The science of health optimization is advancing at a pace that most of us are only beginning to appreciate. What was cutting-edge five years ago is now baseline. What's emerging today will reshape what's possible in five more.
We are at the beginning of the most significant compounding curve in the history of human health.
Healthspanners is how we act on it.
One body system at a time. A clinical team building our protocols. Leading researchers and clinicians shaping them. And a community of peers invested in each other's outcomes.
Five founding cohorts. Twenty-five members. All five begin together in NYC.
The Methodology
The Protocol
Every Healthspanners protocol is built with clinical and research expertise in metabolic biology, cardiovascular science, sleep medicine, cognitive performance, and longevity therapeutics. Each protocol is designed so that our members are practicing what the science supports now, and positioned to act on what arrives next.
01
Pre-arrival
Leading-Edge Diagnostics
Each quarter begins with comprehensive diagnostics specific to the focus system, built on 200+ baseline biomarkers, genetic data, and every prior quarter's results. This is not a snapshot. It is a continuously deepening picture of each member's biology, designed with clinical and research expertise specific to each system.
02
Kickoff
Quarterly Dinner
The protocol launches at a quarterly gathering: an intimate dinner where a leading researcher or clinician presents the science, takes questions from a room of people who understand why it matters, and frames the work ahead. A chef designs every course around the quarter's theme. The function of each ingredient is part of the conversation. It is an evening at the frontier of health science, and it happens four times a year.
03
90 Days
Personalized Protocol
Over the following quarter, each member's dedicated Clinical Lead designs a protocol individualized to their biology. Medical Director oversight ensures rigor and safety across every intervention. As members implement, the Clinical Lead monitors response through ongoing measurement, adjusting in real time. What each member receives is tailored to their data, their response, and their history. Nothing is static. Everything is tuned.
04
Continuous Review
Measurement & Refinement
At the close of the quarter, follow-up diagnostics measure what changed. The Clinical Lead documents which interventions continue, which are complete, and precisely how the next quarter's protocol will build on this one. Our protocols are living documents. They evolve with real-world cohort data and advancing science.
What a member receives in their second year will reflect breakthroughs that hadn't happened when they started.
Here is why this is the right moment to be doing this work.

The downside of acting is a healthier body. The upside scales with every breakthrough that arrives.
This is the context that shaped what we're building, and who built it.
The Discovery
The Infrastructure Didn't Exist
For years, a highly detailed document called Eric's Health Stack circulated privately among founders, investors, executives, and athletes. It was a systematic record of one person's rigorous approach to health optimization.
As the document gained traction, the responses revealed a shared reality. Managing your health at this level is profoundly isolating. Even excellent physicians lack the bandwidth to debate emerging clinical trials or troubleshoot the granular side effects of a new peptide. Outside the clinic, you are entirely on your own.
The demand was not for more information. It was for the operational support to execute it. But the infrastructure didn't exist. Healthspanners is how we built it: a compounding sequence of highly vetted protocols, a dedicated clinical team personalizing each program, and a peer group doing the same work from the same baseline.

The work is clinical. The reason it sustains is the people doing it together.
The Community
The Reason It Works
Health optimization has always been a solo endeavor. A personal doctor, personal research, personal willpower.
Healthspanners changes that equation. Each cohort is matched by goals and life stage, all on the same protocol, on the same timeline. The people around you are high-agency, high-intent, and bring the same rigor to their health that they bring to everything else.
Matched Cohorts
Matched by goals and life stage. Same protocol, same timeline. Structural accountability at a scale that actually works.
Shared Learning
Someone whose sleep architecture responds dramatically to a protocol adjustment becomes an insight that informs the entire cohort's approach. The more we share, the better everyone's interventions get.
Commitment by Design
Same timeline. Same measurement cadence. Someone notices if anyone disengages. The cohort is why things actually get finished. Willpower is replaced by structure.
Depth Over Time
Over quarters and years, your cohort becomes something rare: a group of people who understand each other's health at a depth that almost no one else in your life ever will.
The community is not an add-on to the clinical work. It is the reason the clinical work gets completed.
This is not a networking group or a wellness retreat. It is a clinically supervised community of people doing the most important work of their lives, together.
Three years is the frame that gives the work its structure.
The Arc
Three Years. Three Phases.
Every member has a personalized baseline protocol running continuously alongside the group quarterly protocols.
Year 1
Foundations
The first year establishes the metabolic, cardiovascular, sleep, and hormonal foundations that every other system depends on. These are the substrates. Get them right, and everything downstream responds better.
Q1
Metabolic Health & Body Composition
Q2
Cardiovascular & Vascular Optimization
Q3
Sleep Architecture & Stress Resilience
Q4
Hormonal Architecture & Neuroendocrine Optimization
Year 2
Deep Systems
With foundations in place, Year 2 addresses cellular energy, the gut-brain axis, cognitive performance, and environmental burden. The clinical team's interventions get more precise with every quarter of data behind them.
Q5
Mitochondrial Health & Cellular Energy
Q6
Gut Ecosystem & Nutrient Gateway
Q7
Cognitive Performance & Neuroprotection
Q8
The Exposome: Burden, Clearance & Adaptation
Year 3
Advanced & Regenerative
Year 3 deploys the most advanced protocols available in outpatient medicine — cellular senescence, immune reconstitution, autonomic resilience — with over two years of longitudinal data informing every decision.
Q9
Cellular Senescence & Senolytic Clearance
Q10
Immune Resilience & Cancer Risk Reduction
Q11
Nervous System & Mental Resilience
Q12
Longevity Integration & Forward Architecture
The sequencing is deliberate. Foundational systems first. Deeper systems next. Advanced interventions when the biology is ready. By the end of Year 3, every major system has been systematically addressed.
The science doesn't pause while the protocols run.
The Intelligence
The Science Doesn't Wait
The science doesn't wait for quarterly protocols. Breakthroughs are happening near-daily, and our research team ensures members have access to what matters before it's widely available.
They synthesize the signal from the noise and deliver it in a way that's actionable and relevant to each member's specific biology and goals. Purpose-built analytical tools surface patterns that inform smarter protocols with every passing quarter.

Cohort Insight
GrimAge delta patterns across the Q9 senescence protocol cohort: three-quarter comparison
Every member's health data lives in a longitudinal platform designed to reveal what quarterly snapshots never can: trajectories, response patterns, and cumulative gains across every system addressed.
The data gets more valuable over time. The protocols get more precise. This is what it looks like when the infrastructure matches the moment.
Longitudinal Health Trajectory
The system is built. The membership is how we access it.
Membership
The Investment
For three years, we stop doing this alone. The clinical team, the cohort, the quarterly protocols — this is the infrastructure for a practice that deepens every quarter.
Every quarter compounds on the last. The investment does, too.
