I have just had my braces removed and the entire process was painless and efficient. Dr. Sim is very experienced with removing and inserting the braces so I was never afraid of getting hurt in the process. The staff is kind and helpful and I have had zero problems with scheduling. Would highly recommend coming here if you need any orthodontic services.

Decided in my late 30's to get ortho treatment, Dr Sim told me that he would fix my bite and give me a great smile, he delivered in both and I would recommend him to everyone.
