About Marissa

Hi, I'm Marissa. I'm a Registered Dietitian based in Costa Mesa, CA, with six years of experience helping people build healthier relationships with food. I earned my MS in Human Nutrition from Stony Brook University, and most of my practice has been in clinical and hospital settings where I saw how nutrition intersects with people’s everyday lives. Outside of work, I love hiking, cooking, and spending time with my family. I believe in meeting you where you are and helping you build sustainable habits to achieve long-term health benefits.

Approach to care

My care philosophy honors partnership, is grounded in current science and takes a warm, nonjudgmental stance. I lean on evidence-based practices and translate them into practical steps you can use. We'll work together to build lasting habits rather than quick fixes, honoring your pace and values. Education guides every session so you feel empowered to make informed choices that fit you long term.

Your first session with Marissa

Our first appointment is all about you. We'll create a warm, judgment-free space where you can share what's brought you here, a quick look at your medical history, and what you want to change. You don't need to have it all figured out yet. We'll review your history and goals together and set 1 or 2 realistic, short-term steps to start with. You can expect collaborative conversation, practical guidance, and a plan that respects your life, schedule, and pace. I look forward to meeting you and supporting you as we start this journey.
