About Elena

I spent eleven years in a hospital risk unit seeing people after their first event. Most had a normal cholesterol on their last check. Many had an ApoB that would have told a different story, and nobody had measured it.

Kerno exists to measure it earlier. I set the panel, the targets and the rules for when we act and when we wait. I read every lipid panel before it reaches a member.

I do not think a longevity clinic should promise years. It should tell you, with numbers, where you stand and which of those numbers you can move.
