Hi, my name is Amanda Haney. I am a registered dietitian, board-certified nutrition support clinician, Cal State Long Beach alumnae, and former pediatric clinical dietitian. Currently, I am working as a project manager at Children’s Hospital Los Angeles. As a clinical dietitian or in my current role, my passion is working in a diverse setting with a variety of teams in order to improve patient outcomes and achieve better health for the families in my community. I became a dietitian because I love food and I love medicine. There is so much misinformation about nutrition in the media, so I enjoy creating educational content that makes nutrition simple and to make your health goals achievable. In my free time, I love soaking up the beauty at the beach, riding my bike, staying active, cooking, and, most of all, spending time with my family and friends!
