5 Best Rated Primary Care Physicians in Costa Mesa, CA

All the information you see here is based on our analysis of internet reviews across the three major review platforms most used by consumers during their healthcare provider selection. The platforms we selected are Google, Yelp, Facebook RateMDs, WebMD, Vitals and HealthGrades. The analysis algorithm uses the compiled data of average score, recency of reviews, number of reviews, and the sentiment expressed in the written comments. It then assigns weight to each parameter based on the available research on how consumers use reviews in their doctor selection process. This report is designed to help identify the doctors with the best overall review score in an area and does not reflect the doctors' competence.

At ScoreDoc, our objective is to save you time and resources while assisting you in finding the ideal medical institution for all of your requirements. Also, we recognize the importance of keeping medical information private, and hence we never save any information about you in a cookie. We only track how many times a doctor's scorecard was checked, not who checked it. You can save the reputation scorecard link for future use or can return and redo the scorecard.
