Advanced Nutrition Therapy for Every Stage of Health.

The Mission

Health is your most valuable asset, but navigating the world of nutrition can feel overwhelming. Whether you are managing a new diagnosis, preparing for a major surgical milestone, or seeking sustainable weight loss, you deserve more than a generic handout. You deserve a partner who combines high-level clinical expertise with a real-world understanding of your life.

The Dietitian

I’m Olivia Marrone, MS, RD - a Registered Dietitian dedicated to providing a gold standard of clinical care that is both comprehensive and deeply personal.

My approach is rooted in rigorous academic training in Clinical Nutrition from UC Davis and a Master’s in Dietetics from the University of Rhode Island. With years of experience in high-acuity clinical settings, I provide Medical Nutrition Therapy (MNT) that is as evidence-based as it is empathetic. I’m also deeply trained in Motivational Interviewing, ensuring our work together is a collaboration, not a lecture.

The Integrated Advocate

I believe that nutrition should never exist in a vacuum. To ensure the highest level of safety and efficacy, I provide coordinated care reports for my patients’ primary care physicians. I act as your clinical advocate - helping you interpret complex lab work, navigating the nuances of the healthcare system, and ensuring your entire medical team is moving in the same direction. Whether you are a busy parent or a high-achieving professional, I translate the "clinical jargon" into a clear, actionable strategy.

The Care Model

I believe that elite-level care should be accessible where you are most comfortable. By offering virtual sessions and in-home consultations, I remove the barriers between you and your health goals. My specialties include:

  • Chronic Disease Management: Strategic Medical Nutrition Therapy for heart health, diabetes, hypertension, and kidney health. I move beyond "managing" symptoms to optimizing your labs and your life.

  • Sustainable Weight Loss & Wellness: A science-backed, non-restrictive approach to weight management. I focus on metabolic health and longevity, ensuring your results are as durable as they are healthy.

  • GLP-1 Nutrition & Metabolic Support: Optimizing protein intake and managing medication side effects so you can reach your long‑term goals and sustain them with confidence

  • Pre-Operative Nutrition Optimization: Strengthening your biological "reserve" to ensure a faster, safer surgical recovery with improved clinical outcomes.

The Promise

I don’t believe in "one size fits all." My practice is built on the 1% standard: the highest level of clinical integrity, a non-judgmental approach, and a commitment to helping you thrive in the life you are already living.
