    I've never had more pain in my life until Dr. Duffin. He cares little about cutting you up and leaving you with nothing for the paun.

    I used to go to his dad. Now I'm going to go to the son Ron. His office staff is one of the nicest I've met, very helpful. Thanks

    Dr. Ko is AWESOME! She is really great in explaining how things are going to be done. I recently…read morehad a tooth extraction and temporary bridge work done. She was great in explaining how to care for my area that was worked on. I recommend her to anyone who's in need of dental care. Anna Brown

    My mother had a crown placed by Dr. Judith Ko and has been complaining of pain for months…read moreafterward. Despite repeatedly bringing up her concerns, the pain continued to worsen. She expressed in April to Dr. Ko she was experiencing pain in the tooth and was dismissed. Two weeks ago she returned for a cleaning and expressed concerns of it hurting and being swollen and she told her that her bite was off and she reshaped the crown. My mom continued to express concerns of infection. This morning, she returned to the office because the pain had become so severe that she could no longer eat. She told Dr. Ko she was concerned the tooth was infected and worried that, if left untreated, it could progress to sepsis. Rather than taking her concerns seriously, Dr. Ko laughed. She referred my mother to another dentist "for peace of mind." When my mother asked if the office could call to help get her seen urgently because she believed the tooth was infected, Dr. Ko told her it made no difference whether the office called or she did. Thankfully, my mother contacted her previous dentist after leaving the appointment. Within hours, they arranged an emergency appointment with an outstanding endodontist. By this afternoon, she was already being treated. What was suppose to be an emergency assessment became an emergency procedure. During the emergency root canal, the endodontist found that all four roots of the tooth were infected. He rated the infection an 8.5 out of 10 in severity and said he was surprised she wasn't much sicker or in even more severe pain considering how extensive the infection was. He also explained that, had the infection continued untreated, it could have progressed to a life-threatening infection. The complete lack of urgency, compassion, and willingness to investigate months of ongoing pain is incredibly disappointing. Had my mother accepted being dismissed this morning instead of seeking another opinion, the outcome could have been far worse. I hope future patients' concerns are taken seriously before they reach this point.
