I am delighted to find that Dr. Perry Lui maintains the same level of professionalism, energy, and patience that he had exhibited back when I was in sixth grade and just beginning my braces journey. I recently reached out to obtain new retainers after my original broke last year and I'm happy to say to that the process was super efficient. The new location is bright, orderly, and clean. The staff were friendly and mindful; the receptionist was also detailed in providing instructions on how to find their new office within the building. Parking space is also abundant! Furthermore, I am especially impressed with their ability to follow COVID protocols. The combination of these factors made a very pleasant, efficient, and safe experience. I am confident that they will continue to be able to meet my needs should I have any future concerns regarding my teeth! Thanks for the taking me back despite years of not servicing me - it was a pleasure :) P.S. The upgraded retainer cases are much appreciated. They are super cute now!


Got my braces here and I have such straight teeth now. When I first got braces, my braces kept falling off, but they always scheduled so quick to fix them at our convenience all the time. Three years ago, I went to get them off and now, I just went to the new location two days ago to get my retainer's checked. Dr. Perry Liu is still the friendly, funny, kind, and professional human being as I remember since I was in Grade 6! He really makes you feel like he cares about you. An amazing dentist. You deserve all these amazing reviews. Also, congratulations on the new location! It is so beautiful, bright, and clean. If you need braces, here is the place to go. :) - Leanne M.


I came here for braces 15 years ago and recently came back to replace my worn out retainers. All of the staff and Dr.Lui are extremely friendly, kind and funny. I even remember a lot of the staff faces! The new location is big, bright and they take strict protocols to make it safe for everyone during COVID19. Dr.Lui does excellent work and truly cares for all the people that come in to see him. To this day, I still get compliments about my teeth and smile and I have him to thank!!! :)

Dr. Lui is very professional and patient. The invisalign done here has been effective for more than two years. I was embarrassed for not wearing braces in time a few times, but Dr. Lui just persuaded and did not blame or charge extra. The correction price here is not low but it is definitely worth the price. I am very happy to choose this clinic, so I must give it a good review!

The best decision to get my braces with Dr. Perry Lui :) The results are awesome! Front Desk Staff are also very kind and organized. Strict Covid-19 procedures are also implemented. Would recommend to anyone who wants that perfect smile
