Our Reviews

Our patients are our biggest fans. Here's a few highlights from our public reviews:

Paul is a consummate professional and an outstanding dentist. He takes a meticulous, thorough and holistic approach to dentistry - while my first visit was a bit rough, he helped me realize precisely how to improve my oral hygiene in order to meet his high standards. Every visit afterwards was nearly painless. The guy knows what he is doing, and he is invested in every aspect of his patients’ oral health.

He is friendly, knowledgeable and caring. I strongly recommend his services to anyone in San Mateo County seeking a dentist, and I wish he and his assistant Christy all the best!

Paul is a great dentist but what sets him apart, aside from being incredibly patient and gentle, is his genuine care for your wellbeing and not just his bottom line.

When you step into his office you are getting the attention of a person focused on your health.

When I moved from Fremont to San Mateo, I decided to find a new dentist closer to my home. I randomly picked Dr. Paul from the Metlife website and I got lucky. He is always able to see me at 7:30am before I have to go to work. I’m pretty good about brushing and flossing so I’ve only had him do my exam and cleanings. I’m very happy with his services. And he always answers my questions in language I understand no matter how silly they are.

5 stars for Dr. Paul! Love how he gives me a really good toothbrush, too!
