GLP-1 Provider Quality Report 2026

Source population. Clinics are sourced from the CMS National Provider Identifier (NPI) Registry and Google Business profiles, then verified to have an active website mentioning weight loss or GLP-1 services. The directory contained 9,699 active clinics at the time of generation.

Trust score formula (v1.1.0). Each clinic receives a 0–100 composite trust score from nine weighted factors: Google rating (35%), review count log-scaled (25%), photo gallery (10%), GLP-1 medications offered (8%), business hours populated (7%), verification status (5%), ABOM-certified provider (4%), claimed listing (3%), and BBB accreditation (3%). Each input is normalized to a 0–100 scale before being multiplied by its weight and summed. The composite is rounded to an integer and mapped to a letter grade. See the full trust score methodology page for normalization details and a worked example.

Inclusion criteria.A clinic appears in this report only if it has at least five of nine input factors populated (data coverage ≥ 5). Clinics with sparse data are flagged as "incomplete" and excluded from rankings. State rollups exclude states with fewer than ten scoreable clinics. The national top-50 ranking breaks ties first by data coverage (more populated inputs preferred), then by Google review count.

Quartile definition. The factor analysis sorts all scored clinics by composite score descending. The top quartile is the upper 25% (scores in the top 25th percentile); the bottom quartile is the lower 25%. Per-factor averages within each quartile use the normalized 0–100 input value, not the weighted contribution.

What is excluded. Brand-name retail pricing, manufacturer self-pay programs, insurance coverage status, and patient outcome data are not part of this report. Quality here is measured as a consumer-facing trust score derived from publicly observable signals. It is not a clinical outcomes ranking.

Limitations. Self-reported clinic attributes (telehealth flag, medications offered, BBB accreditation) may be stale at the moment of computation. Google ratings and review counts reflect a snapshot at the most recent crawl. The model does not weight provider credentials beyond ABOM certification or correct for review-volume bias toward older, urban clinics. Scores are recomputed weekly.
