Healthspan isn't a supplement stack — it's the unhurried integration of metabolic, cardiovascular, cognitive, hormonal, musculoskeletal, and emotional health, watched over time by one clinician who knows you.
Members enroll annually. Onboarding is four hours, in person.
Continuous glucose monitoring, advanced insulin testing, and personalized nutrition planning. The single largest lever for healthspan, and where most clinical care quietly fails.
Apolipoprotein-B, Lp(a), and CT-CAC every five years. We treat ASCVD risk decades before it shows up, calibrated to your genotype and family history.
Annual neurocognitive testing, sleep study, and an active prevention plan. Most dementia risk is modifiable, but the window narrows quickly after fifty.
Comprehensive endocrine evaluation across thyroid, adrenal, and sex hormones — for both women and men. Bioidentical when indicated, never as a default.
VO₂ max and strength benchmarking with quarterly retesting. We program — alongside your trainer — for the body you'll need at eighty.
Stress, sleep, and relationships are clinical inputs. We work with vetted therapists, dietitians, and coaches as one care team.
Lumen began the year I stopped seeing my patients. After fifteen years in academic internal medicine, I had on average twelve minutes per visit. Most days I was practicing a kind of triage that no one had taught me to call medicine — and certainly not longevity.
Lumen is what happens when you turn that math around. Four hours for the intake. Forty members per physician. The labs you'd actually run if you could. The conversations you'd actually have if anyone gave you back your afternoon.
All Lumen physicians are board-certified in internal medicine and trained in functional or longevity medicine fellowships. We are deliberately small, and accept thirty new members each year.
Four-hour history, biomechanical assessment, full body scan, and the most thorough lab panel you've ever had.
A written plan, ten to twenty pages, with numbered interventions, expected timelines, and which we'll actually do first.
Quarterly visits, monthly check-ins, and the ability to message your physician directly. Adjustments live in your record, not your inbox.
Annual re-intake. We measure progress against last year's numbers — not population averages — and quietly hold the wins.
A clinical primer on the single most actionable cardiovascular marker — what the evidence really says, why the threshold dropped, and the order in which we treat it.
Why glucose variability matters more than any single fasting number — and what you can actually do about it before lunch.
Architecture over hours: REM, slow-wave, and the small adjustments that move them — without sleep medication.
Members enroll for a full clinical year. We'll respond within two business days with a brief screening call and your intake calendar.
