About
Mia Sierra, MBA, RD, is a bilingual Registered Dietitian who helps people feel better through simple, personalized nutrition. Her goal is to make healthy eating approachable, practical, and tailored to your unique lifestyle, culture, and health goals. Mia offers care that is respectful, supportive, and grounded in science—whether you're managing a health condition, working toward a wellness goal, or simply trying to eat better without feeling overwhelmed. Fluent in English and Spanish, she creates a welcoming environment for individuals and families from diverse backgrounds.
Mia believes nutrition should work for you—not the other way around. Her approach is gentle, personalized, and realistic. Rather than giving one-size-fits-all advice, she listens to your story, understands your needs, and works with you to create a plan that fits your life—not someone else’s idea of it. Whether you’re looking to manage a condition, feel more energized, or improve your relationship with food, Mia employs a supportive and non-judgmental approach that encourages small, meaningful changes. She blends science with compassion, always respecting cultural food traditions and personal preferences.
Your first visit is an opportunity to share your health story and discuss what matters most to you. Mia will take the time to understand your eating habits, medical history, lifestyle, and goals—whether that’s lowering blood sugar, reducing inflammation, improving digestion, or simply feeling better day-to-day. You’ll leave with practical next steps and a care plan that’s doable, flexible, and tailored just for you. The session lasts approximately one hour and can be conducted virtually or in person.
