              Ratings & Reviews

              Patient ratings and comments are posted for physicians who see patients in the outpatient setting and have received at least 30 patient experience surveys. A physician will not have ratings or comments available until the minimum number of surveys are received from patients. Physicians will also not be included if their hospital, practice, or department is not yet participating in this initiative. Read more.
