Patient Testimonial

I was recently referred to this group by my family dentist for a root canal. They got me in on the same day and proceeded with the first step of the process. I was comfortable and felt that I was good hands the entire time. The doctor and his team explained everything that was going on and continually checked on me during the entire procedure. They answered all of my questions and never left me doubting that they knew what they were talking about. I would gladly recommend this practice to my family and friends!

My daughter was very comfortable with the staff and doctor. She tends to be more nervous when visiting a doctor, but the office staff made the experience very nice for her. She was a great patient and the staff was great too.

Patient Testimonial

Dr Atar is very good at explaining the details of my situation; however, the assistant was very rough with my X Ray today. I have never been in so much pain from receiving an X Ray. She jabbed the tool in my mouth and didn’t seem to care that I was in tears and continued to keep wanting to jab in my mouth! It hurt so bad and now I have a sore in the back of my mouth! I have never been in so much pain and still is! Ruined my whole day... I just wanted to run out of there! I told Dr. Atar and he just says he was sorry but it didn’t feel genuine and asked me if this happens all the time. NO! X rays are not supposed to hurt! I’ll never refer or go back there as long as that assistant is there. I’m so mad that I continued to let her keep jabbing me until she finally realize to try a different instrument but by that time the damage was done. I’m gonna tell my dentist who referred me to them that he might to rethink sending clients there! $119 to just go home in tears..
