Counted from their Google reviews up to September 2026. Something shows here once at least 3 patients mention it. Bigger clinics get more reviews, so compare with care. Google’s rating and review total change every day, so we round them down (like 4.5+ stars or 250+ reviews) to stay accurate until our next update. See today’s reviews on Google ↗
