HI! I’M SOPHIA

Sophia Deahl is an integrative and functional medicine registered dietitian, educator, and speaker dedicated to addressing the root cause of health concerns through personalized nutrition and lifestyle interventions. She partners with clients in both 1:1 and group programs, guiding them every step of the way to optimize their physical and mental well-being, reclaim their health, and build sustainable habits for long-term vitality.

By blending functional, holistic, and integrative medicine, Sophia focuses on key pillars of health—including nutrition, gut health, movement, sleep, stress resilience, detoxification, and mindfulness—to support the body and mind as a whole. Her approach is deeply personalized, helping clients understand their unique health needs, develop tailored strategies, and foster a balanced mindset that transforms their relationship with food and self.

Beyond working with individuals, Sophia is also an educator and mentor to fellow practitioners, sharing her expertise to help them refine their skills and deepen their impact. She speaks at events, conferences, and workshops, bringing science-backed insights on longevity, lifestyle medicine, and functional nutrition to a broader audience.

Her mission is to empower people to take control of their health, find balance, and build lasting habits that align with their purpose and well-being. Through precision medicine (advanced lab testing & wearable technology) and a root-cause approach, she equips her clients with the knowledge and tools they need to thrive—physically, mentally, and emotionally.
