Every year, on the second Wednesday in March, we celebrate Registered Dietitian Nutritionist Day: a time to recognize the impact of RDNs in the field of nutrition and healthcare. As I reflect on my own journey, I’m reminded of how far I have come – from not even knowing the field existed, to getting my Master’s degree and pursuing my passion.
The Beginning: Choosing the Path
Going into college I thought I would become a teacher or a psychologist. It wasn’t until I took a human biology class as a general education requirement that I even knew what a dietitian was. I had been interested in food and nutrition for many years, and I knew I wanted a career in a field that would help others. While I felt like dietetics was a 180° turn from education and psychology, I soon realized that it actually incorporates both, plus the science of nutrition.
The Challenges and Growth
Becoming a dietitian is no small feat. First you have to survive the rigorous coursework of your undergraduate degree. Then you endure the competitive internship matching process. The dietetic internship is a challenging and rewarding learning experience, basically thrusting you into the field. Finally you face the ultimate test: the RD exam.
The learning doesn’t stop there. Although it is now a requirement, a Master’s degree was optional when I became a dietitian. I completed my Master’s degree in 2024 in Nutrition Education to stay competitive in my field and to sharpen my education skills. Continuing education is a requirement for all dietitians, and is especially helpful for dietitians who end up wearing many hats during their careers. Over the 12 years since I passed my RD exam I’ve worked in eating disorders, long term care, dialysis, and weight management. Each experience has shaped me, teaching me new skills and reinforcing the value of our profession.
One of the biggest lessons I’ve learned is that nutrition isn’t just about numbers and nutrients—it’s about people. It’s about meeting them where they are, understanding their challenges, and helping them make realistic, sustainable changes.
The Evolution of Nutrition and Dietetics
Since becoming a dietitian, I’ve seen the field evolve in ways I never expected. From the rise of intuitive eating and weight-inclusive care to the impact of social media on nutrition messaging, our profession is constantly adapting. As dietitians, we are the trusted experts in a sea of misinformation, and that role has never been more important.
Looking Ahead
As I celebrate another RDN Day, I feel grateful for the opportunities this career has given me—to educate, to advocate, and to inspire. Whether it’s through my work, my writing on RD on the Run, or the connections I’ve made with fellow dietitians and clients, I’m proud to be part of a profession that truly makes a difference.
To my fellow RDs and RDNs—thank you for all that you do! Whether you’re just starting your journey or have been in the field for decades, know that your work matters. Happy Registered Dietitian Nutritionist Day!

Happy RDN Day, Megan!!!
