How we ranked
Ratings are weighted toward independent, third-party verified patient reviews. When a physician has them, 60% of the rating comes from patients surveyed by an independent third party (not chosen by the practice) and 40% from public, anonymous reviews such as Google. Anonymous reviews alone count for less, so a few posts can't carry a physician to the top. The score also weighs years since medical school and accepting Medicare assignment. Every physician here has a verified practice website and at least five patient reviews. No one can pay to change a rank. Read the full method.
