About · Prefusion Health

Data, plus a team that
acts on it. 

Prefusion exists because data only changes your life if someone helps you use it. We pair medical-grade testing with real, one-on-one human care.

Our philosophy

In our founder's words

Therapies are a dime a dozen in New York. What sets Prefusion apart is how we leverage the data we have access to and put it into the human management of that data. The Protocol is the data. The membership is the team that helps you act on it.

That is who we are: body composition, performance, longevity, measured with real tools and managed by real people, in person.

Who you actually see

Meet the team

Every scan is read by a person, not a portal. This is who is in the room with you.

Bryan Jonas, Founder of Prefusion Health

Bryan Jonas

Founder

Bryan built Prefusion around one idea: therapies are a dime a dozen in New York, and what actually changes an outcome is the data underneath them and the people who read it with you.

He runs the practice across all three New York locations, sits in on consultations himself, and set the rule the whole clinic works to, that nobody is prescribed anything before a DEXA scan and a full blood panel are on the table.

What we believe

Our principles

Measure first

No plan without data. We start with real, medical-grade measurement, every time.

Human care

A real team reads your data with you and helps you act on it. Not an app.

Evidence, never hype

We recommend therapy only when your data supports it, and we prove progress with retesting.

Come see what we are about.
