    If you're searching for a dentist, I highly recommend you visit Dr. O'connor and her staff. Trust me, you're in good hands.

    Everyone needs to report San Bruno Avenue Dental Group here if you have had a terrible experience…read more There's a lady who is taking X rays and directing it into my eyes and entire face with no protection. Also, they are charging beyond what the insurance is covering, and not explaining clearly on the overcharges. You will see a lot of customers complain in person. Front Desk ladies such as Crystal or Erica will disconnect your phone call intentionally and don't want to help. Unprofessional and questionable ethical violations to the patients. I am working with senior ranked people in Dental Regulation to help other victims that have also suffered. Also, whistleblowers at the company are protected when reporting on practices. Please see below and make the report. Report to: 1) Dental Board of California (under Department of Consumer Affairs): Handles complaints against licensed dentists/dental offices for issues like fraud, improper advertising, or incompetence. They investigate violations of the Dental practices and fraud allegations. 2) Delta Dental (the insurer): Report suspected provider fraud or abuse directly to them. They have an anti-fraud hotline (e.g., numbers like 800-526-1852. You can submit details of the incident, and they may investigate the provider's billing behavior. 3) Federal Trade Commission (FTC) for deceptive business practices (file at ftc.gov/complaint) 4) You can escalates to potential insurance fraud, the California Department of Insurance or NICB (National Insurance Crime Bureau) hotline (800-835-6422). No one should be victims. Please read the other 1star reviews and you can see other people being harmed. This Clinic is run by Justin Tin and Peter Lam. Michael is no longer with the company.

    Mission Dental is by far, the best dentist I have ever had in my life. They are extremely…read moreprofessional, skilled, and the customer service is exemplary. Dr. Ordonez and her team have given me many valuable recommendations for preventative care that have truly improved my dental health. They take the time to explain every procedure in detail, answer all of my questions, and make sure I feel completely comfortable before moving forward with any treatment. What really sets them apart is how genuinely caring and attentive the entire staff is. From the moment you walk in, you're greeted with kindness and treated with respect. Appointments are efficient and on time, and the quality of work is outstanding.

    I went to Mission Dental Group for a lower premolar filling on Feb 10, 2026 with Dr. Rosa Marie…read moreOrdonez. The visit was because a prior filling had come out while flossing. As a concerned patient, I asked for basic guidance on proper flossing technique so I could avoid this happening again. Dr. Ordonez refused and said that kind of education is "usually for cleanings" and that I should schedule one instead. That felt dismissive given it was directly related to why I was there. During the procedure, an instrument contacted my upper tooth and Dr. Ordonez said "sorry" at the time. That evening, after the numbness wore off, my wife noticed a chip on that upper tooth that wasn't there before. The next morning (Feb 11) I called the office to report it. The practice manager/front desk (Randy) was dismissive and said, "we don't know when we can get you in," and suggested 2 PM. I explained 1 PM was the only time I could make due to work. He said "maybe we can get you in" and wouldn't confirm until I called back again and pushed for it. Before being seen, I told the front desk I was uncomfortable returning to Dr. Ordonez and asked to see a different dentist. That request was refused. During the Feb 11 visit, Dr. Ordonez was defensive and denied responsibility. When I said her instrument hit my tooth the day before and she had said "sorry," she said she didn't remember and would need to "check her notes." I was also told the notes weren't even completed yet, which didn't inspire confidence. When I asked if the edge could be polished, she said she didn't want to because I would "just come back and complain that it's too short." She also said words to the effect of, "I can't help it if you don't take good care of your teeth," which felt like blaming me rather than addressing what happened. The tone was dismissive and confrontational. A small composite repair was placed, but the way this was handled--from the front desk to the dentist--was not professional or patient-centered. I escalated this to the owner, Dr. Growney, and his response was to defend the office and minimize what happened rather than address the conduct, the refusal to let me see another dentist, or the dismissive communication. The overall message was essentially: "We did nothing wrong," which felt like enabling this behavior instead of holding anyone accountable. Mistakes can happen. How you handle them matters. In this case, the defensiveness, refusal to accommodate, and dismissive responses from the dentist, the front desk, and the owner were the real problem. Based on this experience, I would not recommend this practice.
