Concierge Longevity Physician in Pennsylvania
Board-certified gastroenterologist-led longevity medicine for Philadelphia, the Main Line, Pittsburgh, and high-performing Pennsylvania families. Virtual care, clinical precision, total discretion.
Who We Serve
Physician-led longevity medicine for Pennsylvania's most demanding principals, executives, and multi-generational families. Whether you’re based in Philadelphia, Pittsburgh, or anywhere across the state, your care is fully managed and seamlessly integrated into your schedule.
I. The Institutional Founder & Main Line Principal
You manage a complex enterprise — a family office, a multi-generational legacy, or a global operation — from a primary residence in Villanova, Haverford, Gladwyne, or Bryn Mawr. Your financial capital is rigorously stewarded. Your health is the primary engine of that legacy and deserves the same depth of oversight. LongevIQ GI provides a clinical partnership built on advanced diagnostics, longitudinal accountability, and a physician who functions as a Health Fiduciary — unconflicted, proactive, and entirely on your terms.
II. The Center City Power Architect
You are a Philadelphia executive, private equity partner, or senior operator who values time above all else. You require a virtual-first, data-intensive clinical model that integrates without friction into a high-stakes schedule. From the historic residences of Society Hill to the premier corridors of Rittenhouse Square and Fitler Square, LongevIQ GI delivers precision longevity stewardship directly to your environment — no clinic visits, no waiting rooms, no compromised discretion.
III. The Western Pennsylvania Visionary
For the principals of Pittsburgh’s industrial, technology, and healthcare sectors who expect a peer-to-peer clinical relationship with a board-certified specialist. Whether you reside in the ultra-private boundaries of Sewickley Heights and Edgeworth, or in the established corridors of Fox Chapel and Shadyside, LongevIQ GI delivers the same clinical precision available to any client — entirely virtually, on your schedule, with complete discretion.
IV. The Legacy Estate & Tech Corridor Leader
For the discerning family principal who views healthspan extension as a long-term capital investment. Designed for residents of the Bucks County estate tier — New Hope, Solebury, Washington Crossing — as well as the pharmaceutical and technology leaders of Malvern, Devon, and Berwyn. You demand PubMed-indexed clinical rigor and a physician who operates entirely outside the insurance system. That is what a Health Fiduciary delivers.
V. The Multi-Residence Client
Your life moves between a primary residence in Pennsylvania, a second home in Florida, and a professional schedule that makes traditional clinic relationships impractical. LongevIQ GI is fully virtual and licensed across Pennsylvania, Florida, and Texas. Whether you are in Philadelphia, Palm Beach, or Houston, your protocol travels with you — and your physician remains consistent.
Precision Medicine Philadelphia — 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.

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

The Process
We’ve designed a streamlined, white-glove experience that delivers high-impact insights and measurable outcomes — entirely virtually
