I specialize in Irritable Bowel Syndrome and complex gut issues that haven't responded to standard approaches. I work with people who are still struggling after trying low-FODMAP or elimination diets and who want to understand why their body isn't responding to move beyond restrictive diets and feel better.
As a Registered Dietitian with a Master's in Nutrition & Functional Medicine, I look beyond food choices to assess digestion, nutrient status, and the microbiome. This is how we find the root cause and build a plan for healing.
My clients typically come to me with some combination of bloating, cramping, urgency, constipation, or diarrhea that hasn't resolved despite consistent effort, and confusion or fear around food after years of conflicting advice. Often, they've seen gastroenterologists and multiple providers without getting a clear answer.
Clients tell me the biggest relief isn't just feeling better physically — it's finally understanding what's been going on and having a real path forward.
I offer a free 20-minute call to see if we're a good fit and verify insurance coverage.
