What Partly Checked Means for Longevity Medical Clinic

8 of 9 named clinicians matched to current Washington professional license records. Last checked October 6, 2026.

Partly checked means we could not confirm every part of the Verified rule for this clinic, which is not a finding that any clinician is unlicensed.

It is not a rating of skill, safety or results, and it does not cover anyone the clinic does not name.
