How HFW works · Testing-led longevity and functional medicine

We measure before we treat.

Every decision at HFW comes from your data, read with you by a clinician and checked again over time. That's why most patients are seen by secure video: the data drives the care, not an office visit.

The short answer

How does HFW work?

Book a free 20-minute call. Your clinician recommends the right testing, reviews your results with you and builds a prioritized plan. Then you choose a program or stop there. Care is delivered online and in New York and New Jersey, and retesting shows what's actually changing.

After getting my test results, Dr. Landi walked me through a number of helpful steps to restore my health.

Claudia Morante

Google review

I found out a few of my systems were aging faster than they should be, uncovered some gut issues I’m now working on… The 90-minute review with the doctor was honestly probably the best experience I’ve ever had with a doctor.

FAQ

Quick answers.

Where do I get my blood drawn?

At a lab near you or with an at-home kit, depending on the test. Our Patient Success team sets it up.

Can I use bloodwork I already have?

Yes. Bring recent results to your free call. Your clinician tells you what's still needed.

How long until I get results?

It depends on the test, usually a few weeks. You start working with your coach while you wait.

Do I need testing before any therapy?

Yes. Testing is how your clinician confirms a therapy is appropriate and safe for you, and how you both see whether it's working.

Know where you stand. Then do something about it.
