My Story

I didn’t always trust my body.

For a long time, I approached health through control. I tried to outthink hunger, follow the right rules, and optimize my way into feeling better. From the outside, it looked disciplined. Internally, it felt like I was constantly negotiating with myself.

Over time, I realized something simple but hard to accept:
you can’t build a healthy relationship with your body through control alone.

I grew up as a competitive Irish dancer, where precision, discipline, and pushing through discomfort were the standard. That environment, along with early exposure to healthcare, pulled me toward clinical nutrition. I went on to become a Registered Dietitian and Certified Personal Trainer.

My clinical training started during COVID in a level-one trauma center. It was a crash course in how healthcare actually functions. I saw how much health is shaped by more than physiology alone. Behavior, environment, stress, access, and context all matter. Often more than we acknowledge.

Around that same time, I was navigating my own health challenges, including an eating disorder. Recovery forced me to rethink everything I thought I knew. Not just about food, but about control, identity, and what it actually means to take care of yourself.

After working in acute care, I left with a clear and overwhelming conviction:

We cannot rely on reactive care to build real health.

I saw firsthand how much effort, expertise, and resources go into managing illness once it has already taken hold. And while that care is essential, it also made something undeniable to me. By the time most people enter the system, we are already behind.

It became clear that if I wanted to meaningfully impact health, I couldn’t just work within that model. I needed to be part of building something earlier, more proactive, and more human.

That realization didn’t lead me straight into private practice.

If anything, it pulled me off the expected path entirely.

I spent time doing door-to-door sales, which, unexpectedly, ended up shaping my perspective more than I anticipated. I had conversations every day with people who looked like they had everything together, yet felt confused, exhausted, or stuck when it came to their health.

That experience gave me space to travel, step outside of my own routines, and connect with people in a different way. It also made something very clear: the need for real, honest, full-person support is much bigger than most systems are built to handle.

Today, my work is centered on helping people step out of extremes and into something more steady.

I combine clinical nutrition, behavior change, and nervous system awareness to help you build habits that are actually doable. Not perfect, not rigid, but consistent enough to create real change.

Less noise. More clarity.
Less starting over. More follow-through.

Because health isn’t something you force.
It’s something you build.

If you’ve been doing everything “right” but still don’t feel right, you’re not the problem.
There’s likely a mismatch between the approach you’ve been given and what your body actually needs.

About Me

Outside of my work, I’m happiest when I’m creating or exploring. I grew up as both an elite-level Irish dancer and an art kid– two passions that taught me discipline, creativity, and how to express myself through movement and color.

I love traveling anywhere and everywhere and making things with my hands: sewing, painting, working with clay, and collaging.

I believe healthcare is a universal right, and I’m deeply passionate about breaking down barriers that keep people from accessing the care, education, and support they deserve.

I love cooking (especially for people I care about), and some of my favorite evenings are spent making dinner and listening to Tiny Desk concerts with my girlfriends. Those moments remind me that food connects us far beyond nutrition.

Movement has always been a grounding force for me: I love hiking, running (primarily) half marathons, golfing, lifting weights, functional movement, a night out dancing, yoga, and skiing.

Philosophy

What “Eighty Twenty” Really Means

At its core, Eighty Twenty redefines health as something that supports life, not overshadows it. It’s a philosophy that values progress over perfection and reminds us that consistency matters more than control.

An eighty twenty approach means that most of the time, you make health-informed, science-based choices that support your energy, focus, and longevity. And sometimes, you simply enjoy what brings you joy. We allow space for both structure and spontaneity. Extremes rarely serve us, no matter how perfectly they’re packaged. In nutrition, as in life, real change lies in the middle: habits that are flexible, enduring, and quietly powerful.

Over time, health shouldn’t feel like another task to manage. It should become an integrated foundation that blends into the background of your life. A restructuring, not another restriction. When nourishment, movement, and rest become natural extensions of how we live, they stop consuming our energy and begin restoring it– freeing us to invest more deeply in the relationships, goals, and experiences that give life meaning.

At eighty twenty, this philosophy guides every program, partnership, and conversation. The goal isn’t perfection. It’s integration. So you can build a relationship with food, movement, and yourself that’s informed, sustainable, and quietly transformative.
