About William Civitillo

I became interested in the science of nutrition when I was diagnosed with Celiac Disease at 12. Ever since going on a strict gluten-free diet, the symptoms of the disease started to disappear, and at that moment, I became fully invested in the field of nutrition and the lasting benefits it can bring. I received my Master’s in Dietetics from Saint Elizabeth University in Morristown, NJ, where I also completed my Dietetics Internship. I completed my undergraduate program in nutrition at Keene State College in NH. I currently work full-time as a Bariatric Registered Dietitian at Nassau University Medical Center in Long Island, NY. I self-published a book through Amazon called Life Through A Device, which teaches and advises readers about making healthier and simpler choices in life. Through telehealth and other online and face-to-face practices, I can utilize this type of counseling in a broader way to reach anyone throughout the United States. I am currently based in NY and have my dietetics license curtailed to the educational department based in New York City. A license is not required for this provider to see patients. This provider holds a Registered Dietitian certification with the Commission on Dietetic Registration.
