About Us

Danielle Fatemi, MS, RDN, LD


I am a Registered Dietitian Nutritionist, (RDN), mother of two, marathon runner and a frequent kitchen experimenter. I've been working in both clinical and private practice for 10 years. I relocated to Southern California from Washington, D.C. with my family in 2015 and I truly enjoy helping people in Ventura County, Conejo Valley and online. I have a strong passion for helping others, so I started Optimize Nutrition in 2007 to help people meet their nutrition-related goals. I have over a decade of clinical and hospital work at The University of Virginia Health System, Texas Children's Hospital in Houston, TX and most recently at The National Institutes of Health in Maryland, I am well trained in many areas of clinical and even critical care nutrition. My biggest enjoyment is focusing on wellness, weight management, sports nutrition, heart healthy nutrition, food allergies, pediatric nutrition and feeding issues and cancer nutrition.
