I had a #5 upper right infected and broken off tooth (that my dentist could not pull), so I was…read morereferred to Dr. Phuong C Huynh and was told he was amazing, gentle, kind and affordable so I made an appointment. My appointment was this morning at 10:00 am. I was extremely nervous as I always am with the dentist. I have been going to my dentist for 25 plus years and felt very comfortable with him and his staff. Since I was about 5 I've had dental work done. I had a horrible fear of the dentist so I wasn't ready to have this extraction done by a total stranger lol. Well I'm here to brag on this Dr. he was all the things I was told and more. His staff was amazing the office was so clean and the view from where I was sitting in the procedure room , was so beautiful and tranquil!! I didnt feel a thing and he was finished in no time! He explained each procedure every step of the way! I HIGHLY recommend him! I will be returning for inplants soon. They even put a blanket over me so sweet. MAY GOD BLESS YOU Dr. Phuong G. Huynh and your staff for many years doing this and helping so many and making it affordabl! ‍His name is pronounced Dr. Win. if your wondering.

I recently developed two ulcers on the roof of my mouth. Truly the most painful (and horrifying)…read moreexperience. I would happily go through child birth three times over before going through that again..... After my third trip to urgent care, multiple misdiagnosis and two rounds of antibiotic's, they finally told me to contact my doctor or dentist. I was COMPLETELY clueless as to who I needed to call. At that point, I'd missed a week of work (fortunately, I had plenty of PTO to spare) and I was basically hysterical. I contacted my dentist first thing Monday morning and they referred me to an oral surgeon. Naturally, the oral surgeon accepted my dental insurance but not my medical insurance (they weren't sure if it would cross over to medical). I still made the apt for the next day but started looking for someone who accepted both insurances. I am SO grateful I found this office. Everyone there was incredibly kind and they fit me in that morning. The doctor and was amazing. The woman at the front desk was a saint for getting me in so quickly (kicking myself that I don't remember her name.) I have nothing but praise to sing for this office! I am incredibly grateful for them.

I am very grateful and pleased by the professional services provided to me by Dr. Kim and his…read moreentire staff. They were all very kind and compassionate as well. The office is very clean and pleasant, Hannah, his assistant, was so accommodating that she even asked me for my music preference to play during the procedure. This was my second extraction by Dr. Kim. The first being three years ago. An infected lower molar was extracted quickly and the infected area was treated with no pain experienced, only a very little pressure was felt. The second extraction was two days ago. This time an upper molar broke off making the extraction more challenging. My sinus area was also involved and inflamed. Once again no pain was felt and both procedures were performed using local anesthesia. I was given the option of general anesthesia but declined it both times with no regrets. Recovery has been quick for both extractions with minimal bleeding the first half hour when changing the gauze. No pain medications have been needed for both procedures. I highly recommend Dr. Kim to all my friends and family. I was referred here both times by my regular dentist, Dr. Lawrence Wong, who only has the highest regard for Dr. Kim and his staff.

Office experience was horrible. Everywhere else I have taken my kids. The insurance is fully…read morecovered however, this place advised me the Dentist makes his own prices and does not have a set guideline for procedures. Furthermore, when we met the dentist, (this visit was for my minor Child) he spoke to her like she was a grown adult and was very over confident and had a lack of compassion. I have no doubt that the dentist is probably good at what he does, but the way we were treated also matters. I do not recommend this place.
