Dr. Siu did a remarkable job with my daughter's teeth! Not only were her teeth transformed into perfection, she also gave her self-confidence and a beautiful smile! Dr. Siu and her staff are very caring and professional! There are many, many orthodontists in the area, but we are very happy we went with Dr. Siu!

We LOVE Dr. Siu and her staff!! They are very caring and professional! Both my son and my daughter have gone through orthodontic treatment (full braces). We have been nothing but pleased with the on going treatment as well as the ending results. Thank you Dr. Siu for giving my kids beautiful smiles and confidence, you did an amazing job :)

My daughter has been a patient with Dr. Tina Siu for a little over 2 years, and we have been very happy with the care and attention that Dr. Siu and her team have provided. Dr. Siu is extremely professional, has great bedside manners, and really takes the time to make sure the braces are being fitted and adjusted properly. We have total peace of mind and we are so glad that we chose Dr. Siu for our daughter.

My wife had braces when she was young, but didn't wear her retainers. So when her teeth started shifting again, we knew we had to find a good orthodontist. We asked around, read some reviews, got a couple of recommendations, got a couple of consultations, and were impressed by Dr Siu. Her staff was also very professional and friendly.

This is what my wife has to say: Shortly after I got my braces on, I got pregnant. Dr Siu and her staff were very understanding and accommodating. They were very patient with me because I couldn't wear the rubber bands all the time due to the need to eat all day! This prolonged the process but Dr Siu was very patient with the whole process and worked around it. I was a bit worried because usually people get braces when they are young, but my results are great! We went over the estimated time because of my pregnancy but Dr Siu did not remove the braces until she was satisfied with the results. A heartfelt thanks to Dr Siu, Kathy, Angie and Erica! I'm very happy with my smile!
