What we couldn’t verify
A check we haven’t completed yet is not a mark against this provider. It just means we’re still sourcing that record. The score reflects what we’ve confirmed so far, and updates as more checks come in.
Vial describes the public record, not the provider. This is disclosure, not endorsement. Last reviewed August 1, 2026. See every source in the full report →
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.
