Functional Medicine Florida is a root-cause medicine practice in Sarasota, Florida led by Dr. W. Frederic Harvey, MD — the longest-standing functional medicine physician in Sarasota and one of the most credentialed integrative practitioners in the state. Dr. Harvey is quadruple board certified in Internal Medicine, Geriatric Medicine, Functional Medicine, and Holistic/Integrative Medicine, with over 30 years of clinical experience. The practice operates under a “disease reversal” philosophy rather than chronic illness management — a meaningful distinction for patients who have been told they simply need to manage their conditions indefinitely. The practice launched a fully virtual care model in late 2025 and now serves patients worldwide in addition to its Sarasota-based in-person practice. Dr. Harvey does not accept insurance or Medicare; the practice operates as a cash-pay model with detailed super bills provided for self-filing.

About the Physician

Dr. Harvey earned his medical degree from Jefferson University (Kimmel School of Medicine) and holds board certifications through the Institute for Functional Medicine (IFM), in addition to his conventional Internal Medicine and Geriatric Medicine credentials. He is the host of the Healthy Steps Radio Show on WMNF and has been featured on Close-Up Radio. His signature “Toxiflammation” framework — the toxic-inflammatory feedforward loop — drives his diagnostic and treatment approach, recognizing that most chronic disease stems from the accumulation of toxins and inflammation working in concert. The practice uses advanced laboratory partners including Genova Diagnostics, Doctor’s Data, Precision Point Diagnostics, Vibrant America, and ZRT Lab for functional testing not available through standard clinical labs.
