My first visit at Best Dentistry was so much easier than any dentist office I have ever been to! From the front desk to the assistant and the Dr. Everyone was very friendly, professional and cheerful that it made my feel calm and relaxed. I never thought I would say that about a visit to the dentist!! As a first time patient I wanted to know up front if they accepted my insurance and they even printed my next appointment with what my insurance will pay and my co-pay amount. I highly recommend this dentist office to anyone looking for an office that is friendly and easy to work with. Who knew that going to the dentist was fun??!! Elizabeth

This is the best place for all dental procedures. I've been to many and can rank this as my highest. Dr Koo is great, he's patient and the procedures have all been comfortable. The insurance system is super transparent and the staff is kind and always follow up on dental cleaning appointments which is so helpful! They were able to get me in immediately when I was in pain! Overall highly rate this place and super grateful I came across it! Icing on the cake - they have cute animal videos playing!!
I went to Best Dentistry because our dentist office (where we have gone for nearly 40 years) no longer takes our insurance and their best hygienist in the world (who i’d be will ih to pay out of pocket for) no longer works there. I choose Best Denitistry because of excellent reviews online. I’ve only been once so far but am very pleased with the following things- - it was easy to make an appointment with no long wait - front desk people were friendly and professional - the dentist and technician were friendly and professional and listened to my concerns and addressed my questions. - the dentist himself cleaned my teeth and nearly matched my former hygienist in gentleness and thoroughness.
I immediately felt welcomed at the front desk with knowledgeable and personable staff. The xrays were done with gentleness by an assistant and Dr. Ruben did a thorough cleaning with the ultrasonic device, consistently checking in with me to make sure I was feeling comfortable. Another assistant polished my teeth and that was gentle as well. All areas of concern were discussed with me and shown with camera images so I would fully understand. Thanks for a great first visit!
Do you need a new dentist? Go here. Don't want to change your dentist, still go to Best dentistry! They are exactly like their name - BEST! Dr. Kim is not only the best doctor, he's also funny, friendly, and the kindest human being. All other employees be it the front desk (Isaiah, Riley!) and dental assistants (Bri, Jen), they are all rockstars! Everyone is the best at what they do!
