Get To Know Marissa

I graduated from CUNY-Queens College in 2015 with a Bachelors in Science with a concentration in Nutrition and Dietetics. While completing my DPD program, I was an active member of The National Academy of Nutrition and Dietetics, Phi Upsilon Omicron Honors Society, Queens College Dietetics Club and The Long Island Academy of Nutrition and Dietetics.

Post-college, I served on the board as Public Relations Chair for The Long Island Academy of Nutrition and Dietetics. While serving my term, I attended various health fairs at community centers, schools, hospitals and other organizations throughout Long Island providing nutrition education to various populations in need. 

I decided that I wanted to teach nutrition education beyond my local community and expand my horizons. In the summer of 2016, I volunteered with Tanzania Education Corporation. Myself and a team of four dietitians spent one month in Karatu teaching nutrition to elementary school children and teachers at Tumaini Junior School. We found that the school children were deficient in protein which is essential for many bodily functions including growth. We ventured into the local marketplace to find what was available to the school and local community in terms of nutrition and affordability. We worked with the school cook to incorporate protein into traditional Tanzanian meals. 

As for my professional career, I started as a dietitian in a sub acute care facility working with the older adult population in preventing disease progression, (metabolic syndrome -hypertension, end stage renal disease, type-2 diabetes, etc.). Partnering with my patients, we worked together to create meal plans and develop goals and interventions to help improve their nutrition status.

Following my time in the sub acute care facility, I transitioned into the hospital setting and worked at Northwell Health, Huntington Hospital on Long Island where I worked in dietetics management. My job was to oversee the food service employees and ensure that patients were receiving appropriate meals based on their medical condition. 

In 2020 I started my dietetic internship through Northwell Health. I completed over 1400 hours of supervised practice and research at North Shore University Hospital in Long Island. The program's focus was in medical nutrition therapy. I rotated through various floors of the hospital including oncology medicine, GI surgery/bariatrics, geriatrics, maternity, neonatal intensive care unit, medical/surgical intensive care unit, cardiothoracic care unit, and more.

Over the past year I have worked as a Clinical Registered Dietitian Nutritionist at various long-term Health care facilities in Long Island, New York City and Upstate New York. I recently moved to Jersey City and I am currently working for a sub acute rehab care center with the older adult and geriatric population while pursuing my masters degree online at Stony Brook University School of Medicine. My concentration is in Integrative Nutrition Therapy.


I believe in a whole-foods, whole-person approach to nutrition and health by combining both my training in medical nutrition therapy with components of integrative and functional medicine into a plan for success for each of my patients.
