I was dreading going to the dentist even though I knew I needed some major dental work done. I tried multiple other dental offices but left them all in tears. Dr. Alex was very patient and was able to make me feel comfortable. His office staff from beginning to end were top notch. I wish I would have just come here first!

No actual work done yet but everything thus far has been honest and up front with no hype or attempts to upsell with unnecessary extras. Dr. Nguyen is very personable and understanding of your circumstances. I have appointment in two weeks, so will know more then... Hopefully I can edit this to give "5 Stars" when I get the complete experience. Right now though....seems to have an excellent beginning. Found them all to be great to deal with, which took the edge off. UPDATE 9/22/17.....Started work today and have the remainder scheduled. Very satisfied all around. Dr. Nguyen lived up to my first impressions (above) and he and his staff were all very pleasant and professional. The old crown removal and installation of the temporary this afternoon were painless. Off to a good start :) 5 Stars. UPDATE 11/14/17......Have gotten a lot more done over the past two months (two lower extractions, bone grafts, root canal and crown, deep cleanings and two fillings, plus a permanent upper and temporary lower partial), all done with little or no pain. Permanent frontier crown looks great and matches perfectly.....what's not to like? Dr. Nguyen and his entire staff have been great for me...still "5 Stars". Now just waiting for the implants. Update 7-23-18: Another painless visit to prep for final implant crown installation in another 3 weeks. Almost done now! :) Update 8-14-18: YAY!!! Got both implants put in today and am very pleased with the result! As always, Dr. Nguyen's expertise and excellent staff (Liberty today) made it a smooth and painless ordeal. Glad the wait is over, they look and feel great. Couldn't want more than that.....:) Update 1-23-19: Had an appointment today for cleaning and checkup. As usual, Cat the excellent Hygienist did a fantastic job!!! She's very professional and observant in making sure your mouth stays healthy and addressing any issues she might find. Also, she's a great teacher, I've learned a lot from her and have been better off all around in my hygiene because of it. Teeth are clean and mouth feels fresh....I'm happy, and we'll do it again in six months 😁 Entire staff at "SMILES BY ALEX" is excellent to deal with. You don't see that often enough these days. Update 11/19/19: Another appointment with Kat... As always, very pleasant and thorough. She keeps me in line with my care and brushing technique and I take it all to heart. As a result my oral health has vastly improved in the three years I've been a patient. I really appreciate all she does! From the Front Desk on back, EVERYONE has been great at what they do!! 7/16/20: Appointment to finish prep for implants. Went well as always. Implants should be in soon. 11/27/20: Went last week for renewing the small coffee stained old porcelain fillings on two front teeth and WOW!!, what a difference! I was totally ecstatic. PERFECT match and completely natural in every way. Really improved my smile more than I would have ever guessed it would. Dark spots are gone!! Dr. Alex and his able Assistant Thanh performed the work....no pain as usual, so that's always a big plus 👍. Update 9/15/23: Cleaning appt. today with Kat....and as always, very thorough. She can catch ANYTHING and has been great in that regard! Today, she caught a loose implant which I had no clue about. Have been going there since 2015, and they still have virtually the same super competent staff...that speaks volumes!!!! Another 10/10!! .Update 7/2/25: As can be seen by my previous reviews over the past several years, I think very highly of Dr. Alex and would not hesitate recommending him without reservation to anyone seeking the highest level of Dental care. He's never failed to deliver and along with providing the very highest quality dentistry is both honest and approachable. Perfect combination!!

I have been going here ever since the office was at the original location. Everyone here has always been good to me and I would recommend going here! As long as you follow what your dentist tells you to do your visit should always be quick. However, we all know life happens and sometimes you have to get other procedures done! So if you need a new dentist, try out Smiles by Alex. I am sure you will be happy you decided to step foot in their office!
