Ratings & Reviews
Real Experiences from Real Patients
You trust recommendations from real people. That's why we provide comments and star ratings from patients who answer our surveys after their visits to Sanford Health. Star ratings are based on a 0-100 point scale converted to 0-5 stars. Providers must have a minimum of 30 patient ratings to receive a formal rating.
