    I want to start by saying that the dentist himself is fine - he seemed competent and professional…read more However, my experience with his office and billing practices was extremely disappointing, and that's why I'm leaving this review. Before treatment, the office told us that our insurance wouldn't cover much and asked us to put down a large upfront payment. Later, when we received our benefits statement, we learned that we actually only owed about 20% of what they'd asked us to pay. When we contacted the office to request a refund of the overpayment, they claimed they had not yet received the insurance payment. This was especially frustrating because, according to the insurance company, the payment had already been processed and they had cashed it within four days of the claim being disclosed. Based on my experience, I feel the office was not transparent or honest about the insurance and payment situation, and dealing with them has been one of the most unpleasant medical office experiences I've had. If you have other options, I would strongly recommend staying away from this practice because of the way the office handles billing and communication, even though the dentist himself seems fine.

    I really felt welcomed into the office and happy that this doctor took care of me for this. Him and…read morehis team really made the experience fast and easy for me. I woke up quick from the anesthesia and was sent my way home. Dr. Liu answered any questions I had and walked me through as they put me to sleep. Definitely would recommend to anyone who needs a wisdom consult, really professional, welcoming, and fun!

    My Experience With This Practice…read more Dr. Amir was the surgeon who performed my wisdom tooth procedure. I had all four of my wisdom teeth scheduled to be removed at this practice. I paid for all four extractions, and my insurance was also billed for all four. I also paid the required copay for each tooth. I underwent general anesthesia and went through the recovery and pain believing that all four teeth had been removed. After the procedure, I was told by Dr. Amir and the staff that the procedure had been completed. At my follow-up appointment, I was again led to believe that everything had been taken care of. Later, I visited my general dentist, who took X-rays and informed me that one of my wisdom teeth was still present and had not been removed. I returned to the practice and brought this to Dr. Amir's attention. He apologized and asked me to contact the staff regarding a resolution. After contacting the staff, I was reimbursed only the $136 copay associated with the tooth that had not been removed. What makes this even more frustrating is that because of this mishap, I now have to go through another extraction and another round of recovery, pain, and inconvenience--something I should not have had to go through if the procedure had been completed correctly the first time. My concern is that I was charged for a procedure that was not fully performed, my insurance was billed for all four teeth, and I was not informed that one tooth remained until my general dentist discovered it through X-rays. I am extremely disappointed with how this was handled, particularly because I underwent general anesthesia and the risks and recovery associated with the procedure based on the understanding that all four teeth were being removed

    My son was referred to this practice by our regular dentist; it took a while for this office to…read moreverify the insurance and it seemed to be questionable whether or not I would have to pay for the consultation because they didn't communicate very well about the insurance verifications. We showed up for the consultation appointment and waited for almost an hour to be seen; when we go back, the dentist was looking at 2 yr old xrays and I had to point that fact out to him because he couldn't read the date...which i though was kind of a red flag, pink it least. So, they do updated xrays and we move forward with the consultation and I schedule an appt to get my sons wisdom teeth removed. The appointment was scheduled more than 30 days out... the evening before the appointment on June 6, 2025, I received a call saying the insurance was still not confirmed and unless i wanted to pay out of pocket, they would have to reschedule the appointment. I asked them to call me back to schedule once they verify insurance. This place NEVER called back. What I have received, 2 billings for $10.93 with no indication why i was billed. I get it it's $10.93, it least its not $110.93. I paid this a month ago because I realize this place is not good and I just want them to go away. Today, August 1, 2025, I received the same billing for $10.93. I called at 330pm on a Friday and the office is closed, but the office hours are listed to be open til 430pm. The point in all this is, don't waste your time with this practice, find a better place for you or your family member to be put under and have someone cutting into your mouths.

Everyone was nice (from the front office to everyone behind the scenes). My surgeon and his assistant put me at ease even though such a minor situation. They were very understanding of my nervousness. They were patient with my questions and concerns. Office and back rooms were clean. I got there early, and they were able to bring me back within ten minutes of me getting there. Definitely would go to this practice/office again.

    Beware of this practice!! The young woman whom I spoke with to set up my oral surgery (Christina)…read moreseemed to be on drugs. Something was "OFF" from the very beginning. She could barely speak in an audible tone. After telling her my name (slowly spelling it), & my birthdate, she forgot she asked me for both pieces of information. I told her she asked for that information already, but it didn't register with her so I told her again. She offered me two dates for the appointment & I chose one date, as well as the time from the 3 options she gave me. When it came time to confirm all this information, she had the WRONG DATE, the WRONG TIME, & the WRONG spelling of my name (it was WAY OFF). I cancelled the procedure after the 5th mistake (which included leaving me on hold for 10 minutes, then admitted she forgot about me). This is NOT a practice that I would trust! Susan H.
