Hi, I’m Sophia Deahl, MS, RDN

I am a functional medicine trained registered dietitian and mental health coach with a background in psychology and neuroscience research. I believe in a whole-person integrative approach to health and wellness.

I am passionate about helping individuals reclaim their health and understand the root-cause of their symptoms.

I help people understand the deeper why behind their mental health struggles and guide them with simple, science-backed strategies to feel clearer, calmer, and more like themselves again.

Holistic Nutrition & Health Coaching for Mental Health

Most of us are taught that mental health lives solely in the brain.

But your body & brain are connected, which means your mental health is affected by your physical health and vice versa. Your mental health is affected by what you eat, how you sleep, your blood sugar, your inflammation levels, and even your gut health.

And when you learn how to work with your body, your mind can finally feel at ease.

ABOUT ME

I’m a functional medicine-trained dietitian with a background in psychology, neuroscience, and longevity. I hold a Master of Science in Nutrition, Healthspan, and Longevity from the University of Southern California, and have completed training through the Institute for Functional Medicine. My background also includes a BA in Psychology and Sociology, along with 3 years of experience in a neuroscience research lab—giving me a holistic and science-rooted lens on mental health care.

I believe science should be accessible, healing should be personalized, and no one should have to navigate their mental health alone.

Whether you’re here as a patient, a fellow professional, or simply exploring—welcome.

You’re in the right place.
