    I’m shame to say that I haven’t been the best at keeping up with my dental care due to previous experiences that made me terrified of going to the dentist. My daughter became a patient here at this dentistry first and was extremely impressed, she then referred me. I finally came to grips with my fear of the dentist and made that phone call for an appointment. Spoke with Ms. Amy she was extremely Professional and sympathetic to my fears, she assured me that I would be in Great hands. My first appointment with Dr. Nguyen was Absolutely the BEST experience that I’ve EVER had with a dentist!!! He was extremely professional, gentle, kind to his staff, very patient with me and has a great sense of humor. The facility is/was clean, the staff was great, prompt and professional. I Proud to say that AT Dental, PC is now my Dentist!!! Thank you Dr. Nguyen and Staff.

    I have had a wonderful experience at this practice. It has been a long time since I had my teeth cleaned or taken care of. The staff is friendly and professional. Cathy was great with scheduling and helping me with my insurance. Amy took a lot of time to explain my services and all items involved with my procedures. Karen was gentle and efficient and took a lot of care with my teeth. Dr. Nguyen is great at explaining the issues and comforting at the same time. I have had fillings, extractions and scaling with no pain and great support. I have an ortho plan in place and am 100% confident in all respects. I recommend this practice for all dental needs. I appreciate not being made to feel self conscience and having a plan put in place that will help the most. Great job on everything, wonderful staff!

    My friends who have been going to his office for 20+ years recommended him highly. I live in Decatur & I'm now happy to make the trip to Dr. Nguyen's office for his expertise, care and attention I received. He is very professional and courteous. I felt very comfortable with his recommendations, & I didn't feel like he was trying to sell me on unneeded procedures. The work he did on my root canal & crown was top-notch, I'm very happy to have him as my new dentist.

    Nancy Tuyes

    The care and professionalism is unsurpassed. From the doctor to his support staff, I was treated with the utmost respect and care. I would recommend this dental center to anyone looking for a dental center with care respect and professionalism. You won't go wrong.

    The experience is always fast and friendly. DR Nguyen is friendly and a very good dentist. They are quick to make an appointment if an emergency arises. Hygienists are always friendly and gentle. The polite staff schedules my next visit, then calls me a few days before as a reminder. I have been a patient with AT Dental for 14+ years. I highly recommend the team AT Dental in the Lawrenceville area.

    AT Dental took care of me and my teeth for 4+ years. This office is extremely welcoming and I got the privilege to grow up within this office throughout my adolescent years. Thank you Dr. Nguyen!

    Dr. Tu Nguyen & his team has taken care of me & my entire family for the past 4+ years. He’s done mine & my other two sibling’s braces & all of our smiles came out better than expected! He’s also done braces for many of my friends.

    Karen, the hygienist, is also amazing. She’s so gentle with my teeth & is very thorough.

    Love this dental office & would highly recommend it to everyone!

    Dr. Nguyen has been my and my wife’s dentist for the past 17 years. He and his office staff have always given us highly personal care and professional attention. I have the utmost regard for Dr. Nguyen’s professional skills and talents. I trust him, and he has always delivered exceptional dental care at a reasonable cost.

    Thank you Amy, Kathy and Dr. Nguyen.              


    I was having a toothache and I googled the dentist. When I called Amy answered and she was very nice.

    I had my service done and the dentist was very caring and finished in a timely manner. The staff is great. I felt at home. They even called me at home to see how I was doing. I recommend this place to everyone.
    Thank you AT Dental.                                                                                                                                                                                                  


    My husband and I have been seeing Dr Nguyen and staff for 15+ years and have never been dissatisfied with their service and special care given to us each and every time. Very clean and friendly. I had an accident and Dr Nguyen paid special attention to me and concerned over my injury. THANK YOU!


    Dr. Nguyen does excellent work. He is very experienced and thorough. Cathy and Amy at the front are very friendly and professional. I've been going here for over 10 years and would recommend this place for any dental work.


    The BEST DENTIST EVER!!!! I needed major work done on my teeth. He performed my root canal immaculately. Asked questions, and truly took his time. They even did a follow up phone call. Staff is ALWAYS providing a positive and friendly atmosphere. I’ve been going for 7+ years for fillings and regular cleanings. Would recommend their services for anyone I care about.


    The best dentist and office staff ever! I switched from Nanston Dental over 15 years ago. Dr. Nguyen is amazingly good, professional and dedicated to his work. After moving an hour away from his office I still drive back to Lawrenceville for my dental appointments because he is worth it. I have recommended him to my entire family and all my friends and everyone who has visited is continuing to see him.


    Dr. Tu Nguyen & his team have taken care of me & my entire family for the past 4+ years. He’s done mine & my other two sibling’s braces & all of our smiles came out better than expected! He’s also done braces for many of my friends.

    Karen, the hygienist, is also amazing. She’s so gentle with my teeth & is very thorough.
    Love this dental office & would highly recommend it to everyone!


    I have been coming to Dr. Nguyen’s office for several years. He is the best doctor I have ever been to. I used to be afraid of dentist because I had a bad experience before. Dr. Nguyen took that fear away. He makes sure you are completely comfortable, tells you everything he needs to do. I have never had a dentist that make sure I was in no pain and ask through out the entire time if I feel any pain. He is patient with you ask if you have any questions. The office staff are very professional, sweet and friendly. They will work with your schedule to get you in.

    If he ever moves from this location, I’m going to follow him. This is how much confidence I have in him and the staff. They are like family. How much more comfortable can you get when you enjoy going to the dentist.


    I can say about Dr. Tu and the people in his office. They are very professional, attentive, they treat me very kind. The service provided for me it was really good. I would recommend them. Thanks to all of you.


    Dr.Tu and his team are amazing! As a loyal patient for over 7 years, I always feel comfortable and at ease when getting any procedure done. I have really high anxiety when it comes to any dental cleaning/exam/what have you. This Dentist office is different! They are SO patient, gentle, and kind. Highly would recommend!


    I’ve been going here for the past 2 years and the experience has been great. The staff is friendly and try to accommodate to your schedule. Recently, I went in for an emergency for my front two teeth. I was immediately looked at to check the status of my teeth. I was later informed that day that I would have to do a root canal and crown installment for my injury. The process was fast and the staff made sure to call in after the procedure to check up on me. Highly recommend this location if you are thinking about getting a routine cleaning or for other dental procedures like crown installment.


    Want to find a good dentist. Dr Nguyen takes care of you. I have inplant from somewhere the tooth loose. Got an appointment with dr nguyen Monday, he takes care of my tooth. And he saves my implant. Great dentist. AAA+++ Lots of thanks.

    7-24-2019 when I go back for adjustment when my teeth shifted. The dentist helps me fix it with a courtesy. Highly recommended again.


    Doc and his crew are great. They are precise and professional in every aspect of service. Took care of my dental needs with ease. Thanks again. See ya next year!!!


    I've been going to this practice for over 15 years and have always had a pleasant experience. The staff are friendly, and hygienists are gentle and thorough with cleanings. I needed a root canal done when I was younger, and Dr. Tu did a wonderful job fixing up my tooth; nobody can tell that I ever broke it! Dr. Tu's patience, attention to detail, and friendliness make him a great dentist.


    Love everything about At Dental! I have been going here for several years. Everybody is so friendly and they make you feel so welcome. The ladies at the front desk always greet you with a smile when you walk in. Dr. Nguyen is absolutely amazing very through and professional. He did a great job fixing my teeth and I am so happy with Dr. Nguyen work. Wonderful hygienist! I am finally able to have a confident smile. Thank you At Dental!


    Been a patient with AT Dental for 14 years on recommendation of a work colleague. Dr. Nguyen is friendly, patient, careful and a good listener. Hygienists are always also friendly and careful. The experience is always fast, easy and I get a free toothbrush. They take my insurance, so most visits only require scheduling my next appointment. I would highly recommend AT Dental if you need a reliable dentist in the Lawrenceville area.


    I have been with this practice for 15 years. Dr. Nguyen and his staff are absolutely wonderful. My entire family are patients at this practice. Dr. Nguyen has been able to care for our needs whether it be a cleaning, extraction, or orthodontic care- we are extremely pleased with Dr. Nguyen as our dental provider. I would definitely recommend Dr. Nguyen and AT Dental if you are seeking a dental provider.


    Dr. Tu Nguyen at AT Dental has provided dental/orthodontic services for me and my family for well over 8 years. He is extremely knowledgeable in the field and meticulous during each checkup. His team of hygienists never fail to impress, providing gentle and polished cleaning.

    The front-end staff are also worth noting. They are kind, make occasional conversation, and are always there to help when needed. Just seeing them puts a bright smile on my face even before the cleaning.

    I highly recommended anyone looking for top-quality dental services at an affordable rate to consider AT Dental    


    Very nice and friendly staff. The dentist is very caring and honest, they willing to work with your schedule. Highly recommended


    They’ve done great for us. I get my cleanings from Karen and she does fantastic.


    I have been a patient of Dr. Nguyen for over 10 yrs. From the moment you walk in the door to when you leave the office, I have always been there with a smile on my face. From being greeted by the the receptionist Cathy, meeting Mrs. Nguyen, to Dr.Nguyen's diligent work, I have always left the office with positive vibes. Dr. Nguyen surely is an excellent doctor and has great staff!! His gentle hands makes sure that you are not experiencing any pain at all. I'd never go anywhere else regardless of the distance or if they took my dental insurance plan. I'd refer this place to everyone!! There is something about the atmosphere at AT Dental, that makes you feel like a part of their family. Thank you AT Dental for everything!


    I have been a patient of Dr Nguyen for over 13 years. I trust him completely with my dental care. My teeth have greatly improved over the years. Now at age 52, I have had perfect checkups every 6 months, due to his knowledge and keen eyes on preventing future problems. His staff always greet you with a smile and a positive attitude. I would highly recommend AT dental to any of my family or friends.


    Dr. Tu Nguyen at AT Dental is the best! Not only is he thorough & a perfectionist at his job, he & his staff always ensures a comfortable environment. Right when you walk through the doors, you're greeted by their amazing receptionists. I was really insecure about my smile because I had a tooth that had grown out of place, but now I flash my smile everywhere! It's my favorite feature about myself. AT Dental made that happen!


    I used to have 4 canine teeth that grew out of place and I had an overbite. Dr. Nguyen fixed all of that for me and now I have beautiful teeth and smile. After my braces, I had my teeth whiten there and have since had my cleaning there too. They have been taking care of me for about 6 years. The staff is superb! I highly recommend them.


    When I moved from Norcross to Lawrenceville I tried to stay with the Dentist I had become accustomed to in Norcross. Excessive traffic and my work hours prohibited that so I decided to give AT Dental a try. They were close to my house so I said "why not?". I'm SO GLAD I DID!!! I was a little apprehensive at first because of it being in a strip mall type of setting but I was pleasantly surprised that I had judged a book by its cover erroneously. The office is immaculately clean with super friendly staff, modern equipment, professional and personable dental assistants and Dr. Nguyen is super friendly and professional. I would recommend AT Dental highly. I've never been happier with my choice in dentists.


    I got my braces with Dr.Tu Nguyen and he did such an amazing job!..he was so detailed with my teeth and he made sure my smile was perfect..he listened to my concern that I had and he fixed it. He made sure each teeth was beautiful..he did not pull any of my teeth out which mean more work for him each month when I come in ..he said if he pull teeth out I will have to wear retainer all the time, if not my teeth will go back to its original position...(I’m so glad he made that decision for me because I hardly wear my retainer)...also he did a gumectomy on me because my gum was showing too much..everywhere i go people would say (who’s your doctor). On top of that, Dr.Tu Nguyen had such an amazing personality and the staff know you by name        and is always on top of your appointment.


    Want to find a good dentist. Dr Nguyen takes care of you. I have inplant from somewhere the tooth loose. Got an appointment with dr nguyen Monday, he takes care of my tooth. And he saves my implant. Great dentist. AAA+++ Lots of thanks.

    7-24-2019 when I go back for adjustment when my teeth shifted. The dentist helps me fix it with a courtesy. Highly recommended again.


    I have been a patient for 8 years. Very pleased with the excellent care I have received at AT Dental.


    I have my braces done and it's good. I recommend this place.


    Love this office! Been going here for 10 years now! Would highly recommend it!
