in 2013 (SIBO Center for Digestive Health at NUNM); the first-ever SIBO conference in 2014 (NUNM SIBO Symposium); and the first online-only SIBO conferences in 2017 (SIBO SOS Summits). Dr. Siebecker continues pioneering - her 2020 SIBO conference, Next Steps for Treating Tough SIBO, was the first focused exclusively on treatments for recalcitrant SIBO.

"One of those doctors who straddles the worlds of education, research and clinical practice with apparent ease and generosity towards those who wish to learn from her."
- Dr. Penel Houghton
