What Vial measures, and what we don’t
We evaluate public records: federal enforcement history, registrations, certifications, and how transparent a provider is about its clinicians, pharmacies, and pricing. We don’t score bedside manner, clinical outcomes, or customer satisfaction, and we don’t collect user reviews.
