Dr. Koo is great! I’m so glad that I had all my four wisdom teeth removed at his place. He is so professional and friendly, I will highly recommend him if you needs to get the wisdom tooth removed!

Had a great experience removing the wisdom tooth with Dr. Koo. My wisdom teeth was growing horizontally, which it requires a insertion before removal. The entire process is fast and with no pain at all. It only take me 2 days to recover from it. If you’re looking for someone remove teeth for you, Dr. Koo will be your best choice.

Ive been going to Dr. Koo for over 10 years and I havent regretted it once! He is so knowledgeable, kind, patient, professional and caring! I used to be afraid of the dentist, but now I feel like I cant wait to go to the dentist and thats all because Dr. Koo. Making sure every patient is comfortable is one of his many good traits. He will walk you through every process so you wont be caught off by surprise. Ive been to both of his locations and both are extremely clean. That is definitely something I look for when choosing a dentist. You will not regret it if you decide to give Dr. Koo a try. I highly recommend him!

The BEST.... Dr. Koo is an amazing dentist. I have been a patient of his for 31 years and he has always taken great care of me.. I have had several root canals and crowns done through the years along with my wisdom teeth when I was younger. I trust him very much. He explains exactly what he is going to do and my numerous visits have been painless and done very well. I love Dr. Koo.. He is the BEST!!!

Back in 2003 I was shopping Dentists to pull my moderately impacted Wisdom. Each dentist, with their plush couches and fancy offices didnt want to get their hands dirty and 3 times referred me out to an oral surgeon. Someone recommended Dr. Koo. Dr. Koo offered to remove the wisdom on the spot with a Local Anesthetic for a very reasonable cash price. He had the tooth out in about 2 minutes.My wife suffered from a genetic issue and at a young age had lost many of her teeth. Dr. Koo did an outstanding job of basically giving her a new set of teeth and a beautiful smile. Implants are not covered by insurance and Dr. Koo charged probably 1/2 the going rate.My kids also see Dr. Koo, he is a nice guy and although I dont live in Arcadia anymore I always make the drive to see the only Dentist I trust.He sold his old practice and I guess is slowing down a bit, Ive followed him to his private practice and am glad he is still willing to be my dentist.

My long time friend recommended me to Dr. Koo not too long ago after hearing about dental problems. After one visit, I was absolutely sure he would be my new permanent physician. Where shall I start? Upon arriving I received the most warm welcome from his staff. They were genuinely concerned about my problems and I could tell they were very happy working there. That tells me a lot about the doc.. To have happy staff, means they are taken care of. What impressed me most was the instant replies when I text about my concerns after visits. I was also able to contact him about a last minute visit. He was able to fit me into his busy schedule. I absolutely love that I can contact him with concerns and questions, knowing that he would be be there to help. That is a rarity in itself. Thank you Dr. Koo! You have gained a lifelong patient.

I never like dentists in the states, Most dentist often overcharged for a procedure and i really hated going to the dentist. Im not a person with a lot of money, i only live paycheck by paycheck. My mom recommend me to Dr. Koo when he was still at his old dental place, He is a very reasonable man, he understand my situation and he is willing to work with me. He had worked on almost all my tooth such as root canal, crown. He did a great job. when i stop by his old place recently, it was so sad to find out that he left his old office, But i was happy when i found him on google. I will keep going to him for my dental need.

Dr. Koo is absolutely amazing. He extracted my tooth today without me having any discomfort. I highly recommend him. He is an excellent dentist and I know him for over 20 years. Thank you again.Dr. Koo extracted my husbands teeth today and he did an excellent job. My husband does not have any pain. I highly recommend this dentist.

Dr David Koo literally feels as if he is part of my family. He has worked on threegenerations— my mother, myself and my daughter. He has always been very attentive and genuinely caring towards each of us..making sure every visit is comforting.We have had fillings, crowns, cleaning done with Dr Koo, all which have been great experiences. It is inevitable that for most people going to a dentist is stressful and nerve wrecking, for my family however, it is a breeze. Highly recommend for others to pay a visit if looking for a great dentist.

My mothers friend recommended me to come here to extract teeth, when I was suffering from the pain caused by wisdom teeth inflammation. This was the first time I have pulled out my teeth for so many years. Everyone told me that it is very painful to pull out wisdom teeth, so I was pretty nervous. But Dr. Koo is really so skillful that I havent realized that I have already finished it, and I dont feel pain during the recovery process. One week later, I came to pull out my second wisdom tooth, which is also a comfortable experience. Thank you, doctor koo.

I had a root canal treatment with Dr. Koo today. He performed the procedure like a professional with decades of experience. I literally felt nothing except for the initial shot to my gums to numb my nerves. I am usually kind of nervous for these type of things but Dr. Koo made me feel very re-assured.

I have been with Dr David Koo for over 25 years, He is the best I have had.he have applied service when I didnt have all the money he even placed 14K gold in my mouth at his own coast. I will never forget his service. wish there were more of his kind. where ever he go I will need to have his office contact me for his service.

Dr. Koo has helped me gain confidence through my smile. He did an excellent job on my teeth. My dental implants were comfortable and lasted me 15+ years. Without them, it would be difficult to eat and chew. I greatly appreciate Dr. Koo’s service. Thank you very much!

Excellent service. Doctors are amazing. They help quit the paint on my wisdom tooth. A really fast extraction. Thank you.

Stay AWAY!!! My 92 year old mother had to have a crown. I did not believe her story at first but when I looked in her mouth I was appalled! I just had a crown after her experience so I know the difference between a horrible dentist and a great dentist. The crown looks like someone put a wad of gum in her mouth and left it. Not cosmetically pretty but worse it doesnt even fit her tooth!! What can be done at this point? No idea but I will seekanswers and in the meantime STAY AWAY!!

Dr. Koo has been the family dentist for over 25 years he provides the best service bar none and genuinely cares for his patients, providing my mother 12 perfect root canal with zero infections or complications, the office has some of the best dental technology staying with the times and has always put the patient first. We love you doctor Koo -The Zinn Family

Do NOT go to David Koo unless you want to put your life and health in a butchers hand! Do not fall for his used car salesmanship and have his closer close on you! Koo is a general dentist who took a crash course in implant and is not capable to perform surgery, sutures or proper anesthesia.He severed my trigeminal nerve (brain nerve) during the implant using a quick and dirty gum punch, also caused severed daily tormenting status migraine without proper anesthesia just like in the other patients root canal review. Both damages are permanent, extremely painful and crippling, which resulted me becoming a regular in ER and hospital vs. I had never set foot in ER prior to the life-altering catastrophe.Stay away from this butcher shop!

Great dentist with great service!

Terrible dentist and clinic, no professional moral.
