Our approach

Founded on a simple frustration.

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.

Where it started

One advisor, then a small group of them.

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.

What doesn't change

Four commitments, independent of whatever's trending.

Read broadly

We track research and clinical practice across multiple health systems, not one journal or one country.

Personalize narrowly

Global evidence is the input. Your plan is the output — and it looks different for everyone.

Say what we don't know

Where the evidence is thin, we say so, rather than filling the gap with confidence.

Stay in the room

An advisory relationship, not a one-time report. Plans get reviewed and adjusted, not filed away.

Since 2018

A short, honest timeline.

2018

Founded in Boston as a single advisory practice.

2020

First formal research partnerships outside North America, in Northern Europe — the start of what's now the Research Network.

2022

Launched the Family Office Health Program for multi-generational clients.

2025

Expanded the advisory team and formalized the Global Longevity Intelligence method below.

01 — Global synthesis

We start wider than most advisory practices do.

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.

02 — Individual assessment

Then we narrow back down to one person.

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.

03 — Personalized protocol

Synthesis and assessment become one document.

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.

04 — Ongoing advisory

The plan is a draft, not a verdict.

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.
