After searching and searching I finally found an excellent Doctor in the Vegas area. Dr. F. Richard Tan (MD) is the best! I checked out his educational background, looked for malpractice complaints and suits, checked for medical board sanctions, and patient reviews. He couldn't have gotten any higher ratings! When I saw him he was attentive, personable, thorough, and not only well educated but current on medical studies related to my health issues. Absolutely awesome. Further, the office staff is polite, efficient and pleasant to deal with. If I could give more than five stars I would!
