People Who Care About Your Health as Much as You Do

Founder & Owner · Registered Dietitian Nutritionist

I'm Janna, a Registered Dietitian Nutritionist, founder of Radiant Nutrition, and someone who truly understands the struggle of trying to "get it right" when it comes to health and nutrition. With over 20 years of experience, I've built this practice on the belief that nutrition should be realistic, sustainable, and empowering. I specialize in weight loss management, adult and family nutrition, and corporate wellness, combining evidence-based strategies with a compassionate, no-judgment approach. I hold advanced certifications in Adult and Pediatric Weight Management through the Academy of Nutrition & Dietetics and have been honored as a Best of Denton County winner for the past two years, as well as a DFW Mom-Approved provider.

Hi, I'm Sabrina! I'm a Registered Dietitian Nutritionist with a heart for helping people feel their best — without the stress, guilt, or overwhelm that can sometimes come with nutrition. I believe in real-life, realistic approaches that actually fit your lifestyle, whether you're juggling a busy schedule, trying to make small but meaningful changes, or looking to revamp your nutrition completely. My clients describe me as positive, encouraging, and practical — always helping them find ways to improve their nutrition without feeling overwhelmed.

RDN, LD
Registered Dietitian Nutritionist

I'm Jenny, a Registered Dietitian Nutritionist with a heart for helping people feel heard, understood, and empowered in their health journey. My love for nutrition started in high school, and that passion led me to UT Southwestern where I earned my Bachelor of Science in Clinical Nutrition, and then to Parkland's Neonatal ICU. As a mom of three teenagers (two student-athletes), I know the struggle of getting healthy meals on the table. My clients say I fit nutrition into life — not the other way around — with small, sustainable changes that create lasting results.
