Eat well. Live your best.

Eat well. Live your best.

Personalized nutrition. Rooted in science. Built around you.

At Core Nutrition, nutrition isn’t about restriction, perfection, or another one-size-fits-all plan. It’s about understanding your unique needs, getting to the core of what may be standing between you and your goals, and creating realistic strategies that support your health for the long term.

Through personalized, evidence-based nutrition counseling, I help you build a stronger foundation for better health—one sustainable change at a time.

Virtual nutrition counseling and medical nutrition therapy are available where permitted by applicable state law.

Nutrition that gets to the Core.

There is no universal formula for better health.

Your nutrition needs are shaped by your lifestyle, health history, goals, preferences, environment, activity, and the many factors that make you uniquely you. That’s why Core Nutrition takes a personalized approach.

Rather than simply telling you what to eat, we look deeper—at your current habits, nutrition patterns, lifestyle, movement, goals, and the bigger picture of your health—to develop practical strategies you can actually use in real life.

Because good nutrition shouldn’t make your life harder. It should make living well easier.

Discover How I Can Help

Less noise. More clarity.

Nutrition advice is everywhere.

And somehow, eating well has never felt more confusing. At Core Nutrition, we filter out the noise and focus on what the evidence—and your individual needs—actually support.

01

Evidence-Based

Recommendations are grounded in current nutrition science rather than wellness trends, fear-based messaging, or social media hype.

02

Personalized

Your strategy is built around your goals, lifestyle, preferences, health history, and real life—not someone else’s meal plan.

03

Root-Cause Focused

Instead of focusing only on symptoms or numbers, we look at the bigger picture and nutrition and lifestyle factors that may be contributing.

04

Food-First

Whenever appropriate, we begin with realistic ways to improve what you’re already eating before making nutrition unnecessarily complicated.

05

Sustainable

The best nutrition plan isn’t the most perfect one. It’s the one you can actually live with.

06

Whole-Person

Physical activity, sleep, stress, routines, environment, and behavior all influence health and may become part of your personalized strategy.

How we work together

We talk through your goals, health history, routines, and what you want support with.

2. Build Your Plan

3. Put It Into Practice

Dietitian. Nutrition scientist. Educator. And a firm believer that healthy eating should still feel like living.

I created Core Nutrition because people deserve nutrition guidance that feels both credible and human. My work combines advanced nutrition education, clinical training, published research, and a genuine love of teaching to help translate complicated nutrition science into strategies that make sense in everyday life.

As a licensed dietitian, Certified Nutrition Specialist®, and Certified Personal Trainer, I take an integrated approach to nutrition and wellness—looking beyond food alone to consider the many factors that influence how we feel and function.

Why Core Nutrition?

Your health deserves a strong foundation.

The name Core Nutrition represents more than nutrition counseling. Nutrition is one of the core elements that supports how we feel, move, function, perform, and age. “Core” also reflects the philosophy behind my work—looking beyond the surface, asking better questions, and getting closer to the factors that may be influencing your health.

The Core Nutrition logo reflects those same ideas: growth, vitality, nourishment, and the connection between the choices we make today and the life we want to live tomorrow.

Good nutrition guidance begins with good science. My background includes graduate-level nutrition education, extensive supervised clinical experience, professional certification, and published academic research.

Research

Better information helps you make better decisions.

Evidence-based nutrition, translated for real life.

You shouldn’t have to become a nutrition scientist just to figure out what to eat. The Core Nutrition Learn library breaks down nutrition research, trending wellness topics, food questions, supplements, recipes, family nutrition, metabolic health, and more—without the hype.
