Background

Hola and Welcome!

Mia here, a Registered Dietitian helping people connect with nutrition in a way that supports their health, culture, and lifestyle. But more importantly, I’m someone who will listen and walk with you on your wellness journey. 

Nutrition is never one-size-fits-all. I am here to understand your nutrition story—your routines, challenges, and traditions—and together, we build a plan that feels realistic, respectful, and personal. 

Whether you’re managing a condition, looking for more energy, or want to feel better in your body, I’m here to support you every step of the way. 

Our sessions are a judgment-free zone where education is empowering, accountability is compassionate, and progress—big or small—is always celebrated!

This is your journey, and I’m honored to be part of it. Let’s create something meaningful, together!

Approach

As a bilingual (EN-SP) RD, I provide personalized, culturally respectful care with empathy at the core. I support each client's journey with a combination of education and real-life strategies that honor their traditions and goals. I strive to make each session engaging and supportive, while making accountability empowering and not overwhelming.
