Longevity medicine
should be
good medicine.

I write about prevention, symptoms, labs, and the places longevity medicine gets ahead of itself.

A physician’s read on longevity claims.

01

Tests that change decisions

Which labs and scans are worth doing, and what to do with the results.

02

Before you add anything

When a medication, supplement, or habit earns its place.

03

When you need a doctor

The problems that need a clinician, not another article.

Longevity advicewithout miracle language.

Doctor-written guides on labs, exercise, supplements, medications, and longevity claims that deserve skepticism.

Know your biological age.

Not a wellness quiz. A structured assessment — sleep, exercise, labs, metabolic markers, and functional tests — that estimates where your body is relative to your calendar age.

Example: sleep, exercise, and metabolic markers align to shave ~5 years.

Good medicine first.

The same standard I use in clinic: good evidence, a clear reason to act, and a willingness to stop when something isn’t helping.

Know what you’re measuring

A lab is useful when it changes the decision, not because it makes the report look complete.

Results need context

A lab value only means something alongside symptoms, history, and what you’re trying to change.

Stopping is a treatment too

Anything worth starting deserves a check-in, and an exit if it isn’t helping.

Medicine, then systems.

Hillary trained at Stanford and Columbia, then built companies around the same problem: how to turn medical evidence into decisions people can actually use.

Clinical training

Stanford biology and medicine, Columbia oncology training.

Company building

Built a VC-backed mental health company and learned where plans break when real patients are on the other side.

CareCore

Practical safeguards for longevity care: physician review, documentation, and clear ways to pause or change direction.

Offering real care?

CareCore helps health companies offer longevity care with physician review, documentation, and follow-through, so patients get real care instead of content.

Physician review

Review care paths, catch contraindications, and keep decisions tied to a real clinical record.

Partner support

A way for health brands to offer more than content without pretending software is a doctor.

Clear follow-up

Documentation, handoffs, and a plan for when something should change or pause.

This is where I think in public.
