How to become a registered dietitian

First, dietitians get a bachelor’s degree and must complete approved coursework in areas of chemistry, biology, counseling, food science, and foodservice management.

During this process, they complete a 1200 hour supervised internship, and are then required to pass the Registration Exam for Dietitians to earn the RD credential.

Many dietitians also have their master’s degree and some even go on to obtain their Ph.D. Overall, it takes about 6 to 8 years of additional education after high school to become a registered dietitian.

Registered dietitians are not the food police. We believe in restoring a positive relationship with food and work with you to create a lifestyle that syncs your health goals with the foods and activities you already enjoy.

The key to a sustainable diet is to develop healthy choices that are practical for your unique needs. 

Work environments

Dietitians work in many different settings including hospitals, private practice, public health programs, restaurants and hotels, corporate wellness centers, research facilities, school districts, college campuses, and professional sports teams – to name a few.

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!
