We fully believe...
Everyone deserves quality, non-discriminatory healthcare.
Body trust is not a fantasy.
Peace with food and our bodies is attainable and leads to freedom from diet culture.
Everyone can change.
In working with our bodies, not against them.
Eating and movement are meant to be enjoyable!
Self-compassion and acceptance are essential parts of healing our relationship with food and our body.
In evidence-based practice and research that is free of weight bias.

Meet Holly
Executive Assistant / Client care coordinator
Holly graduated from Belmont University with a degree in Motion Pictures. She then went on to work as an associate producer for a media and entertainment company in Nashville. However, after facing significant gut issues of her own, she took a step back from the fast-paced film industry to focus on nutrition and healing. Now, she finds fulfillment in working to help clients discover their own healing at Radiant Nutrition. Her role includes onboarding new clients, creating social media content, marketing, and writing on the blog! Holly understands how difficult it can be to struggle with your health and is here to answer any of your questions with compassion and care!
In her free time, Holly likes to cook, draw, and dream of one day owning a farm with lots of animals. She takes pride in being a Disney adult and you can usually find her and her husband at EPCOT in the evenings. Her dog, Tecova, is a ball of energy and a constant source of joy and occasional destruction.
I have struggled with my eating patterns and self-image my entire life. One day last year, I decided to finally take a step toward getting better, and reached out to radiant nutrition. Devon not only helped me figure out my problem, but did it with compassion and kindness. She listens to every word I say and makes me feel like she understands me. After feeling lost for so long, Devon helped me take the right steps toward healing my eating disorder which led to me regaining my confidence and finally feeling some sense of normalcy. Where I am now compared to this time last year is a world of a difference, and I don’t plan on going back to my previous habits. I am so thankful for Devon’s patience and compassion. She has become a major part of my story and has become a good friend in the process. I honestly don’t know where I’d be without her.
- Katie T.
I have struggled with disordered eating and body image most of my adult life. When my doctor referred me to Devon, I had no idea the impact it would have on me. Devon has taught me sustainable eating habits that have changed my life for the better. I’ve learned how to listen to my body and make better choices that still leave me satisfied. I have PCOS and she has helped me understand so much about insulin resistance and how it affects my body. Devon has also worked with me on body image, which I have always struggled with. She is positive, compassionate, patient, and encouraging. I am so thankful to Devon for teaching me better ways to manage my health, and for helping me reshape the way I think about myself.
