Registered Dietitian


Magan Castlebury MS, RD



My name is Magan Castlebury MS, RD and I am a registered dietitian located just North of Denver, Colorado. I completed my Master's    Degree in Nutrition and Food Science from the University of Central Oklahoma in December of 2018 and moved out to Colorado shortly after. Since becoming an RD I have been using my expertise in nutrition to work with clients to make healthy lifestyle changes by looking at their behaviors around food. I believe in tailoring the care to the individual’s specific needs and goals instead of the “one size fits all” approach.



I enjoy working with clients to build a healthy relationship with food by using an intuitive eating approach. This approach to food and nutrition  focuses on behavior changes and teaches clients and patients to be in-tune with their body’s needs. In a world surrounded by the next diet and quick  fix, I am here to break through the diet culture and teach people how to nourish their bodies a healthy, sustainable way. Sports Nutrition is also something I am very passionate about. I have been an athlete my whole life from playing sports all year round in high school, to completing in the National Physique Committee in college as a bikini athlete. If you are looking to improve your performance in the gym or a sport or change your body composition, I can help you dial in your nutrition.
