Telemedicine appointments are available for patients across Florida, including the Tampa Bay Area, South Palm Beach, and North Broward.
Functional medicine is a systems biology-based approach to healthcare that identifies the root causes of disease rather than treating symptoms in isolation. The word "causes" is intentionally plural — an important principle of functional medicine is that the same illness can have different causes in different people. A thyroid condition in one patient may be driven by autoimmunity; in another, by chronic stress or nutritional deficiency. Treating both identically is the weakness of conventional medicine that functional medicine addresses.
Dr. Rubin pairs this root-cause philosophy with a patient-centric model, meaning your treatment plan is built around your specific medical history, lab results, lifestyle, and goals — not a protocol designed for the average patient.
Conventional medicine excels at acute care and crisis management. Functional medicine is designed for the patients conventional medicine underserves: people with chronic conditions, unresolved symptoms, or a sense that something is wrong that routine bloodwork hasn't explained.
Where a conventional visit might end with a prescription for a symptom, a functional medicine consultation starts with questions. What has your diet looked like over the past decade? What medications are you on, and could any of them be contributing to your symptoms? Do your symptoms follow a pattern? Does your family history suggest a genetic component? Dr. Rubin uses advanced diagnostic lab testing — available onsite at both clinics — to build a full picture before recommending any treatment.
All chronic conditions benefit from a functional medicine evaluation, but the approach is particularly effective for:
After your initial evaluation, Dr. Rubin builds a personalized plan that may draw from any of the following depending on your specific findings:
No two plans are the same. Dr. Rubin treats each patient as a unique clinical case, not a set of symptoms to be matched to a standard protocol.
Dr. Rubin is ABIM Board Certified in Internal Medicine and Geriatrics Medicine and an Advanced Fellow in the American Academy of Anti-Aging Medicine. He spent the first 25 years of his career in internal and geriatric medicine, earning recognition from Castle Connolly Medical as one of the "Top Doctors" in South Florida for four consecutive years.
After completing a fellowship in anti-aging and regenerative medicine, he transitioned fully to functional medicine to better address the unmet needs of patients with chronic and complex conditions. Over the past 15 years, he has built a practice grounded in evidence-based care that takes the time conventional medicine rarely allows.
Free consultations are available at both clinics and via telemedicine for patients anywhere in Florida.
