Eat well. Live your best.

Meet the founder

Good nutrition should help you live more fully—not make your life revolve around food.

I’m a licensed dietitian, Certified Nutrition Specialist®, Certified Personal Trainer, nutrition educator, and published researcher—and the founder of Core Nutrition.

But more importantly, I’m someone who believes nutrition guidance should feel thoughtful, practical, personal, and grounded in science.

It’s a lot.

There is more nutrition information available today than ever before, yet people are often more confused about what to eat than ever. Protein. Carbs. Seed oils. Supplements. Blood sugar. Fasting. Gut health. Hormones. “Clean” ingredients. Foods you supposedly must eat and foods you’re suddenly supposed to fear.

My role is to help you cut through that noise, understand what actually matters for your health, and build an approach to nutrition that feels both effective and realistic. Because eating well should support your life. Not consume it.

The path here

My path to Core Nutrition wasn’t a straight line—and I’m grateful for that.

Before nutrition became my profession, education was already a major part of who I was. My career began in teaching and later expanded into professional learning and higher education—experiences that taught me something I still believe deeply today: information becomes powerful when someone knows how to make it understandable.

What began as an interest in health grew into advanced graduate study, clinical training, research, board certification, and eventually the creation of Core Nutrition.

I completed rigorous graduate-level nutrition education and extensive supervised clinical experience working with adults across a wide range of nutrition and wellness concerns. Along the way, I also had the opportunity to contribute to published research—an experience that strengthened my appreciation for both the science behind nutrition and the responsibility involved in translating that science accurately.

Nutrition should be personal

Science gives us direction. Your individual needs determine the path.

Two people can have the same goal and need very different strategies to reach it. Your health history matters. Your lifestyle matters. Your preferences matter. Your relationship with food matters. Your schedule, family, stress, sleep, physical activity, environment, priorities, and season of life all matter.

That’s why I don’t believe in simply handing someone a generic plan and sending them on their way. Instead, I take time to understand the bigger picture—where you are now, what may be influencing your health, what matters most to you, and what changes are both meaningful and realistic enough to sustain.

Look deeper. Build stronger foundations.

The Core Approach

We may look beyond the obvious question of “What are you eating?” and explore the broader factors that could be affecting how you feel and function. The goal isn’t to chase every possible explanation or make wellness unnecessarily complicated—it is to ask thoughtful questions and create a strategy with purpose behind it.

  • Evidence-Based

    Recommendations should be supported by credible nutrition science—not fear, trends, or viral wellness claims.

  • Individualized

    Your plan should reflect your body, your life, your goals, and your preferences.

  • Food-First

    Whenever appropriate, we begin with food and foundational habits before adding complexity.

  • Root-Cause Oriented

    Rather than focusing exclusively on a symptom or number, we consider the larger picture and factors that may be contributing to it.

  • Practical

    Knowing what to do isn’t particularly useful if it doesn’t work in your actual life.

  • Sustainable

    There are no prizes for following the “perfect” diet for three weeks. I’m much more interested in helping you build habits you can carry with you for years.

Why Core?

Core reflects looking beyond the surface.

The word Core reflects the foundation of the way I think about health. Nutrition is one of the core elements that supports how we feel, function, move, perform, recover, and age.

Instead of simply asking what you should eat, we can ask why a particular nutrition strategy makes sense for you. Instead of chasing quick fixes, we can strengthen the habits and foundations that support health over time. Instead of making decisions based on the latest wellness trend, we can return to what matters most: good science, thoughtful care, and the individual person.

And that is what inspired the Core Nutrition promise: Eat well. Live your best. Because nutrition isn’t the final destination. Living well is.
