Physicians

One physician.
For as long as it takes.

Continuity is not a feature of our practice. It is the practice. You will work with the same physician at intake, at 90 days, at ten years.

Dr. Elena Marchetti

Founding Physician · Internal Medicine

I trained in internal medicine because I wanted to read the body whole. I built Signal because the system rewards reading it late. My work is to listen earlier, measure with restraint, and stay with a patient long enough to see the trajectory bend.

Clinical Philosophy

On restraint.

The hardest decision in longevity medicine is the decision not to intervene. The literature is loud; the evidence is quieter. My role is to translate between the two — honestly, and on a tier-graded scale.

On stewardship.

A patient relationship is not a transaction. It is a custody of information that compounds annually. The 90-day loop exists to honour that custody.
