Island Lifestyle Medicine was founded on a simple belief: primary care should be personal, accessible, and focused on long-term health. As a locally owned practice in Fernandina Beach, we are committed to building meaningful relationships with our patients and delivering care without the limitations of traditional insurance-based systems.
Led by Dr. Diana Twiggs, our practice blends decades of experience in family medicine with a modern, evidence-based approach to lifestyle medicine — helping patients prevent, manage, and even reverse chronic disease.
Dr. Twiggs is board certified in Family Medicine and Lifestyle Medicine. This dual certification allows her to combine comprehensive primary care with advanced training in evidence-based lifestyle interventions. The goal is to implement lifestyle changes first, and use medications when needed.
Throughout her career, Dr. Twiggs has been recognized for her dedication to patient care, clinical excellence, and service to the community.
