"Dr. Woo is phenomenal. I highly recommend and always will. I had to have a lot done with my teeth, from braces to double jaw surgery

it was quite timely. Dr. Woo always puts his patients first and makes the best decisions for them.

I’ve never felt like I wasn’t getting the treatment I deserved! He is an incredibly knowledgeable guy who has done so much for my smile.

I used to be so insecure about my teeth and underbite until I went to Dr. Woo and got them fixed! Now with my braces off and jaw surgery

done all I can do is smile! I encourage anyone who feels that they need their teeth fixed goes through Dr. Woo and his incredible staff.

What an amazing experience."

My wife and I are so pleased that Dr. Woo is taking care of three of our granddaughters. It is a pleasure to see how excited they are

to go to their appointments and to watch what is happening to their smiles. His interpersonal and professional skills are truly outstanding,

as witnessed by the way our granddaughters look forward to seeing him in his beautiful office and the almost miraculous improvements

in the alignment of their teeth. Before long our younger grandson will be visiting too. We feel very fortunate

to have our grandchildren under Dr. Woo’s gentle and expert care.

"Dr. Woo is wonderful. He inspires confidence and explains the procedures and the treatment very clearly. I was interested in what

he did to straighten my teeth as a craft, and Dr. Woo patiently answered all my curious questions about the process.

When I was a bit disconcerted by the rapid movement of my teeth at one point, I received a same day appointment,

an explanation, an adjustment, and answers to all my concerns. And the results of the work are great! My teeth are cleanly straight again.

Even my other two dentists have exclaimed with admiration at what a good job Dr. Woo has done with my teeth.

I am a completely happy customer, and I very highly recommend Dr. Woo and his staff to anyone and everyone."

“So happy that I decided to get braces! You’re never too old to get braces! Your smile is everything!

Would choose Dr. Woo all over again! Thank you sooo much!"

The office itself is cheerful, full of light and space, and whimsically decorated with Dr. Woo’s love of music.

The staff are all friendly, smiling, helpful, and kind. When one of my brackets broke free on a Saturday, I called the emergency number and

I heard back in less than half an hour, had an appointment that same morning, and was fixed up cheerfully by noon. Great service.

Great office! I sought many opinions regarding orthodontic treatment and many were trying to get me to start treatment right away

One office focused on fast and cheap, but I wanted it done correctly. Dr. Woo showed me all the options and there was no pressure.

He focused on what is best long term stable result. All the staff were great too, which made all the appointments enjoyable.
