For decades, I had a trusted dental office with the most amazing hygienist. Well, the dentist, I trusted and the hygienist, both retired and the rest of that clinic I used to go to doesn't cut the mustard for me.

Quynh smiles feels like my new dental office. although I have only gotten a crown placed and one cleaning, I can say that the work is up to par with my current needs.

The office staff is professional, kind, courteous, knowledgeable, and responsive. Dr. Keene himself has great skill and for anyone needing a crown this is your guy. ONE STOP SHOP, he has the lab right there! For those of you who don't know what this means, it means that you leave with your permanent crown instead of the usual, 2 to 4 week wait with a temporary crown which often times falls out or has complication before the permanent crown gets sent back to your dentist.

Overall highly recommend this place.

My visit was scheduled to replace a crown. Although I was very nervous about the work that would be performed, the staff made me comfortable and the procedure was as pain-free as can be under the circumstances. Dr. Keene explained every step of the process. The technology he uses to make the same day crown is simply amazing. So happy I found his practice!

My visit was a quick and thorough tooth cleaning. I hadn't been Keene Smiles for some time because of the pandemic. I'm glad I went.
p.s—Kristin, the hygienist, was great!

My first visit was very efficient from check-in to check-out. Every step was fully explained and I was given choices on optional treatments. Dr, Keene is very friendly and the staff was kind. I recommend him highly.

The folks at Keene Smiles are efficient and proficient. My appointment was on time and the technician made me comfortable while she took the x-rays and did the cleaning. Dr. Keene explained the condition of my teeth in a very understandable manner.
