Ryan Whitcomb, MS, RD, CLT

"We are all biochemically different and therefore, we each require a different way of eating."

I treat the whole person.

Ryan Whitcomb is a registered dietitian/nutritionist who uses an integrative and functional medicine approach towards optimizing health.  His primary specialty is treating those who suffer from Irritable Bowel Syndrome, a chronic digestive disorder characterized by abdominal pain, gas, bloating, diarrhea and/or constipation.   

Integrative and Functional Medicine uses a “whole-person” approach to treating disease.  It takes into account your entire lifestyle, not just your diet, while trying to understand the root cause of disease rather than attempt to minimize the symptoms.  By determining the source(s) of imbalance, an intervention is then established to correct the underlying issues.

I only work with motivated individuals.

If you’re committed to getting better and determined to turn your life around, contact me today or schedule a free phone call to discuss your situation. 

That said, I don’t work with everyone.  If you are unable or refuse to make dietary and lifestyle changes, then my services are not for you.  If you’d rather “live with it” because it’s easier, my services are also not for you.   

I provide nutritional counseling to clients from around the United States and abroad.  Sessions are conducted either by phone or online (video), depending on your preference.
