Trajectory Medicine: the strategic health advantage for leaders who refuse to leave their longevity to chance.
Lahvie is intentionally small — capped to protect depth, discretion, and precision.
Built for executives, founders, and cultural leaders operating at the highest levels. We identify where your health trajectory is heading — and intervene upstream, before the slope turns against you.
The standard model of medicine is designed to catch disease after it arrives. It waits. It reacts. It manages. For most people, that's enough. But for high performers who depend on sustained energy, sharp cognition, and physical resilience — waiting for the warning sign is already losing.
Normal labs are not the same as optimal. And optimal today is not optimal in ten years. The question that matters: where is your trajectory heading — and are you accelerating or decelerating?
The Core Thesis
Trajectory Medicine measures and optimizes the biological systems that determine your long-term health slope — before disease appears. We work on upstream drivers, not downstream symptoms.
The Framework
Informed by causal inference principles — particularly the work of Judea Pearl — Trajectory Medicine identifies the six physiological regulators that determine your health arc over decades. We don't just track correlations; we target the upstream levers that actually change trajectory.
The master regulator of how your body processes fuel. Declining sensitivity is the earliest upstream signal of metabolic collapse — often invisible in standard labs until the damage is done.
The single most predictive biomarker of all-cause mortality and cognitive longevity. We treat cardiovascular capacity as a performance variable — not a fitness metric.
Skeletal muscle is not cosmetic. It is your primary metabolic organ, your insulin buffer, and the architecture of functional independence as you age. We treat it as such.
Not duration — architecture. Fragmented sleep compresses the hormonal, immune, and cognitive restoration that high performance requires. We find what's breaking it.
Your nervous system's ability to regulate stress, recover from demands, and adapt over time. The foundation of sustained performance under pressure — and the first thing to erode silently.
Processing speed, executive function, working memory. We protect the organ your career, your leadership, and your legacy depend on most — long before decline becomes visible.
The Process
Three phases. Rigorous. Longitudinal.
Deep labs, performance metrics, and a comprehensive assessment of your six physiological regulators. We establish where your trajectory actually stands — not where standard screening suggests.
We map your upstream drivers — the specific variables pulling your trajectory upward or downward. You receive a clear picture of your health slope and the levers that move it.
A precision protocol targeting your specific upstream regulators — metabolic, cardiovascular, sleep, cognitive. With a defined retest cadence to track slope change over time.
This is not primary care. This is strategic physiological optimization.
Leaders whose decisions affect thousands — and who cannot afford cognitive fog, energy crashes, or early decline.
Attorneys, surgeons, investors, operators — people whose edge depends on sustained mental and physical output.
Artists, athletes, creatives, and public figures who understand that their body is the instrument their work flows through.
Why This Is Different
We track direction, not just numbers.
We focus on upstream physiology, not late-stage disease management.
We integrate performance medicine with longitudinal data and retesting cadence.
We operate as a small, elite practice — not a volume clinic.
Physician and founder based in Los Angeles, Dr. Amos has spent over two decades focused on metabolic health, performance physiology, and long-horizon cognitive protection. He founded Lahvie on a conviction that medicine had been asking the wrong question — not "what disease do you have?" but "where is your trajectory heading, and what can we change right now to alter its course?"
He developed the Trajectory Medicine framework by applying Judea Pearl's causal inference principles to clinical practice — building a system that identifies the upstream physiological regulators that determine health outcomes long before symptoms emerge. It is predictive medicine, not reactive medicine.
Beyond the clinic, Dr. Amos is a media figure and community builder. He is the host of the Lahvie podcast and the author of a widely-read Substack on performance, longevity, and the intersection of health and culture. He also builds community around training and longevity in Los Angeles — because he believes human connection is one of the most underrated variables in the longevity equation.
