The Top 10 Cardiology Doctors

How This Leaderboard Is Built

Each doctor's leaderboard score is a function of (a) average patient rating on a 5-point scale and (b) review volume. Specifically, we use rating × ln(reviews + 2) so a doctor with 500 reviews at 4.95 ranks higher than one with 5 reviews at 5.0. Only doctors with a verified Cardiology specialty designation on the federal NPI Registry are eligible.

Only reviews submitted through the form on the doctor's profile and approved by our human moderation team count. The ranking is recomputed automatically as new reviews are submitted, moderated, and published.
