Nutrition Therapy Nutritionists and Dietitians in Sag Harbor, NY
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.

My philosophy centers on one simple, powerful truth: the gut is the foundation of health.
You’re not alone if you feel trapped by symptoms yet routine labs were normal. Or you’ve been given medication, acid blockers, antidepressants or vague advice like “try eating better” without anyone asking why you have symptoms in the first place.
I’ve been there too and I know a better way.
My approach focuses on finding the root cause of your health concerns through deeper testing to answer key questions:
What’s driving the inflammation?
Is the gut lining compromised?
Is the microbiome balanced?
Is the body absorbing nutrients properly?
