Dr. Alana John
Founder & Medical Director
Expertise Meets Personalization
Dr. Alana John is a triple board-certified physician in Internal Medicine, Pulmonary Medicine, and Critical Care Medicine, with advanced training in functional medicine. In the ICU, where multi-organ failure and high-stakes decision-making are the norm, she developed the ability to quickly identify patterns across complex systems. She now applies these skills proactively in her wellness approach.
Before medicine, Dr. John worked as a science teacher, a role that honed her natural ability to explain complex concepts clearly, an approach she continues with patients today. She earned her medical degree through the Global Scholars Program, training across Grenada, the UK, and the US, before completing specialty training in Internal Medicine, Pulmonary Medicine, and Critical Care Medicine. Her career has spanned diverse healthcare settings across the United States, from major academic centers to rural programs, including time-serving Amish communities, an experience that strengthened her respect for individualized, patient-centered care.
Her extensive education and clinical experience allow her to view the body as an interconnected system, addressing root causes rather than symptoms alone. Dr. John focuses on delivering personalized, evidence-based care designed to optimize health, restore balance, and support long-term wellness.
