You might feel like you’ve tried every diet, every plan, every reset, but still feel stuck. Maybe you’re constantly thinking about food, swinging between feeling in control and overwhelmed. You’re tired of the guilt, the spirals, and the all-or-nothing mindset. My ideal clients are often high-achieving women struggling with restrictive eating, emotional eating, binge eating and/or body image concerns. Many come to my practice feeling exhausted by food rules and frustrated that nothing seems to “work” long term. Others feel disconnected from their hunger, fullness, and ability to trust themselves around food.

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.

I use functional nutrition, hormone mapping, and microbiome science to find what’s driving your symptoms so you can feel better, lose weight, and finally see real, lasting results.
I help stabilize blood sugar, reduce insulin resistance, improve liver markers, restore cycles in PCOS, support sustainable weight loss, and increase energy. Clients see measurable changes in labs and daily symptoms. I’m not a traditional dietitian. I create a personalized metabolic roadmap based on your unique patterns, not generic advice.

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.
