I practice integrative, functional nutrition focused on identifying root causes.
Are you a high-functioning woman 35+ whose digestion has gotten annoyingly unpredictable? Bloating shows up out of nowhere. IBS patterns shift. Hormonal changes make your “usual fixes” stop working. You’ve tried elimination diets and supplements that promised clarity and delivered... nothing. You want a structured, evidence-based plan to stabilize digestion, support hormone-related symptoms, and eat without constant second-guessing. I’ve lived with Crohn’s disease for more than three decades. That perspective informs a clinical approach focused on discernment and durable results, not generic advice or trend-driven protocols.

I am a functional nutritionist who educates people on the benefits of eating certain foods.
I have trained as a functional nutritionist with an integrative approach and believe in foods first. There is a lot we can do with food alone.

I am a nutritionist who has been in your shoes before.

My ideal client is someone who’s ready for real change but feels stuck. Maybe they’ve tried diets, medications, or programs before, but nothing has worked long-term. They may be struggling with weight, newly diagnosed with type 2 diabetes or prediabetes, or managing chronic issues like high cholesterol or high blood pressure. Many are overwhelmed by conflicting nutrition advice and just want to know what to eat — and how to stick with it.
What they really need is a plan that makes sense for their life — not a generic handout or fad diet. They want support from someone who listens, simplifies the process, and keeps them accountable.
