I had asked my dentist for a referral to an orthodontist as over the years my teeth had shifted after having braces during my teenage years. Imagine my surprise when he referred me to Kai Orthodontics. Dr. Kenneth Kai had been my orthodontist the first go around! When I went in for a consult, I learned that Kenneth Kai had recently retired and his sons were now running the practice in the same office I had been to as a teenager. Drs. Alan and Marcus are amazing! Both of them always took the time to explain every step of the process when I decided to go with Invisalign. I was very pleased with the whole process. Also, the office staff and technicians are top notch, very personable, and extremely knowledgeable. I highly recommend Kai Orthodontics!

We were very happy with Kai Orthodontics. Doctors and the staff are exceptionally knowledgeable, warm, caring, and very accommodating. The work they produce is outstanding and the price is very reasonable with flexible payment terms. We were referred to Kai Orthodontics by our family dentist as well as by friends, and although their office was not located near to our home, we felt it was well worth the drive. Would return and highly recommend Kai Orthodontics to anyone who asks.

Super happy with my results! I had terrible overbite originally along with pretty lopsided teeth but after two years only, all my issues were fixed. I was expecting at least three years but it was fixed very quick! Staff are all very friendly and very time flexible too.

I had been a patient of Dr. Kenneth Kai about 10 years ago and he was a very detail-oriented and dedicated orthodontist. I had a wonderful experience with him. I recently returned to remake my retainers and his two sons are managing the practice. They are very professional and just as caring and dedicated as their father. Communication with the front desk was also very efficient and smooth. Amazing service then and now from the doctors and their staff!

I had an amazing experience with Kai Orthodontics! I had metal braces for about 3 years and also needed double jaw surgery, and Dr. Kai did an incredible job coordinating everything with my jaw surgeon at Kaiser. The entire process felt seamless and well-managed. After my surgery and once my braces came off, Dr. Kai and his sons took the time to make sure my bite was absolutely perfect. I really appreciated the level of care and attention to detail throughout my treatment. The front desk staff is always super friendly and helpful, and it’s very easy to schedule or reschedule appointments when needed. The dental assistants are also fantastic and make every visit comfortable. Overall, I couldn’t be happier with my results and highly recommend them to anyone looking for orthodontic care!
