Our patients leave smiling
My husband and I had appointments for 9:00 a.m. and 9:15 a.m. on August 30th, 2017. As soon as we walked in the Patient Administrator was very cordial and personable and confirmed the reason for our visits. X-rays were taken almost as soon as we arrived and our check-ups were done by Dr. Susan Lobaton-Palacios. We are very satisfied with the service provided. Dr. Lobaton-Palacios has been our dent…
Dr. Ponquinette was amazing!!! I was terrified about getting my tooth extracted and was worried that it would be painful. But with his caring and humorous personality, he made the whole process quick and painless. Definitely recommend ADC; inside is super clean/neat and very friendly staff.
Very friendly, professional, clean office, professional receptionist, and overall all a nice experience. Dr. Lobaton-Palacios and Dr. Goldstein was the best! Explained all the procedures, didn’t make me feel nervous or anxious about my treatments, and took good care of me. The dental techs also provide great care and pre-treatments on every one of my visits. The billing office was also frien…

First time at American Dental. I received a warm welcome as soon as I walked in the door by Kathryn. Staff is very warm and knowledgeable. Keishy took my x rays which are usually painful for me because I have an extra bone in the roof of my mouth. But as soon as I told her that, she positioned the equipment so that I had virtually no pain at all. I felt comfortable with them. Loraina was also very…
I love the staff, they treat you as if you’re family!! They are very friendly and caring. As soon as you walk in the door, you are welcomed. The receptionists are all professional and kind.

I have been going to American Dental since 2000. I love the service it is excellent. Everything I go it gets better. I had Karen as my hygienist and she was wonderful and very thorough and made my teeth look super clean. Dr. Goldstein is a gem. The exam was thorough and very professional. The lady who took my ex ray was great. She was super busy but did it with a smile. Everyone at American Dental…
Utterly Amazing. My whole family has gotten work done here and they’ve done nothing but treat us with great bedside manner, kindness, and great work. Dr. Ramasway is the best orthodontist anyone can ask for. He is great and so personable
I love American Dental Center. Not only are the doctors and staff friendly and helpful, but they also work with you when it comes to paying your bill. They also calculate future cosmetic procedures, and contact you insurance to see how much they will cover. It takes the hassle of researching for yourself. Also, Karen is such a professional and a sweetheart. She is not only concerned with my cleani…
I’ve been coming here for years! Always great, quick, and easy! Highly experienced staff! Would definitely recommend!
Outstanding! Dr “Paltec”, Karen, Melissa, Maria and Carol are amazing. Professional, sincere, and understanding . Always provide amazing results while being totally informative on all procedures. Very client friendly, and make you feel like family! thank you, thank you
I’m currently sitting on a chair receiving grade A service from Carmen who is prepping my procedure as I wait for Dr Lobaton. Keisha was phenomenal, funny, and patient while taking my x-rays. Been coming here for years and the service and the people always exceed my expectation. Dr Lobaton did a high quality job on a root canal that I had A bad infection on some time ago and now I’m ba…
practice works like clockwork. everyone was kind and professional. Perfect cleaning by Madi, comfortable x-rays taken by Charkisa, Dr Paltac was perfect ad knowledgeable. The front desk ladies were wonderful. I will tell everyone to switch to American Dental in Union.
Been coming here for years my whole family and loves the staff and they make us feel welcome everytime. They have payment plans and everything. When my son’s insurence wouldn’t cover the work they worked with me each month until I was at a zero balance. I’m grateful for all they have done .. my family have great teeth because of them. Thank you
Always a great expereince. Treated with professionalism and never a long wait. The information on file is complete and accurate, and the dental work is first class. I have had many experiences with dentisits and practices, I rate this as one of the best. Keep up the good work!!! Dr. Lisa Cleveland
Over 10 years as a patient, Me and my family have enjoyed exceptional consistent professional services from America dental center. Orthodontist (Dr. Ram) and his team and rest of the other dentistry services are Top rated family dentist.
I am very happy with my Dentist. My experience has been great. I find her to be caring, attentive, polite and most of all very professional.
Usually I don’t like going to the dentist (who does). However, the staff here is very friendly and they are very quick too. I had a cleaning and x rays in under an hour. For years I dreaded the dentist, but I finally found one I will definitely return to and refer friends to as well.
Doctor was very patiented and constantly asked was I okay, as well as the dental assistant. It was a very pleasant experience. I would definately recommend family and friends to this dentist. Very professional and compassionate, just a pleasant experience all around for someone afraid of having dental work done like myself.
Just for someone thinking about going here don’t second guess your self just go, this is the best place I’ve been in my life the staff is great service on point wait time excellent i would recommend American Dental Center to everyone . My one point of emphasis is i was not offer a discount even though i had insurance
I was beyond Nervous… After being talked to explaining what was getting done.. The dentist assist helped me calm down & the experience wasn’t as bad as I thought.. AMAZING STAFF ! Thanks..
I have been going to American Dental Center for 9 years. They provide a courteous service from the receptionist to the hygientist and dentists. I feel very confident in their practice and procedures and appreciate all of them. You always leave there on a positive note!!! I would recommend and have recommended them in a heartbeat!!!
I came in after having had substantial pain over the weekend. I was frustrated – and probably not easy to deal with. The front desk, together with Lily, and the dentist, were incredibly patient with me and provided quality customer service, resolving the issue within 2 hours. Incredibly professional and accommodating. I am very satisfied with this office.
The entire staff from front desk to the Dentists are professional & make you feel comfortable ! I am a new patient and I’ve finally found a solid dental office ! They have the total package !
Staff is very professional and friendly appointments are kept close to the time they are set for Very happy with the quality of their work
