Marissa Sharkey: RD, business owner, cat mom and Halloween enthusiast

I’m a Registered Dietitian, and I’ve been helping people transform their nutrition and health for more than 9 years.

My journey into dietetics wasn’t a straight line—I originally thought I’d go into cosmetology, but quickly realized my real passion was food, health, and helping people feel their best. I earned my degree in Food and Nutrition with a concentration in Dietetics from the College of Saint Elizabeth in 2016, completed my supervised practice of 1200 hours at Cedar Crest College, and became a Registered Dietitian in 2017 after passing the national exam.

I started out working at a New Jersey hospital, mainly with ICU patients, where I discovered how much I love nutrition support and tube feeding. Over time, my work shifted into telehealth, where I’ve been for the last couple of years. Now, I get to support people with GI conditions, tube feeding, women’s health (like PCOS/PMOS and menopause), balanced eating, body image, and cardiac disease. My approach is all about making nutrition feel realistic, sustainable, and personal; because there’s no one-size-fits-all way to be healthy.

When I’m not working, I’m probably hanging out with my two cats, Graycie and Finnegan. I love lifting weights at the gym, traveling (Australia is on my bucket list!), attending concerts, and diving into a good book (spicy romance novels are my jam). Halloween is my favorite holiday as you can see and yes, that is a 12 foot Jack Skellington in my yard!

The house is decorated with spooky Halloween decorations, including a hanging ghost with a pumpkin head and a fabric banner. It's dusk outside.
