Amazon One Medical

Names a clinical lead

A named, sourced clinical leader is publicly accountable here. LoseLab has not checked their license — the registries below let you do that in about two minutes.

Named clinical lead

Dr. Andrew Diamond, MD, PhD

Chief Medical Officer since 2019; board-certified in internal medicine (ABIM) and still practicing primary care.

One Medical — provider profile

Regulatory & legal record

We found no documented regulatory action against this platform. That is not a clean bill of health — it means our search of public FDA, court, and state-board records turned up nothing, and absence of a record is not the same as absence of a problem.

What the platform discloses publicly

The CMO is named and has a public provider profile you can open and read.
Primary care and pharmacy sit inside one company, so a single entity is accountable end to end — rather than a telehealth brand pointing at a pharmacy pointing back.

What you still can’t check

One Medical membership is a recurring cost stacked on top of the medication.

LoseLab does not verify credentials — check them yourself with the public registries.
