Meet the team



Hello, my name is Lellieth Keize; you can call me Lilly. I am the owner and founder of Keize Nutrition Keys LLC. I am a Registered Dietitian-Nutritionist, certified Weight Management Specialist, Certified Diabetes Care & Education Specialist, and a National Diabetes Prevention Program Lifestyle Coach. I hold a Master's degree in Diabetes Education and Management from Teacher's College Columbia University, a Bachelor of Science in Nutrition & Dietetics from the University of New Haven, and a Bachelor of Science in Corporate Communications Degree from Southern CT State University. I currently work as the Diabetes Program Coordinator at Norwalk Hospital Nuvance Health, where I educate individuals with type 1, type 2, and gestational diabetes as to how to manage their disease. I spent most of my career educating individuals on diabetes management, cardiovascular diseases, weight management, renal disease, disease prevention, and helping people make healthy lifestyle changes. 

I am passionate about nutrition, health, and wellness. With more than a decade of experience in multicultural nutrition counseling, I help individuals continue to enjoy their ethnic foods but make healthier choices to suit their dietary needs and lifestyles. I enjoy cooking, reading, meditating, hiking, and taking long walks around my surrounding area. I believe in giving back to my community and feel empowered when people's health and physical needs are met.

“Those who think they have no time for healthy eating, will sooner or later have to find time for illness.” – Edward Stanley
