Dillon Meier, MD · A private physician practice · Florida
I'm a cardiothoracic anesthesiologist. My hospital days are spent in the heart room, where a problem that started thirty years earlier reaches the table. 7Longevity is the practice I built to work upstream of that room: a small number of Florida clients, one physician, and a system that measures, interprets, and manages your physiology over time.
I start with everything: your history, medications, prior labs and images, wearables, and what you want from the next twenty years. I build a longitudinal picture across systems that are not routinely tested, look for trends against your own baseline, quantify risk, and keep recalibrating the plan as the data comes in and your goals evolve.
No medical records are needed.
Who this is for
01
Annual labs may be normal or borderline; they may also have a calcium score, wearable data, or several recommendations. They want the trend interpreted, the risks quantified, and a clear plan to move forward.
02
They want to ski at eighty, keep the mind sharp, reduce a family risk, or perform at work. They want that goal investigated, measured, and translated into a plan that evolves as the data comes in.
03
They read the studies, track, test, and experiment, but no longer want to evaluate and revise the plan alone as results return.
Observed in practice
These are deidentified observations from individual opening investigations. Each response reflected physician judgment for that client; no result or treatment pathway is promised.
Trends against your own baseline outrank one-off normals, and I read the markers together rather than one at a time. For example, blood sugar (fasting glucose) can drift up for years while every annual report still reads normal. Fasting insulin shows how much insulin your body is producing to keep glucose controlled before eating. I calculate HOMA-IR, use a continuous glucose monitor to see average glucose and trigger foods, and work with you to reduce the risk of progressing to diabetes.
I have spent my career designing and implementing enterprise-scale perioperative quality and process-improvement projects. My protocols have touched hundreds of thousands of patients and resulted in reduced mortality, shorter hospital stays, and fewer complications.
I am Division Chief of Cardiothoracic Anesthesia at a large West Florida hospital, Cleveland Clinic trained, and still in the operating room full time. Cardiothoracic anesthesia requires me to synthesize several complex data streams and adjust the plan while physiology is moving.
I bring that same measurement, hypothesis testing, and process-improvement discipline to your longitudinal health.
How I work
An intelligence service brings together sources over time, tests their credibility, and separates signal from noise.
Each quarter I use blood, urine, stool, saliva, and epigenetics as a full-system check. Imaging, DEXA, VO2 max, continuous glucose monitoring, genetics, and other tools are added according to your goals and what the evidence shows.
Most of the advanced testing and tools I use are cash-pay and sit outside the usual insurance authorization pathway. This lets the investigation follow the clinical question rather than an insurer's coverage rules.
Quarterly measurement gives me enough feedback to make a deliberate change, see how you respond, and adjust the plan while the information is still useful.
See how the whole system works: the cycle, how I decide, and what arrives when.
The investment
Both are annual relationships. Management is enrollment in the Meier Management System. Advisory is my ongoing involvement without the expense and cadence of the full system. Everything is written down: a Roadmap within 60 days on Advisory, and a Quarterly Healthspan Review at the close of every Management cycle.
The practice is cash-pay and does not bill insurance or Medicare. Laboratory and imaging costs are itemized with no markup; other third-party providers bill separately. Advisory's year-one estimate includes two panels at about $600 each; DEXA and VO2 max are additional. No outcome is guaranteed.
I earn nothing on anything I recommend. No test, supplement, or referral pays me.
Ten Advisory seats and three Management seats.
The caps reflect my full clinical schedule. Qualified candidates join a waiting list at capacity.
The conversation takes about 20 minutes. I'll tell you whether Advisory, Management, or neither is the right fit.
