I got a referral from my friend to visit Hee Yon Koh Dentistry. I’m so happy that my friend referred to this doctor!! Finding a good doctor or dentist usually takes a lot of trial and error for most people. Everyone here was super friendly and reassuring from the moment I walked in, to the moment I walked out. I really liked the fact that they have good availability in terms of appointments, everything is new and clean, and the way they treated me make me feel so comfortable. One of my big fears when going to the dentist is being told everything I’m doing wrong-but not once did anyone here make me feel embarrassed or ashamed! Dr. Koh was giving me well-detailed consultation, and a very honest treatment plan about my teeth. I was able to overcome the prejudice of the dentist since I saw Dr. Koh. Good medical devices also help the overall health of my teeth. I’ll definitely be coming here for the rest of my life! I will definitely refer everyone I know to this practice. Thanks Dr. Koh!

Finally found a dentist I like! Dr. Koh and her staff are great. Went in for a cleaning and had some concerns about a cap I had and she addressed it and acknowledge that there was something wrong with it and it needed to be replaced. It was easy to make an appointment and they worked with me on the payments of the replacement cap. I would definitely recommend Dr. Koh yo anyone looking for a new dentist!

Dr. Koh is an excellent dentist.  She is knowledgeable, compassionate and thorough.  I suffer from dental anxiety.  Dr. Koh went out of her way to make me feel safe and comfortable.  She is extremely kind, calming and patient.  She took the time to explain everything before she started.  She continually checked on how I was feeling through the entire procedure.  Her staff is fabulous.  They are all friendly and knowledgeable.  I highly recommend Dr. Koh.

I would like to start by saying I have despised the dentist ever since I was young. When I decided to choose Dr. Koh as my dentist, I wasn’t sure what my experience would be like especially since I try to avoid the dentist as much as I can – I always want to get it over with. When I had my first appointment, the staff was very nice and greeted me instantly and I barely had to wait to be seen. It was a quick yet thorough cleaning and had to schedule a second visit for my fillings. The staff was very accommodating to my work schedule and made it a very simple process. Yesterday was my second appointment and I’m still very happy with my experience. She made sure I was comfortable at all times and was helpful for all the questions I had. I’m glad I finally found a dentist in my area!

Dr. Hee Yon Koh has proven to me that she’s a star in her practice. I was terrified of going to the dentist for a root canal, but she assured me that I would not feel a thing, and you know, she was right. Kudos Dr. Koh!

Does Yelp delete my review? I gave my Dentist 5 star review not too long ago, and it is gone now. hmmm. I went to see Dr Koh today for my follow-up visit, and again everything went smooth and nicely. My new crown looks much better than before and no sensitivity at all. I am definitely coming back to see Dr. Koh and will recommend everybody to come to this office.

I can’t hardly say if 5 stars are enough for Dr. Koh!!!!! Dr. Koh. I guess I can start by saying that five stars review can’t really explain quality of her work. I had been having a lot of trouble with one of my front teeth for a few years and it was a true nightmare. I was hesistant with every dentist I went to when I had to get work done because of all my previous experiences had not been enough to make me satisfied.But I have to say my stereotype was unintentionally broken by Dr. Koh. Dr. Koh and her team were so caring and accommodating I couldn’t  help but give them my 100% trust! I have to say that trust paid off because my front tooth looks like never before! I had to get a crown and the crown is a perfect match with all of my other teeth! And when I say perfect I mean PERFECT! I was shocked and blown away by her work. All that I have left to say now is THANK YOU to Dr. Koh and her team! She is just the best dentist in the world!!!!
