    Total scam. Tried to charge me $750 for teeth clean ONLY and that's with insurance. LMFAO. I wouldn't recommend this office.

    Based on the reviews, I was expecting and looking forward to a 5-star experience. Unfortunately,…read morethat was not my experience, and I felt I was given 1-star treatment. The female dental assistant was not welcoming or friendly. When I mentioned that I wanted to skip the CBCT scan due to financial reasons, as the cost can be hundreds of dollars depending on insurance, she continued to push the scan 4-5 times despite my clearly stating that I did not want it. I found this extremely uncomfortable and felt that my decision was not being respected. When it came time for the X-rays, the lead apron was tossed onto me rather than being placed on me with care. I have pectus excavatum, which made this particularly uncomfortable and, in my opinion, was not handled professionally. My experience with Dr. Omid Dianat was also concerning. I was placed in a Trendelenburg position, with my head lower than my feet. I have cystic fibrosis and related sinus issues, which make me particularly prone to dizziness and migraine spikes. I had disclosed my medical history and symptoms in the forms I completed prior to the appointment. Being placed in that position exacerbated my symptoms and left me feeling extremely ill afterward. I understand that certain procedures and positioning may be necessary, but I believe my medical history should have been reviewed and taken into consideration before positioning me this way. At the very least, I would have appreciated being informed beforehand so we could discuss whether there was a more appropriate position for me. Additionally, when the electric pulp tester (EPT) was used on an already extremely sensitive tooth, I would have appreciated even a brief warning that the test could cause significant pain. A simple 10-second explanation would have made the experience much less distressing. Overall, I left feeling genuinely disappointed because I had high expectations after reading so many positive reviews. I was hoping to feel heard, respected, and cared for throughout my appointment, particularly after taking the time to provide detailed information about my medical history and concerns beforehand. Instead, I left feeling that my decisions, comfort, and individual needs were not given the level of consideration I expected. I'm sharing this feedback because I believe these concerns could have been addressed with better communication, more attentiveness, and a little more compassion. I hope the office takes this experience seriously and considers how these interactions can be improved so future patients feel more comfortable, respected, and cared for.

    What more JOY could we experience than going in for a root planing and scaling on a Monday…read moreafternoon? Ummmm ... no thank you! But if it must be done, it must be done. I have severe anxiety ever since a dentist hurt me 19 years ago during this very procedure. I didn't go back to ANY dentist for 9 years because of that. Yes, I know, I know. And yes, I paid dearly for that. But eventually I was able to get the health back to some sense of normal ... and back to regular maintenance. And lo & behold, maintenance rolled itself back around to this SAME procedure again. Had a major panic attack in the chair today. Yes, I did. Tears, shaking, and that relentless desire to run screaming from their office. But Dr. Kim and his staff are amaaaazing. The kindness and care they showed me was immaculate. Did I mention this was a pain-free visit? Yeah, pain-free. You'd think I'da just sailed right through! What's the big deal? But there was that one day 19 years ago ... the reptilian brain is masterful at digging up old fears, isn't it? I just wanted to give a "Bravo!" publicly. Because who doesn't LOVE a pain-free and KIND dental experience?
