Longevity advice was splitting into two camps — cautious academic medicine that rarely reached patients, and a wellness industry moving faster than its evidence. Keside was built to sit in neither camp. What follows is the method that came out of that: Global Longevity Intelligence.
Keside Med Group started in Boston in 2018 as a single advisory practice: one internist, a handful of clients, and a conviction that the research on healthy aging was more actionable than most people were getting the benefit of.
The practice grew by referral, not marketing. As it grew, it added physicians and researchers with backgrounds outside the United States — not for variety's sake, but because the most useful clinical practice patterns on longevity aren't concentrated in any one country. That became the model: read broadly, personalize narrowly.
We track research and clinical practice across multiple health systems, not one journal or one country.
Global evidence is the input. Your plan is the output — and it looks different for everyone.
Where the evidence is thin, we say so, rather than filling the gap with confidence.
An advisory relationship, not a one-time report. Plans get reviewed and adjusted, not filed away.
Founded in Boston as a single advisory practice.
First formal research partnerships outside North America, in Northern Europe — the start of what's now the Research Network.
Launched the Family Office Health Program for multi-generational clients.
Expanded the advisory team and formalized the Global Longevity Intelligence method below.
Rather than working from a single country's guidelines, our research team reviews clinical literature, public health guidance, and practice patterns from health systems across North America, Northern Europe, and East Asia — three regions with meaningfully different approaches to preventive and longevity-oriented care.
This isn't about chasing exotic protocols. It's about noticing where independent health systems agree, which is usually a better signal than any single study, and where they genuinely differ, which is usually a sign the evidence is still unsettled. Both findings shape the plans we build.
A comprehensive assessment — laboratory biomarkers, functional testing, and a detailed clinical and family history — establishes where you actually stand, not where a population average stands.
We also spend real time on goals: what you're optimizing for, what trade-offs you're willing to make, and what a good outcome looks like five, ten, and thirty years out. Two clients with near-identical lab results can leave with different plans because their answers here were different.
Your plan sets out what to change, what to monitor, and — critically — why, in plain language, with the evidence behind each recommendation made explicit rather than implied.
We deliberately avoid handing clients a list of supplements with no explanation. If a recommendation doesn't have a defensible reason attached to it, it doesn't go in the plan.
Quarterly reviews check your plan against new results, a changed life circumstance, or research that has moved since the last visit. Care coordination means your advisory team, not you, chases down specialists and records.
This is the part most "longevity" offerings skip. A single assessment is a snapshot; the value compounds in the years of adjustment that follow it.
