Dr. Yeh is the most conscious dentist I know. I never gave my opinion before but after reading a negative review I had to chime in.I feel he is only concerned about doing the best work possible. I know if he feels the dental treatment wasn't up to his standards, he would do it over until he & the patient are satisfied. Honesty is very important to me. I trust Dr. Yeh and feel his treatment & fees are as good as it gets. Some people can't accept the truth. I think this is why some people write negative reviews. If I didn't believe this I wouldn't be his patient for over 25 years.
