Dr. Robert Chen is the best orthodontist in the Silicon Valley Area. He can both speak chinese and english. I had braces for about a year and a half and now it is amazingly straight. I will recommend anyone to go to Dr. Robert Chen. He cares for every patient that he has. The office is a quite and comfortable place to release all the stress that you might endure. The front desk is very organized and very nice to everyone. Dr. Robert Chen takes anyone from a child to adults. He does invisalign and many other orthodontic procedures. I really recommend anyone who lives in the Silicon Valley to visit him if you have any othodontic problems.
