Board-certified in Gastroenterology
by American Board of Internal Medicine

Board-certified gastroenterologist-led longevity medicine for Miami, Palm Beach, Tampa, and high-performing Florida families. Virtual care, clinical precision, total discretion.

Who We Serve

Physician-led longevity medicine for Florida's most demanding principals, executives, and multi-generational families. Whether you’re based in Miami, Palm Beach, or anywhere across the state, your care is fully managed and seamlessly integrated into your schedule.

I. The Palm Beach & Jupiter Principal

Palm Beach · Jupiter Island · North Palm Beach · Manalapan · Palm Beach Gardens

You manage generational wealth from one of the most concentrated UHNW corridors in the United States. Whether your primary estate is on Palm Beach Island itself, the ultra-private reaches of Jupiter Island, or the established communities of North Palm Beach and Manalapan, your financial infrastructure is flawlessly managed. Your biological infrastructure is not. LongevIQ GI provides the clinical depth your wealth management already demands — advanced gut microbiome sequencing, epigenetic age analysis, comprehensive cardiometabolic profiling — delivered by a board-certified gastroenterologist operating entirely outside the insurance system. A Health Fiduciary, unconflicted and focused solely on your biological trajectory.

II. The Miami Financial & International Principal

Brickell · Coconut Grove · Coral Gables · Fisher Island · Pinecrest

You operate at the intersection of international capital and South Florida’s financial architecture. From the executive corridors of Brickell to the established residential enclaves of Coconut Grove and Coral Gables, and the ultra-private communities of Fisher Island and Pinecrest, your professional and personal life demands a clinical partner who understands discretion as a baseline requirement. LongevIQ GI serves Miami’s financial and international principals with the same rigor applied to any complex asset — precision diagnostics, longitudinal biological oversight, and a physician whose clinical loyalty is unconflicted. Whether your family capital is domestic or multi-jurisdictional, your biological capital deserves the same standard of stewardship.

III. The Tampa Bay & Gulf Coast Executive

South Tampa · Davis Islands · Hyde Park · Sarasota · Longboat Key · Bird Key

Tampa has become one of the most significant wealth migration destinations in the United States. Financial services firms relocating from New York and Chicago, healthcare system executives from Tampa General and Moffitt Cancer Center, and founders who have chosen South Tampa and Davis Islands as their operational base represent a distinct and growing UHNW cohort. South along the Gulf Coast, Sarasota’s established estate community — Longboat Key, Bird Key, and the Sarasota arts and philanthropy corridor — represents a quieter, deeply rooted wealth profile with the same demand for clinical precision. LongevIQ GI serves both communities with a fully virtual, physician-led model built for principals who will not compromise on clinical rigor.

IV. The Naples & Southwest Florida Estate Principal

Naples · Port Royal · Aqualane Shores · Marco Island · Bonita Springs · Estero

Naples represents one of the highest per-capita wealth concentrations in the United States. Port Royal and Aqualane Shores are among the most exclusive residential addresses in Florida — home to Midwest and Northeast principals who relocated to Southwest Florida seeking privacy, climate, and a community that understands long-term asset stewardship. Many clients in this corridor are in their fifties and sixties, actively managing a thirty-year biological horizon with the same discipline applied to their estate plans. LongevIQ GI is designed precisely for this profile — a physician-led longevity practice that treats healthspan as a capital investment, built to sustain the high-activity lifestyle of Port Royal and Aqualane Shores across the next three decades. Clinical precision without the volume and noise of conventional medicine, operating on your schedule, in your environment, with complete discretion.

V. The Multi-Residence Florida Principal

Florida primary · Pennsylvania · Texas · Northeast corridor

Florida is your primary residence, but your life does not stay in one state. Whether you maintain a second home in Pennsylvania’s Main Line, a presence in Texas for business, or continue active engagement with the Northeast institutions and relationships that built your career, your health cannot be anchored to a single clinic. LongevIQ GI is fully virtual and licensed across Florida, Pennsylvania, and Texas. Your diagnostic baseline is established once. Your protocol adapts continuously. Your physician — Dr. Banerjee — remains consistent regardless of which residence you are in or which timezone your schedule has placed you. This is what physician-led longevity care looks like when it is built for the way your life actually operates.

Precision Medicine Miami — The Gut Is Where Biological Age Is Set

Standard longevity protocols ignore the gut — the primary regulator of systemic inflammation and biological age. Circulating microbial metabolites, intestinal barrier integrity, and microbiome-derived SCFA production are upstream variables that determine how every downstream intervention performs. CoQ10 and NAD+ supplementation demonstrate measurably reduced efficacy when gut dysbiosis persists. Epigenetic clocks accelerate when barrier function is compromised. This is the gap that no generalist longevity platform addresses.

At LongevIQ GI, every protocol begins with the biology that the rest of the field omits. Led by a board-certified gastroenterologist with deep microbiome expertise and over 15 years of clinical and research experience, we build longevity strategies from the gut up — because that is where biological age is actually set. Dr. Banerjee operates entirely outside the insurance system — no volume incentives, no conflicted referral networks. Clinical loyalty to one principal: you.

Why Early Detection Changes Everything

Breakthrough diagnostics uncover risks years before symptoms appear — giving you the advantage of time.

Deep Phenotyping

Advanced gut microbiome sequencing, epigenetic age analysis, comprehensive cardiometabolic profiling, toxic load assessment, and VO₂ max evaluation. We establish your complete biological baseline — not a snapshot, a full systems map.

Strategic Protocol

A personalized longevity roadmap built from your diagnostic data. Every intervention is evidence-anchored. Supplements and nutraceuticals are deployed only where clinical evidence is unambiguous. The protocol is yours — designed around how your life is actually structured.

03

Active Stewardship

Quarterly physician-led optimization and refinement. Your biology changes; your protocol adapts. Ongoing direct access to Dr. Banerjee — not a care coordinator, not a patient portal. The physician.

I am fortunate to have had Dr. Banerjee as my personal physician for several years. From the start, he has been genuinely engaged with his patients, listening carefully and explaining tests and recommendations in a calm, intelligent, and reassuring way. I have recommended him to family and friends as an outstanding physician who truly cares. It has often occurred to me that he would make a wonderful medical professor, teaching young doctors to care for both the mind and body with intelligence and compassion.
Maria G.
“Dr. Banerjee is a very attentive and thoughtful practitioner. While under his care, he placed special emphasis on explaining treatments, fully answered all my questions, and ensured that my concerns received his complete attention. As a patient, this made me feel respected and confident that I received a world-class level of care.”
