Called with a dental emergency and was told I have 20 minutes to get to the office and consult is $140. I called at 4:09pm and they close at 6:00pm. I can’t even drive there that quick.

I just relocated to area and was referred to Dr. Dinh by my neighbor. Dr. Dinh is caring and has featherweight hands. I was informed of my dental health and how to improve my oral health. My cosmetic dental work can not be recognized by anyone. I enjoy smiling and laughing more because I'm no longer self conscious of my smile. Thank you again Dr. Dinh and staff for making me feel so at home and well taken care of.

Amazing services with nice staffs. Dr. Dinh is fabulous. He is professional, courteous and understanding. I had a issue with a broken tooth and he helped me have it ready within 1 hour. I have been blessed by him. I have also bragged to family and friends about his work. Highly recommended. Thank you Dr. Dinh, you gave me my smile back. :)

This is the worst dentist place I’ve ever been. Ever since my first appointment I should had known this was not a professional dental facility . I was schedule for an appointment at 9 and they didn’t open till 9:35 then I waited an hour to be seen . Once I was seen they “supposedly “, took care of some cavities I just found out through a different Dentist place with a five star rating that those cavities are still there .Then they started working on two root canals without my authorization. This place is so unprofessional. I don’t recommend this place at all!

I really hate to give these people a bad review because the lady at the desk was really cool and from my observation they seem to be a mom and pop dental shop. However, that is no excuse for he quality of work that I received on my teeth. For one, the dentist is my number one place I hate to go to because of the fillings and sensitivity of my teeth. I got fillings done and it just wasn’t done to my satisfaction. I have to go all the way back to my dentist in LA to fix their work. I’m not willing to risk another botched job. I notice they have good reviews and maybe it was just me but the fact

Dr Dinh is the best doctor I have been with him a long time, many years. He is the most honest and kindness doctor I've ever been with. Dr Dinh is very patient with his explanations and tells you the truth about your examination. The staffs also help us work out a financial budget that we could afford. I 'd recommend to anyone looking for a great dentist.
