Build your IBD nutrition knowledge, grow your business & change lives.

Millions of people have Crohn's disease and ulcerative colitis, and they struggle to eat and enjoy food. They need help from knowledgeable professionals. We know there are many RDNs who WANT to counsel IBD patients but don't feel comfortable due to lack of experience. 

That's why we created this course... 

If you are seeing or want to see more IBD patients (and they need you!), this comprehensive course (made up of >15 years clinical experience) will give you the tools and confidence you need to help your IBD patients feel better using food and nutrition.

"This is a much needed course that fills a void in the world of IBD nutrition. The up-to-date blend of readings, videos, handouts and diagrams keeps the content fresh and meets many learning styles. New and seasoned dietitians will benefit from this course. Very well done!"

Outstanding Teacher!

Ellen Scherl, M.D. Gastroenterologist at the IBD Center at Weill Cornell Medicine

“Colleen is an expert on how to eat with Crohn’s and ulcerative colitis. Since we began working together in 2011, I’ve seen significant improvements in our patients’ quality of life. She’s an outstanding teacher and appreciates the challenges associated with eating with IBD.”

Above and beyond any training course out there!

Danielle Staub, MS, RD, CDN & GI Nutrition Expert

"This course is an excellent resource for RDNs. It goes above and beyond any training course out there and provides the most up-to-date research as it relates to IBD nutrition. The information is laid out clearly, concisely and includes valuable case studies and endless patient resources, which will help RDN’s put the information into practice. The experience the instructors bring to this course is invaluable. I absolutely loved this course and believe it will be a great tool for other RDNs looking to expand their knowledge in this area."
