Adena Marie Hicks, MD, MPH
I approach patient care as both a clinician and a physician-advocate, grounded in the belief that every person deserves to feel seen, heard, and equipped in their health journey. I enjoy the diagnostic process and bring patients into it, using clear communication, humor, and trust-building to create a space where they feel comfortable asking questions and engaging in their care.
Clinically, I integrate efficient, evidence-based medicine with a lifestyle and prevention-focused approach that meets patients where they are. Whether I’m addressing an urgent concern or supporting chronic disease management, I consider the full context of a patient’s life—access, affordability, stress, movement, and nutrition—because sustainable health doesn’t happen in isolation. I aim to not only treat what’s in front of me, but to equip patients with the tools and understanding to move forward with confidence, bridging immediate care with long-term well-being.
Dr. Hicks provides medical services in our new direct primary care Midtown office.
