I was diagnosed with a Parathyroid tumor a few years ago but was afraid to have surgery. Dr. Yeh was highly recommended and I happened to meet a couple of people who had surgery by him. I decided to come to UCLA from Orange County and my experience with Dr. Yeh has been wonderful from consultation to surgery to post-op visit. I experienced hardly any pain and returned back to work four days from surgery. I would highly recommend Dr. Yeh and UCLA medical center.
