Disappointing. I had surgery there several years ago by Dr. Greek for a deviated Septum. I was…read morenot happy with the offset of the nose, or a new "bump" in the nose either. He said not to worry, that it would get better. Well it never did. I since have seen other ENTs and they have comment on my deviated septum. I recently had another surgery to fix what Dr. Greek did. My surgeon even commented that I was lucky he was "not an expert surgeon" as he left a lot of cartilage in the nose that was broken, whereas most other doctors would have removed it. By Dr. Greek leaving it, it saved me having to have a graft, however this should never have been needed had Dr. Greek fixed my nose the right way the first time. Other than his skills at surgery being sub-par and making matters worse, the office staff was nice and friendly And... im not a yelper with a couple reviews and only posts when I'm pissed... I have lots and believe in being fair, but having to have a 2nd surgery to fix the first, is annoying and costly!

Dr. Uyesugi took the time to listen, answer my questions, and explain everything in a way that made sense. What impressed me most was not only his knowledge and experience, but also the fact that he genuinely cared about finding the right solution instead of rushing through appointments. I recently had a Eustachian tube dilation procedure, and I am very grateful for the care I received. Dr. Uyesugi made me feel comfortable and confident throughout the entire process. His professionalism and expertise are second to none. I also want to thank audiologist Melina Garay for all the effort she put into helping me. She was patient, thorough, and took my concerns seriously. It was clear that she wanted to make sure my hearing issues were properly evaluated and addressed. The entire staff was wonderful as well. Everyone was friendly, professional, and always willing to help. From scheduling appointments to follow-up care, they made the whole experience much easier. When you are dealing with hearing and ear problems, it can be frustrating and stressful. Having a team that truly listens and works hard to help you makes all the difference. I am very thankful to Dr. Uyesugi, Melina Garay, and the entire staff for the excellent care they provided. I highly recommend them to anyone looking for an outstanding ENT and audiology team.

Regardless of insurance it does not take almost nine months the schedule a procedure. I've called and been told a message is being sent to the surgery scheduled, I've called and been told a message is being sent to the office manager and to expect a call back, I've called and been told the practice manager is getting involved and I'll be hearing form them. Not a single one of these things have happened. Getting ahold of some at the practice is impossible. I don't even know if my referral is active. I'm not even sure if the doctor is taking my insurance. DO NOT COME TO CALIFORNIA HEAD AND NECK. If you're pcp refers your here have your referral redirected immediately. Don't wast your time. Doctor Banthia couldn't even be bothered to explain a procedure, he told me to scan a QR code on a brochure then told me to use AI.
