Hi, I’m Colleen!

I work with patients, doctors, nutritionists, educators and students who are looking for expert advice on food, nutrition and gut health. My nutrition services and products give them exactly what they want, which is to learn how and what to eat to improve digestive health and maximize quality of life.

You can learn all about my professional experience at the bottom of this page, but here are a few highlights:

I have 11+ years experience counseling people with gastrointestinal (GI) issues on what to eat. I’ve worked with thousands of people with mild to complex gastrointestinal issues.  

I specialize in working with people with inflammatory bowel disease (IBD), including Crohn’s disease, ulcerative colitis and pouchitis. I created the nutrition program at the Jill Roberts Center for IBD at Weill Cornell Medicine in New York City. 

I’m an adjunct professor at New York University where I teach the “Diseased Gut” course for graduate students. Students have described my course as “fantastic” and “my favorite course.”

And when I’m not writing, teaching, public speaking, counseling, and creating useful products, I’m nerding out on gut microbiome research. Oh, and romantic mysteries (shh!). 

If you want to know more, here are 5 things you probably don’t know about me …


  1. My first job after college was in print media, and that’s where I met my husband.
  2.  I was voted the NYC Crohn’s and Colitis Take Steps Healthcare Hero in 2017.
  3. My favorite job in the world is being a mom. 
  4. I was a contestant on Cash Cab. Before you ask, I didn’t win.
  5. My favorite girl scout cookies are Thin Mints. It might have something to do with my mom eating a whole box of them in one sitting when she was pregnant with me.
