Meet Dietitian Group: Registered Dietitians Who Actually Get to Know You
Food doesn’t have to feel like a test you keep failing. At Dietitian Group, our registered dietitian nutritionists help you manage diabetes, PCOS, and blood sugar without giving up the foods you love or following another rigid plan.
Why I Started Dietitian Group
Early in my career, I worked at a weight loss clinic that ran a very restrictive program. I watched people follow the rules perfectly, lose weight, and then feel like failures when life got in the way and the weight came back. That wasn’t the kind of dietitian I wanted to be.
From there I worked in hospital inpatient care, opened an outpatient nutrition center, and joined a telehealth nutrition company, where I worked my way up to clinical director and led a team of 23 dietitians. Over and over, the clients who made lasting changes were the ones who felt understood, not judged.
I started Dietitian Group in 2022 to make that kind of care easier to get: dietitians who take the time to know you, nutrition advice that fits your real life, and visits that work with your insurance. I also teach insurance billing and coding to dietetic interns at Lipscomb University, because I want more dietitians to be able to build practices like this one.

Our Approach: The THRIVE Method™
Every Dietitian Group dietitian uses the THRIVE Method™, our non-diet, weight-inclusive way of building habits that last. Instead of handing you a meal plan and wishing you luck, we start with your life: your schedule, your favorite foods, your lab results, and what has and hasn’t worked before.
- T: Truly Personalized. Your plan is built around your life, not a template.
- H: History-Informed Approach. We look at what you’ve tried before and what got in the way.
- R: Real Results, Not Shortcuts. Changes you can keep, measured in how you feel and what your labs show.
- I: Inclusive Food Philosophy. Every food can fit, including the ones you love.
- V: Varying With Life’s Seasons. Your plan adjusts when your schedule, health, or goals change.
- E: Empowerment Through Progress. Each small win builds confidence for the next one.
If you have a weight goal, we’re happy to work on it with you, through habits you can keep rather than rules you’ll eventually break.
Who We Help
Our clients range from busy professionals to people referred by their doctor. Most come to us for one of these reasons:
- Diabetes and prediabetes. Type 1, type 2, gestational, and prediabetes. Steadier blood sugar, a better A1C, and meals that don’t feel like math homework.
- PCOS. Eating to support your hormones, energy, cycles, and fertility goals, without cutting out entire food groups.
- GLP-1 medications. Getting enough protein, managing side effects, and building habits that hold up if you ever come off the medication.
- Disordered eating and your relationship with food. If you’ve spent years dieting, feel guilty after eating, or don’t know what to eat anymore, we’ll help you make peace with food.
