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.

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 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.
