    A true nightmare came to my life 6 months ago in the form of Dr. Samira Seini who practiced 16 Crowns that for some reason she refers to as veneers, when they are really crowns (they are 2 completely different things). She’s a very unprofessional, incompetent Dentist. In my personal case there were many errors practiced on me that resulted in many physical effects due to excessive anesthesia. During the last 6 months these SAME 16 crowns, she cemented on 3 different occasions that resulted in over 20 visits to her practice. Due to numerous errors that resulted of: margins, color, size, gaps and of course PAIN. Logically as a patient of hers I grew very frustrated about this case.
    In my PAIN ridden teeth right now I have my lowers with some temporaries and some with different colors and bad margins.
    Uppers I have a bridge with gaps, margins and another one with different color and size. Which I have proof of from pictures, messages and witnesses.
    On June 26 I had appointment with Dr. Samira however she decided to no-show therefore her assistant practiced the cementing of 1 crown which Dr. Samira never checked on before or after. That crown resulted again with different color, size and pain. Since that date she has yet to return any of my numerous calls and messages. I have even taken the time to physically look for her at her office but she’s never there when I show up. So I’m not even sure if she’s even a practicing Dentist anymore? At this point my case now must be redone by an actual professional Dentist.
    I am so upset and frustrated with how this procedure resulted as it took so much out of me: effort, money, time from my professional and personal life. Not to mention all the mental stress caused has taken its toll on me.
    Please do not be misled by this very unprofessional Dentist. Please look somewhere else for professional help with this matter. And I’m still waiting for all my records …

    Set an appt on a Friday for the upcoming Tuesday at 930. 930 rolls around and no on is there. Call them, apparently they had someone not show up due to missing a flight from a class or “something out of their control” but will 1030 work? Agree to this, show up again in an hour, once again no one is there. Call again. They ask if I was going to show up, and I guess they had called in between these times to clarify that. I just showed up when you didn’t and said yes to an hour later, we already clarified. They state they will be there in 20 minutes. 20 minutes later the “dentist herself” calls me saying that she will be there in 20 minutes. oh, and also since it xmas eve the rates will be higher. Which I don’t agree with, because that was not stated when I made the appointment. I tell her that is BS, she says well sorry I feel that way and happy holidays and hangs up! Few minutes later she calls back from the same line, and it almost seemed as if she was trying to be someone else… stated that the reason things were expensive was because I was HMO not PPO and I can’t choose any dentist, and if they were my primary the first session would be free. So I got screwed because I didn’t know that about my insurance (essentially how she put it, as if I don’t know what my insurance entails)
    I had cash as well, and most places don’t turn down cash.
    So in summary, they set up a quick appointment, didn’t show up for it, didn’t show up for the same day reschedule, told me about a higher fee day of the appointment, then hung up on me, then tried to tell me about my insurance.. Oh, and they told me not to believe everything on yelp as people there just deface people. Feel like she’s more worried about her yelp reviews then actually meeting new patients
