What Our Patients Are Saying

five stars

“The entire staff is friendly and accommodating (receptionist, hygienists, dentist). Dr. Yap is excellent with children – both of our kids actually enjoy going to the dentist.

Both hygienists my family has seen do quality work without hurting your teeth when you are finished. Dr. Yap takes time to answer any questions you have and explains any additional work that needs to be done.

We highly recommend Yap Family Dental!”

five stars

I’m not a huge fan of going to the dentist, but the staff at Dr. Yap’s office are so warm and welcoming!

I try to make sure I go when Michelle’s working. I always have the best time chatting and catching up, well as much as one can while getting their teeth cleaned!

? Highly recommend this team!”

Krystal B.

five stars

I have been to a lot of dental offices in my time, and Dr. Yap and the wonderful team he has are by far my favorite and my home. Besides Dr. Yap who is super professional, talented, and warm, the two people who I’ve had the most contact with are Terryl on the administrative staff and Jen one of their dental hygienists, and they really stand out and are the very best (though again the whole team is amazing).

Terryl always remembers what’s going on with me (just as a person) and works so hard to make sure that the insurance coordinates well and that I know what I’m paying for, which as you all may know is a big deal when you have dental needs.

Jen also always checks in with me and makes me feel so welcome, and she is such a talented hygienist who always has a great answer for my many questions. You really cannot go wrong with Dr. Yap and his team. They are amazing.”
